Modern Archery Equipment and Terms

Bow
The bows of today differ mainly from those of yesterday in materials. Wood is still the most common material, but molded fiberglass, tubular steel, and plastics replace the more "natural" elements of design. Even the old gut bowstring is being replaced with linen, Fortisan, or Dacron cords.
LongbowThe longbow of today is quite similar to those used in history. It is made of a single piece wooden stave, string, and handgrip. Sometimes a sight is used.

RecurveOriginally one piece bows, they are now usually made of three pieces, the risen and two limbs, which are of layered, laminated carbon. It is currently the only bow used at the Olympics.
Recurve Bow
CompoundThis bow was originally used only for hunting, but has gained popularity for recreation. It has two pulleys positioned on the tips of the limbs, which allows the archer to hold the bow with less power than the amount it fires the arrow. It is usually smaller than the recurve with movable limbs that can be set to different strengths.

Handle/GripHandles are used on recurve and compound bows. They are usually made of plastic or wood. Different types of handles are used for producing different kinds of shots by holding the bow in different positions. Handles and grips are generally chosen to fit the individual and bow.

Bow handle

Riser/HandleThe riser is the middle part of the bow that holds together most of the equipment attached to the bow: limbs, sight, button, etc. Different risers effect how the bow is held, though the effects with a riser are more noticeable than the handle (riser is sometimes called a handle). Some risers have aerodynamic qualities such as holes which let wind pass through it rather than disturbing an archer’s aim.

Riser/Handle

LimbsA bow is not a bow without its limbs, which are the longest pieces of the bow. They bend with the draw and they produce the power of the bow. The limbs attach to the riser. Special limbs require special risers and vice versa. Many limbs are layered of different types of material to make it more smooth, that is, with a smooth bend ability and make it resistant to deformities, thus allowing greater consistency and greater accuracy. Recently limbs can be made of carbon, which is a lighter and more efficient material.

Bow limbs

StringStrings are usually made by twining several strings of Kevlar or Dacron to make a single cord. Dacron is cheap, but prone to creep, meaning that it may stretch and make for inconsistent shots.

Bow string

RestThis is where the arrow sits right before being shot. The longbow has no rest beside the hand, which can be kind of tricky because of the shape of the hand. Other bows use plastic or metal rests, while some more complex bows may be fitted with a magnetic rest. Compound bows are sometimes fitted with vibration sensitive rests. These rests collapse as soon as the arrow is released to prevent it from hitting the rest which could knock the arrow off course.

Bow rest

Button i.e. Plunger, Burger Button—The button is a device that, when the arrow is being shot, prevents the rear of the arrow from overtaking the front. It also aligns the arrow in the center of the bow and keeps it from hitting the bow once shot.


Bow plunger

SightThe sight can come in many forms, but the most usual ones would be a circle with a cross-hairs or pin at its center. Some compound bows incorporate a "spirit level" which tells the archer if his or her bow is tilted.

Bow sight

ClickerUsed only with the recurve bow, this device tells the archer when he or she has pulled the bow a certain distance. This helps the archer know when the string is pulled back far enough to fire, as too far or too short a pull will not produce an accurate shot.

LongrodThe longrod is a 2ft extension of the bow which dampens vibration produced by the shot, and also tilts the bow foreword slightly once the shot has been made.

V-bar/StabilizersVarious types of attachments designed to steady the bow when held.   Bow stabilizer

Nocking PointThis can either be a piece of string or a metal clip attached to the bowstring that holds the arrow nock in a fixed place on the bowstring, keeping it from sliding up and down.

SlingThe sling allows the bow to rest in the archer’s hand without having to actually hold the bow.

KisserA nocking point fixed onto the string that rests at the corners of the mouth when the string is pulled back. This is used as a marking point to let the archer know he or she has pulled the string to the same position.

PileThe point of the arrow that goes into the target. Most often a bullet style is used.

NockA clip, usually of plastic, at the rear of the arrow that fits onto the bowstring and nocking point.
 
Two arrow nocks

VanesAlso called the fletching. These three feathers near the rear of the arrow called the shaftment (which includes the nock) keep the arrow on course. The
feather is set at a right angle to the nock. Vanes can be made of plastic but some longbow archers use real feathers, such as turkey feathers.
 
Arrow vanes

ShaftThe shaft is the long, middle part of the arrow that connects all the parts together. Longbow arrow shafts are made of wood, while recurve and compound
arrow shafts are made from either aluminum or carbon. Aluminum is heavier but cheap, while carbon is lighter, expensive, and very fragile. It is best for beginners to
start with wood, go to aluminum, then to carbon.

Arm GuardThis piece fits over the bow arm, keeping the string from coming in contact with your arm when the string is released.   Arm Guard

Chest GuardProtects the chest and keeps loose clothing from getting caught by the string.

Finger TabThese are used to protect the fingers while drawing the bow. Compound archers use a release aid which is a device that fixes onto the string, and is used to pull it back without the fingers in contact with the string. A release button lets the arrow fly. This is similar to the Mongolian thumb rings which work to the same purpose.   Finger tabs

StringerRecurve archers use this device to string their bows. Compound bows are permanently strung and many longbows have built in stringers.   Stringer

Arrow StraightenerSometimes arrows can be bent, like aluminum arrows. This device straightens them out. A dial measures how bent your arrow is and a plunger pushes against the bend to straighten it.

You, the Archer
     
     Any experienced archer will recommend that you start out with quality equipment. Cheap bows and arrows may be unreliable, poorly constructed, inaccurate, and could even injure someone. Most dealers in sports equipment carry quality, if expensive, merchandise.

     Choosing the right bow is very important, since bows can be as individual as the archers themselves. It must not have too large a draw weight or be too long or short or you are apt to pull a muscle. Arrows depend on the type of bow, so they should be chosen after the bow. Particularly long bows with large draw weights require long arrows, and shorter bows need correspondingly short arrows.

     As for draw weight, it is advised that beginners start out with 15-20 lb. because the lighter it is, the more focus the archer can put on proper technique. However, such a light draw will not have a great range. Once the archer has mastered the basic skills, he or she may progress to a more powerful and heavy bow.

     It is always important to have proper instruction when learning a new skill. An instructor will help you select the right bow, and keep you on track with posture and technique. Learning safety is extremely important because a loaded bow is as dangerous as a loaded gun.
