TSAA JOAD FAQ: |
|
This FAQ was created using information from some of Texas' best JOAD coaches
- alphabetically, Tom Barker, Jim
Krueger, and Alex & Racae Meyer. All of
their suggestions and data were merged into this html document by A.Ron
Carmichael who tossed in a few comments from his experience and many mistakes
he has made over the years or so of parenting and coaching an archer. copyright TSAA, 2001-2006 - all rights reserved, however this may
be reprinted and disseminated provided that it is done "for
free" and credit is given to those involved in formulating the guide.
That's small enough payment when taken with the knowledge of those that are
helped. Thanks also to the late Don
Branson, Jane Johnson (Past NAA
President), and Murray Elliott
(of Balbardie Archery/MURRAY's GUIDE fame) for
help in reviewing the material and helping me to maintain a positive
attitude. |

Safety First
The NAA JOAD program has a tried and proven method of teaching children, young
gentlemen and ladies, the sport of archery in a way that is SAFE for all.
It is the responsibility of not just the JOAD coach, but of you, your young
archer, and of every adult present at the archery range, to insure that the
safety rules are followed. Keep that in mind when you are watching your
child and others shooting, and do help the JOAD coach anytime it is
appropriate. And insure that your archer understands the importance of
this anytime s/he is shooting or is around someone
else that is shooting.
What's a JOAD and what's a FITA? (no, it's not a drink and a foreign
sandwich)
"FITA" is both the name (acronym/initials) of the leading
organization on archery standards for the world (Federation Internationale Tir
l'Arc) as well as the type of archery
round shot in the NAA
(National Archery Association) tournaments. Click on this link to go to the FITA
website.
JOAD is separate from FITA, it is a USA-only category of youth archers, the JUNIOR OLYMPIC ARCHERY DEVELOPMENT (JOAD) program. JOAD was created and designed by the US National Archery Association (NAA) to promote the development of Olympic archers. FITA has both adult and youth divisions, while JOAD is for youth archers only. JOAD allows archers to shoot fewer arrows per tournament at a larger target. JOAD Instructors and Coaches must go through training and testing to be certified by the NAA.
In order for our archers to compare and compete with other nationalities, the NAA adheres to the FITA standard for adult archers and has recently (2001) altered the JOAD program divisions to resemble the FITA divisions. Youth archers are free to shoot in both FITA and JOAD tournaments.
RIGHT HAND/LEFT HAND
In the NAA JOAD system, the eye dominance of the archer is
what decides which side of the bow the arrow should be placed on,
and which hand the archer uses to draw the bowstring.
A "Right Hand" bow means that the archer DRAWS the string with the right hand (and is usually right-eye dominant). Some archers are left handed but are right-hand archers, and vice versa. It all depends on eye dominance. The JOAD coach will verify eye dominance as one of the first things done with each new archer. You can check your own eye-dominance this way: Hold both hands out in front of you at arms' length and make a small circle with your hands, that you can see through. Now focus on a point (say a picture on the wall, or the TV) with this "peepsite" and keep looking at that point as you move your hands towards you. As the hands approach your face, you will discover that the peepsite has gone to one side/eye or the other. The eye you kept using as the hands drew near your face is your dominant eye. This technique is useful for coaches trying to assess a new archer, since the coach can see which eye the hands went to. Another method: Instead of moving the hands towards the face, after you sight in on something through the peephole, simply close first one eye, and the open it and close the other. The object you have sighted in on will not move when you close your dominant eye. If the object disappears (your hands appear to jump to one side) then you have just closed your DOMINANT eye. Try it and see! (but don't do it around your kids - they probably think you are weird enough as it is.)
The importance of eye dominance is to develop the archer's ultimate potential. An archer can shoot with using the non-dominant eye to sight in with but it may require a patch, a squinted eye, or some other trick to help aiming. All these tricks ultimately handicap the archer from achieving the potential that would be possible if they used their dominant eye. Just as having the wrong eyeglass prescription can interfere with the best performance in school, using the weaker eye to sight with may prevent the archer from having the best success s/he is possible of attaining.
By the way, cross dominance is more prevalent in the ladies than in the men. A Field and Stream article a few years back talked about shotgun shooting and this situation. Also, very young archers (6-8 years) may not have settled on a dominant eye yet and may switch from week to week.
Sometime a coach may have the archer use a non-dominant eye when the parents have shelled out the money for equipment already just because they assumed that since she was right-handed that she would also shoot right-handed. It is indeed possible for an archer who has spent months using the weak eye to SWITCH to the dominant eye/stance, but it always causes a temporary decrease in score which cause psychological problems for the youth, ranging from mild irritation to completely giving up on the sport. Once the mind accepts the changeover, the archer will usually go on to achieve new personal bests. It is not unusual, by the way, for the archer's score to DECREASE when a new piece of equipment is added or when a technique is radically changed.
Also, the Koreans have decided to use the ARM dominance of the archer to determine which bow riser (left or right) to use, and the Italians are also trying it out. Just another example that in archery there are very few total absolutes.

PERSONAL BEST? (Do you really have to get personal?)
Each archer progresses and improves at her or his own rate. One of the
primary goals of the JOAD coach (after safety) is to provide positive
reinforcement - never negative! On any given day an archer will shoot
either better or worse than the last time - this is natural and the coach
teaches that this is inevitable. So it's more important for the archer to
compete against his or her "best" score
ever shot rather than just against other archers. This is the "personal best"
(PB), and each archer keeps
track of the personal best and shoots to "best" it. It has been
said that the most worthy opponent is one's self and this holds true in archery
as well.
What's the difference between bows: Compound, Recurve, Olympic, Barebow
(so many choices!)
The barebow is the closest to the original bow when you think of "bows
and arrows". It is archery in it's simplest form - a bow, some
arrows, no sight, no pulleys, no add-on equipment aside from an arrow
rest. The appeal of barebow is that it takes a lot of effort to get
reasonably good with one, yet archers can be remarkably accurate with one.
The simplicity of the bow keeps costs down as well.
Generally, archers must invest much more time to be "good" with a barebow, the least time/effort to be "good" with a compound bow, and somewhere in the middle of those with the recurve bow. Many times archers will start with a compound and end up shooting barebow for the "pure" nature of the barebow, and many archers will actually have two or even all three bow types just because it is fun!
Barebow archers (and all other archers) are allowed to use:
Everything permitted or found on the barebow is also available for the Recurve/Olympic and Compound bows.
Recurve or "Olympic" bows (the names are interchangeable) start with the same shape of bow as the barebow. "Olympic" because this is the only style of bow allowed at the Olympics. Barebows do not provide a level of accuracy sufficient to be competitive at the 70 meter Olympic distance. "Recurve" because the bow actually has a middle curve and then a second curve, a recurve, at the tips of the bow, are allowed to have many more enhancements to the basic barebow, such as:
Archer's Paradox? you shoot, it goes, what's the paradox?
This term is subject to some interpretation and argument. Essentially,
when an archer uses her fingers to pull the string back, no matter how fast and
cleanly she tries to release, the bowstring will always slide sideways off of
the fingertips, putting sideways thrust on the tail end of the arrow. No
matter what the arrow shaft is constructed of and no matter how much spine (stiffness) the
arrow has, it will bend in the middle as the back end starts to accelerate and
the front of the arrow resists the change from "at rest" to
"in motion". As a result of this bending the arrow does some
uniform distorting which can be clearly seen when viewed in ultra-slow-motion
video. Check the high speed video link at the top of the photographs index page of the TSAA website. I feel tht the "paradox" comes from the fact that the arrow is not pointed
straight at the target during the aiming portion of the shot, but is actually pointing off to the side in anticipation of
this distortion. If you want to hit the target you would expect to point
the arrow directly at the bullseye, and since you don't, that is a paradox.
Compound archers typically use a mechanical release, which is a device that an archer holds in the string hand, that in turn holds the
bowstring and reduces drastically or even eliminates Archer's Paradox.
PLUNGER, CUSHION, BUTTON - gee whiz! just how many terms are there to know
for archery
As mentioned above the arrow is going through some distortion during
release, acceleration, and flight. Ever held a long thin stick in the
middle, and "wobbled" it back and forth, so that the ends flop up and
down or back and forth in unison? The ends of the stick will continue to
wobble even when you stop push-pulling on the middle. An arrow in flight
shot from a finger-release will have these same oscillations as it goes from the
bow to the
target. Under the worst circumstances, that wobbling might make the tip of
the arrow land well off of the bullseye. So the cushion plunger was
created to act as a bumper and tuning aid. Essentially it is a
spring-loaded plastic stick attached to the bow such that it holds the arrow at
just the right angle OFF to the side of the target to allow for the archer's
paradox. It also has an adjustable spring that will push back against the
arrow as the arrow starts to bend, in the first few instants of time after
release. This dampens those wobbles, those oscillations that might make
the shot less accurate.
TUNING? Is the bowstring supposed to make a particular musical note
when shot?
The recurve bow is like a musical instrument - the better it is in
tune, the better it will play. Tuning is the process of adjusting the
various parts - the string, limbs, rest, plunger, arrow, and archer so that they
all work together in balance and harmony. It takes a lot of experience and
understanding of the mechanics of archery before one can tune a bow effectively. The string
must be the right number of strands for the weight of the bow. The arrow
must have the right SPINE for the bow weight. The nocking point must be at
the right place on the string for the diameter of the arrow. The plunger
must be set in coordination with the arrow rest, the nocking point, the spine of
the arrow, and the technique of the archer's release. Moving one component
has effects on the other parts! Tuning has many
methods - check the TSAA website under Documents for several guides.
Compound bows are typically shot with a mechanical release so archer's paradox
is not a factor, and no cushion plunger is needed either. Tuning a
compound bow involves more absolute measurements of string length, pulley
timing, arrow rest adjustment, etc. and is generally more of a science and less
of an art (the way it is with a recurve). And no, there is no specific
note that the bow should make when shot, but many archers will add or subtract
twists in the bowstring (thereby making the string longer or shorter) so that
the bow will "sound" better to their ear, as part of the tune
process.
Why is a stable ANCHOR POINT important?
Success in archery depends on consistency. The archer will be taught
to bring the bowstring close to the side of the jaw just before releasing the
arrow. The ANCHOR POINT is the place on the face where the stringhand
comes to rest on the archers jaw. Hopefully it will be the same place for
each and every shot. Even very small variations in the anchor point between shots can mean the difference between a 10 and a 5
(or even a miss!) You may hear the phrase "bone on bone" -
where the knuckle of the index finger is FIRMLY against the underside of the
jawbone.
Compound bows
Compound bows are a product of modern knowledge and technology. Their
appearance readily shows that there are major design differences from the
recurve bow. One or two wheels are used to use leverage to make the bow
easier to shoot than the recurve, and to make the arrow go faster. They
are typically shorter than recurves, so they are useful in hunting blinds.
They are able to shoot the arrow faster, flatter, so knowing the distance to the target
becomes less crucial. Another benefit to the arrow delivery is that it
will shoot it faster so that in hunting, the game target will have less time to
react to the sound of the shot and move. With eccentrically-shaped
wheels on the bow that provide "letoff" the archer doesn't have to
hold as much weight while aiming to shoot the bow. The mechanical
release that compound bow rules permit reduce archer's paradox (see AP below).
Letof means that while the bow requires
The rules for compound bows permits the sight to actually have a scope (optical magnification) so the target is magnified. The sight can also have electronics, such as lights, to illuminate the crosshairs in sunset/sunrise lowlight hunting conditions. At longer distances, the bow must be held in a consistently vertical position for arrow accuracy. Barebows and recurves are not allowed to have "bubble levels" which compound sights routinely employ. All of these modern enhancements contribute to making the compound bow potentially much more accurate and easy to learn and shoot than the other two styles described above.
Only recurve bows are allowed in the Olympics, but currently there are many tournaments for compound archers that offer sizeable money awards. There is also a friendly (usually) rivalry between the three disciplines, but at the end of the tournament all are still friends and archers. The typical barebow archer will haughtily observe that everyone else's bows are loaded down with junk, recurve archers will likewise point out that compound archers need training wheels, and compound archers, well, they have their disparaging remarks to make as well, but it is the humor of compatriots and is usually good natured.
What length bow should I buy?
The preferred length of a recurve or barebow partially depends upon the draw length of the
archer. The following table is a good initial guide for recurve/Olympic bows but the JOAD Coach will be
able to provide a more accurate suggestion to start with.

Why is the length of the bow important? (one hand on the bow,
one on the string, what more do I need?)
A recurve bow has a curve near the tip of the bow, both top and
bottom, that is sometimes called the "deflex" or "recurve". Without going
into a physics discourse about it all, properly using this curved part of the
bow is very important in making the arrow "go". If the bow is too
long, the archer will not be able to stress the recurve section during a shot
and the arrows won't go as far (that's "cast").
Also, the arrows will be more difficult to choose and the bow more difficult to tune, since the arrow spine charts are based on the expectation of the archer choosing the right length bow. If the bow is too short, the deflex will be completely stressed, but then the lower, thicker, heavier part of the limbs will also be stressed (too much), and as they are stressed the resistance of the bow climbs, resulting in "stacking" which interferes with the archer making a good shot. Stacking is where the bow increases in draw weight as the length of the arrow/draw length increases. As an extreme example, I have a 32inch draw length which causes a pair of limbs rated at 34 pounds to stack up to 42# at click. So I have to draw more and more poundage as I get closer to the end of the arrow, which makes it much harder to be smooth and consistent. Stacking also varies depending on the way the limbs are made - modern limbs have, generally, much less stacking than the older, less exotic wooden limbs.
A last problem with having the bow length too small is that the string fingers will be "scrunched" together more because of the angle of the limbs causing the angle of the string at the arrow nock to be more acute. This is known as arrow pinch, and makes an archer VERY inconsistent. The fingers should NOT be touching the arrow's nock, but with a too-short bow (or one with too much poundage) this becomes hard to avoid since the sharp angle of the string literally squeezes the fingers into the arrow nock.
CHOOSING A COMPOUND BOW
Compound bows require careful measurement since they do not have the
flexible range of draw that a recurve typically has. This is best done at
a good archery shop, by an experienced archer/salesperson. This usually
excludes the department store sporting goods bargain outlet. You may find
cheaper bows there, but will quickly lose the price advantage when you end up
with the wrong bow. Caveat Emptor.
An important point on the compound bow is that in most cases they are for a narrow range of draw length, so for a youngster, every 6-12 months as they grow they may need a new bow. If you are in an area with lots of youth archers there is a pretty good resale market. But many times you can be stuck with a bow that a youngster has grown out of. (You can always check the TSAA's FOR RESALE page to look for bargains in second-hand equipment)
The simple recurves that JOAD clubs typically use will work for many kids of different draw lengths and for many years.
Is a Dry Fire as good as a dry heat?
NEVER ever should a bow be fired without an arrow (known as dry firing) -
today's bows can be damaged, limbs shattered dangerously, by pulling back and letting go of the string if an
arrow is not nocked. In addition, the nocking point may actually fly off
of the string, causing injury. And that's not cool.
Should a youth archer shoot fingers or a release with a compound bow? (well,
they don't actually shoot at fingers, that's actually "shoot with a finger release or a mechanical release"
but any archer would understand the question)
This is one of the most frequently asked questions for the new compound archer and one of the most difficult to answer. In the long run an archer will be more
accurate and the bow more forgiving with the archer using a release aid. It is very difficult to be competitive at state and national competitions using
fingers with a compound bow.
Besides, the youngster sees Mom, Dad and all the other compound shooters using the release aid and they believe they should use one also. Having said that, it is
better for a young archer to start out shooting fingers. a good analogy is when a young person begins to move from a crawl to a walk. They don’t go directly from
the crawl to a sprint. It is better to learn to walk before learning to run. In archery it is better to learn the proper form
and technique by shooting with the fingers before advancing to the release aid. If the toddler went directly from the crawl to the sprint they would fall many times. The "falling" in archery is called trigger punching. What happens when the
inexperienced youth archer starts out with the release aid is that as soon as they acquire the target with the sight through their peep site, they will punch the
trigger, which spoils the aim and the shot.
The punched trigger and the drive by shooting leaves an arrow pattern like it was shot from a shotgun. Once punching begins, it becomes subconscious and it is
very difficult to rectify.
If it is absolutely imperative that a youngster shoots a release aid (Mom or Dad said so), then ensure that it is one especially designed for youth archers. Also, the
release hand should be relaxed, the archer should pull with their back, and a large percentage of the practice is done up close to learn the proper way to activate
the trigger. Shooting the release aid will ultimately help them become a more accurate archer, but they must walk before they can run.
How much weight should the bow have?
By "weight" we mean the resistance to drawing, not the number on
the bathroom scale when you put the bow on it. (Although for JOADs, lighter would
be better for that kind of "weight"). The weight of
the bow is rated in pounds of bowstring resistance. It is usually measured by hooking the
bowstring onto a hanging scale, and pulling down on the bow until the distance
from arrow rest to string is 28 inches. (the standard distance used by bow
manufacturers for this rating system). Most JOADs will NOT be
drawing their bow back 28 inches, depending on their physical size.
Most numbers in archery bowkits are not absolutes, but rather approximations. Your 7 year old archer may be able to press 200 pounds, in which case a larger draw weight would be in order. A rule of thumb that Tom Barker likes to use for selecting the right draw weight TO TRY OUT for a JOAD kid is to take the age times 2, e.g. an 8 year old times 2 is 16 so a 15 lb bow is about right to start with. This works for recurves only. On older kids obviously the curve flattens out, and common sense must rule. (He would not, for example, recommend a 40 lb bow for a beginning 20 year old.) JOAD Ladies may be a little less than 2 and some JOAD Gentlemen may have a multiplier factor a little more than 2.
As for the weight of the bow itself - this is important for beginner archers as there is a wide range in the weight of the riser. 23" risers are lighter than the adult size (25").
OVERBOWING! What's a good bow? How strong should it be?
For JOAD archers, less is better. Perhaps the single biggest mistake
for a parent is in providing a bow that is too heavy for the young, growing
archer. Also known as "overbowing" , too heavy in this case
means having too large of a draw weight. In many cases it's very
obvious when a youth has to wildly arch his or her back and struggle to get the
bow drawn, and it is also very dangerous to other archers and bystanders if the
archer cannot control the bow's direction during this struggle to draw the bow.
It may not be quite as obvious in some cases - if your archer cannot draw and
hold the bow for 10 to 20 seconds or so without severe trembling then the bow is
likely to be too heavy. It is important that the
bow have enough weight to get the arrow to the target but any more than that is
not necessarily better and in the case of growing kids with open growth plates may
actually cause harm to their bones. Youth archers will typically start with 15 to 25 pounds
using a recurve bow.
It is important that the under-16 archer NOT start lifting weights in an effort to make himself stronger unless it is done under the supervision of a qualified expert such as a sports physiotherapist. It can cause permanent damage and stunted growth, and is not necessary. Shooting a properly weighted bow will be great exercise in and of itself. My own 15 y.o. daughter's got a set of biceps now that puts many of her non-archer male classmates to shame, simply due to a high number of reps with a low weight bow.
On this subject, it's important that the archer always take time to stretch
and warm up and stretch again before actually starting to shoot each time.
MANY injuries are caused by inadequate preparation just before the sport.
Bungee cords, elastic bands, small weights, and various motions can prepare the
muscles and body for shooting in just a few minutes and prevent long-term
problems. EVERY top archer stretches and warms up, and young archers
should imitate them!
Also, see "Pinching" for another problem associated
with overbowing.
IF IT HURTS, don't do it!
There is nothing intelligent about "playing through the pain" when
it comes to the sport of archery. If injury is suspected, STOP
IMMEDIATELY! Injuries must be allowed to fully
heal and the cause properly diagnosed. The archer must be able to be completely calm and under control when
releasing an arrow, and if s/he knows that it's going to cause a stab of pain to
release the shot, the shot will not be good and frustration will mount.
Also, if it hurts to shoot a bow then the archer is likely doing something wrong
that a coach can help correct.
Grown men will typically use a recurve bow weight of between 40 and 50 pounds, and grown women from 30 to 45 pounds. For most of these male archers and perhaps some women, they are using a bow that is heavier than they really need. Denise Parker, a well-known (now adult) recurve female archer, won her first national adult title using a 28 pound bow shooting at up to 70 meters distance! The arrows may have flown like a mortar round, but technique trumped power without a doubt.
Women, shooting less weight, are able to score as good as (yes, and better) than men, even when shooting in less than ideal conditions such as the occasional high winds seen at Sydney. Consider this recent example, using the top ten male and female archers in the 2000 Olympics in Sydney, Australia. Note that women (in PINK) and Men (in BLUE) are very evenly distributed based on their actual scores but that women are the more consistent performers overall. This makes a very good point about how much bow weight is actually needed by anyone. It also reinforces the earlier statement about archery being a truly "equal" sport for both women and men.
In addition, as of this writing (2/2006), the world's highest score to have ever been shot in a FITA round is 1405, shot by a female Korean archer. Yes, a woman holds the highest score record ever shot with a recurve bow: 1405 out of a possible (perfect) 1440! In fact, she, Sung-Hyun Park, has had a great year or two:

WHY IS THAT KID'S BOW SO FANCY?
The hardware described in the bow description above: Front stabilizers, side stabilizers, clickers, wrist slings, finger slings, doinkers, kisser buttons, etc. are all important components that help a better archer shoot a little
better once their form has developed to where they can take advantage of these tools.
In the beginning, a JOAD archer needs only a bow with arrow rest, arrows, finger
tab, arm guard, and perhaps a chest protector (esp. for ladies). Adding a
sight is the first logical enhancement, and many others can follow.
Another important consideration is the psychological effect of new tools. The young archer sees the other archers with a long stabilizer and THINKS it will help
them shoot better. When they try one and scores improve, are they shooting better
because of the new piece of equipment or is it psychological?
This uniquely human phenomenon is called the Pygmalion Effect. It is a persistently held belief in another person (or yourself) such that the belief becomes a reality.
The person believed in, being believed, becomes the person whom they are perceived to be.
It's the self-fulfilling prophecy, for real.
Because the effect may be psychological, there sometimes is an advantage of not adding all the
auxiliary equipment at once. Maximum benefit can be obtained from spreading these additions out over time.
Parents have been known to actually use these add-on pieces of equipment as
"carrots" to lead the archer into doing chores, homework, or the like.
One important consideration is that the bow is already fairly heavy. Adding these extra hardwares can be very counter-productive for the young archer. It's important that once you find the good basic bow for your archer, any and all changes are made in small, minimal steps so that the archer doesn't suffer a depression of ability because of the distortion caused by excessive changes.
What is the best material for a bow riser(handle)?
There are currently four materials listed in order of cost that the modern bow handle is made of; wood, aluminum/magnesium, machined aluminum, and
composites (carbon or ceramic). Wood is what most youth archers start with because it is the least expensive and some of the laminated wood bows will last a
long time. Wood is very good choice for the beginner and allows for the development of the proper form. It is also good as an initial bow until the parent decides
if the youth archer is going to stay with archery or not. But wood is usually not seen at the more competitive levels in target archery. The grip on a wood bow is
substantially thicker than the other materials dues to the strength of the materials. The fragile wood does not have the strength to stand up to the rigors of the job if
it were whittled down to a narrow width. Wood also changes its physical properties with temperature and humidity.
Cast risers of aluminum/magnesium is the next step up. This adds much more strength than wood and has been well adopted into archery competition. However
at higher poundages and the demands put on modern equipment of reduced weight, higher strength, etc. manufacturing flaws inherent in the casting process can
lead to catastrophic failure.
The next riser generation is machined aluminum which is made from a solid piece of aluminum. This makes the handle much stronger than the cast or wood risers
and can be made much smaller in the grip area. Additional features such as adjustable limb pockets, stabilizer bushings, center shot design, dovetailed rest plates,
etc. can be economically added to the handle. A recent upgrade of this design is the isogrid or "tech" seen in the Hoyt bows to take out weight and improve
shootability.
There are all carbon and ceramic risers out there but they tend to be quite expensive and have not demonstrated a competitive advantage over the machined
aluminum handle. For a much more detailed view of riser material and a glimpse into the riser of the future, George Tekmitchov from Hoyt wrote
an in-depth piece in the May/June 2000 "Archery Focus" magazine.
Should I use wood, aluminum or carbon arrows?
Before making an educated choice on arrow shafts, you
need to know what the choices are.
For the beginning JOAD archer, especially at scout camp or the local YMCA, wood (or even fiberglass) arrows are used because of their low cost. Wood and fiberglass are quite sufficient for beginners and work well. It's only after the archer has begun to group well that s/he will need "better" arrows.
Better arrows are made from aluminum or carbon/graphite, or both. Usually archers use aluminum arrows indoors, because crosswind is not a factor and scores often are closer to perfection (making each point count more). Outdoors, carbon arrows are smaller in diameter and therefore less affected by winds and air resistance, able to fly further. On average carbon arrows are more expensive. If your young archer is not sooting really well, it is hard to justify purchasing carbon arrows that are "above" the archer's ability to score good shots.
What's so good about "GROUPING"? (My kid's an individual!)
When an end of arrows is shot, they will typically make a pattern on the
target. The pattern for a beginner is naturally going to be pretty
"all-over". The "grouping" of the arrows is very
low. An expert archer will have a group of arrows that is much
closer. So there is actually two ways of judging an archer's performance -
the score of the arrows shotshot, naturally, but also the tightness of the
"group". It's very desirable for an archer to be consistent -
and the grouping will reflect the consistency of the archer. A very good
group of 3 arrows shot indoors at 18 meters would be for them to be within 1 or 2
inches of each other - many times they may actually be touching each
other!
Enough about grouping, back to arrow materials:
Aluminum arrows are produced using different grades of alloys that feature various degrees of strength, straightness, and, of course, cost. To the naked eye all aluminum arrows appear to be perfectly straight, so how does one know which arrow to buy? Most JOAD Clubs will have the inexpensive (but quite good) Easton Jazz or Platinum aluminum shafts. These are fine for Recurve bows.
Higher powered Compound bows normally need to use a more durable shaft. For compounds, the least expensive arrow shaft produced by Easton (the leading manufacturer of aluminum arrows in the world) is the Eagle Hunter. Produced from the 6061 alloy, Eagle Hunter shafts offer a strength rating of 58,000 psi and a straightness factor of +/- .010 of an inch.
The next step up the ladder, Game Getter II arrows, are made from 7075 alloy (96,000 psi) and offer a straightness factor of +/- .003 of an inch. The popular XX75 shafts are also made from 7075 alloy and are straightened to +/- .002 of an inch for even better arrow flight and improved accuracy.
The new XX78 Super Slam is Easton's strongest, lightest, and straightest aluminum hunting shaft. Made from bend-resistant 7178 alloy (100,000 psi) these shafts feature an incredible straightness factor of +/- .0015 of an inch. These arrows also feature the Super Nock and Super Uni Bushing that allow the nock to be moved, making it easy to index arrows (adjust the nocks) to any arrow rest in seconds.
Easton also makes the X7 aluminum shaft which has a 105,000 psi tensile strength and a +/- 0.0001 straightness. These shafts are extremely hard and are prone to cracking.
Still reading? Haven't run screaming from the room? Good. So what does this plethora of techno-babble mumbo jumbo about alloys and straightness factors mean? The straighter an arrow is made, the more accurately it can be shot from a bow. Archers should purchase the straightest arrows they can afford. Most archers will find the aluminum XX75 or XX78 Super Slam series arrows offer the best performance and value for the money.
XX75 shafts retail for around $40 a dozen (plus a few bucks more for feather fletching), and the XX78 Super Slam arrows average $50-$60 per dozen. (Arrows are often sold by archery shops in the "dozen").
If you're afraid to try carbon/graphite arrows, don't be. A lot of false information about graphite arrow durability has been circulated leaving archers confused. Graphite arrows are among the most durable shafts available, and in fact they are far more durable than comparable aluminum shafts.
Carbon graphite shafts have some specific advantages over aluminum arrows. The durability factor already outlined is an important consideration for the target archer who shoots frequently.
The smaller diameter of graphite arrows also allows them to fly somewhat faster and with a flatter trajectory than comparable aluminum shafts. At 10, 15, or 20 meters the speed and trajectory advantages of graphite arrows aren't noticeable as compared to aluminum shafts. However, at the outdoor ranges from 25 meters to 90 meters graphite shafts provide the target shooter with a pronounced flatter arrow trajectory and superior long-range accuracy. Since the graphite arrow has less of a profile they are less influenced by crosswinds.
Top-of-the-line graphite/aluminum arrows like the Easton ACE or X10 offer a straightness factor of +/- .0002 of an inch, making them comparable in straightness to the best aluminum shafts available. They have a weight tolerance of +/- 1.5 grains. Virtually every archer at the last olympics used X-10 arrows. On the bottom end of carbon-type arrows there are ACC shafts.
Graphite arrows are more expensive than aluminum. Like aluminum arrows, carbon shafts are available in various straightness factors and price ranges. Graphite arrows require special nocks, point adapters, and arrow rests.
There are two major disadvantages to the carbon shafts other than the obvious cost factor. Most pure carbon shafts are not as straight as the comparable aluminum. Also, the all carbon shaft cannot be straightened if it is damaged/bent from striking a hard object.
The combination carbon/aluminum shaft mitigates this somewhat, but at an increase cost.
Most target archers use the larger diameter aluminum shafts indoors, but go to the faster, flatter trajectory carbon arrows outdoors.

SCORING by the rings
By shooting a fatter aluminum shaft indoors, the archer may make a slightly
higher score. This is because when an arrow comes to rest ON a line
(breaks or cuts the line of a higher score color) of a target then the arrow is
counted on the higher ring. This shot is called a "line
cutter". The score is determined where the arrow comes to rest,
NOT where the hole is. If the hole breaks the line, but the arrow shaft is
actually NOT on or over the line, the lower score prevails. Archers are limited now to arrows no wider in diameter
than 9.3 mm.
On the other hand if an archer's arrow is fat then as the next arrow arrives it
may be forced out to a lower score because it glances off of the fatter
arrows. The best archers shoot smaller diameter arrows as technique
will usually triumph guppies (huge arrows).
SPINE? (Is it bad when my arrows have a weak spine? are they cowards?)
Each arrow's backbone has a certain resistance to bending or flexing as it is
shot. This is determined by the thickness of the wall and the diameter of
the shaft, as well as the material used in making the shaft relative to the
weight of the bow (see tuning). The
more pounds of resistance in drawing the bow, the stiffer the arrow or the more
spine it should have. The arrow's behavior becomes less manageable
when the spine doesn't match the bow. There are charts provided by the
manufacturer (Easton) to help the archer pick the appropriate spine/shaft to
shoot. It takes into account the variables of bow strength/weight, and
arrow length (among others) to try to predict which shaft will give the most
consistent and reliable performance.
Arrow Size
From the
Easton Document page:
Easton uses various arrow shaft outside diameters and wall thicknesses to obtain
the necessary number of shaft spines needed to shoot well from nearly all bow
weight and arrow length combinations. The outside diameter is the main factor in
determining shaft stiffness, AKA "SPINE". This diameter is coded in the first
two digits of the shaft size number—for example, in 2312, the 23 = 23/64". This
is the shaft diameter rounded to the nearest sixty-fourth of an inch. The wall
thickness code is the second two digits of the shaft size number. These digits
indicate the shaft wall thickness to the closest one thousandth of an inch—for
example, in 2312, the 12 = 0.012". The wall thickness is the main factor in
determining the shaft weight. For two shafts of the same stiffness, a larger
diameter, thin-walled shaft will be much lighter than a smaller diameter,
thicker walled shaft. In NAA competition, the largest arrow you can
legally shoot is 2317.
Which are better, plastic vanes or feather fletching? (or why do arrows
have feathers?)
Arrows often fly through the air at more than 100 miles an hour.
Aerodynamics have a lot of influence on the accuracy of a archer's shot.
If the worlds' best archer shoots a shaft with no fletchings, the score will
still be very high. Their good technique will offset the bad aerodynamics
of the bare shaft. But for the vast majority of archers, the fletchings
are necessary to average out the flaws of the shot. Fletchings cause drag,
which is why they are applied to the back end of the shaft instead of the point,
this keeps the front end of the arrow pointed downrange to the target during
flight. The arrow itself may have small flaws or a weak spine, or
the archer may not release the shot cleanly, and the arrow would therefore tend
to curve or veer off. So the fletchings are aligned to make the shaft
ROTATE as it flies through the air. Any flaw on the shaft will
therefore, due to rotation, spread it's bad influence evenly over the 360
degrees of rotation, so that the AVERAGE effect of the flaw is still to the
center of the flight.
SO WHICH ARROW IS BETTER?
The answer to that question depends largely on shooting style. There are no
wrong choices, only personal preferences. Archers who shoot aluminum arrows using finger tabs or
gloves are usually best serviced with feather fletchings. The natural texture
and softness of feathers allows them to grab the air and quickly stabilize an
arrow as it speeds towards it target. Feather fletching compensates for minor
flaws in the arrow release, allowing for consistent shooting accuracy despite
human error.
Feather fletching is sold in left- or right-wing (or left-hand/right-hand) versions. A subtle right- or left-hand twist is used when gluing turkey feather fletching onto the arrow shaft. This slight twist in the feathers helps stabilize the arrow during flight (causes rotation) and gives better accuracy. The feathers that are derived from turkeys (the vast majority of feather fletchings come from turkeys) are segregated by whether they are from the left or right wing of the turkey, as this determines whether the fletchings are right-hand or left-hand in nature.
Natural feather fletching isn't without its problems. A lack of durability is a common complaint of some archers. Feather fletching is easily matted (making them ineffectual) in wet weather and can be quickly damaged if the feathers come in contact with the target or other arrows while practicing.
Plastic vanes are more durable that feather fletching and they provide excellent arrow flight when used properly. Those archers who use compound bows and mechanical release aids will find plastic vanes deliver consistent accuracy in all conditions.
Plastic vanes may be attached to the arrow shaft in a straight, left-wing, or right-wing pattern. The most common configuration is a slight right-wing twist. A slight twist in the vane helps the arrow stabilize arrows quickly resulting in better accuracy.
Plastic vanes are also available in different styles and sizes. Style normally relates to the vane height and size to overall length.
Three fletch (two hen feathers and one cock feather) arrows are the most common with target archery buffs.
A special kind of plastic fletching is the mylar spin wing. This is used on the smaller-diameter carbon aluminum arrows and provides a lower profile, less drag and thus better long range accuracy. It is attached in straight-line alignment to the shaft.

TARGET PANIC: (The targets do not shoot back; what is the deal?)
This is something I would rather not be able to write about from first-hand knowledge. Target Panic afflicts most good archers at some point in their career. It will help you to understand it BEFORE it happens to your archer, so that IF and WHEN you might see it in an archer you know or coach, you will understand just a *little* bit better.
Target Panic has a number of names, and it afflicts athletes in a number of sports. Any sport where the athlete has at least a moment to THINK about an action is a candidate sport for the equivalent of Target Panic. Essentially, the conscious mind steps in and interferes with what should be an almost-unconscious action of the body. A baseball catcher stands to return the ball to the pitcher, and it sails into the infield over the pitcher's head. A golfer tries to address the ball for a simple putt, or a drive, and completely flubs the shot. An NBA star goes to make a free-throw shot, something he does thouands of times in practice, and it's a brick that thds on the rim before falling out of the hoop.
In golf it is called the yips. In archery, target panic. It only affects *good* archers. New, basic, naive archers shoot without consciousness naturally but in the normal progression of excellence an athlete inevitably begins to ask "why" and "how", and their mind gets in the way of a perfectly simple process. You cannot predict when nor why. The archer may be asked to adopt a slight legitimate change in form by a completely legitimate and expert coach, only to affect the archer in a completely unexpected way. Once it starts, it may cause only a mild perturbrance in the archer's path, or it may destroy an entire career, driving the athlete from the sport.
Many "coaches" will make their entire career an effort to teach others how to NOT experience TP. The problem as I see it is that every person finds their own particular way to establish panic in their mind about making a simple mechanical process with the upper body. The disconnect has profound effects you will not even begin to appreciate until YOUR archer goes into that dark room. First, accept that you may not be able to help your archer find a way out of that room. That space. That dark forboding hell. Melodramatic? no. If you can put yourself into a space where you want to simply touch your nose with your eyes closed and cannot, then you may begin to understand how the simple art of shooting a bow is so difficult for someone with TP. In one case, the archer has superb form during practice. But when the tournament starts the archer performs 99.5% of an entire shot cycle but fail with the last 0.1mm of draw - the part that takes the tip of the arrow past click. Something in the archer's conscious mind simply intereferes with that unconscious process that the superb archer relies on. Aiming is after all, best performed with total innocence and unconsciousness. Once an archer starts down the road of "thinking" about how the shot is accomplished, many will be unable to continue improving.
When the archer has TP, he or she will become terribly frustrated. A coach must be completely, completely non-judgmental about this. You, the parent or the coach, cannot FORCE the archer to NOT HAVE TP. It is just not that simple. If it happens to your archer you need to be supportive, open to explanation, completely interested in *any* revealing emotions and thoughts the archer is willing to share with you. You can make suggestions, you can take "an attitude", but in 99+ % of the cases you will simplly help to destroy the athlete;'s future as an archer.
If you can regress the archer to before the point of the infection (and this is a viral infection of the mental sort) and help him or her to understand what is going on, the archer MAY be able to grow out of the hole. You can HELP the archer, but you cannot FORCE the archer. As much as you might wish to just MAKE the archer shoot as he or she did before, it likely will not happen. You CAN MAKE IT WORSE if you are not careful. My advice is to find a new coach, an HPP coach, that can introduce huge evolutionary changes in the archer's form that MAY help to actually distract the archer to the point of laying down a new mental track for shooting.
It can be a real bear. I am sorry there is no one sure cure. Do not believe anyone who says there is, he is only selling a snake-oil product that has little chance of success. (but not a 100% useless chance).
