Choosing a New Compound Bow by Steve Peters
There are many different types of bows on the market today, but choosing one is not an easy undertaking. The bow-manufacturing industry has been flooded with new innovations and developments in the last decade. Compound bows have gone through many alterations in appearance and architecture, with a number of drastic changes occurring in the past few years. Justifying the purchase of one bow over another these days requires more than just a large wallet filled with greenbacks and plastic. Fortunately, there are a few guidelines and procedures to follow that will help simplify the process.
Choosing the latest advancement in primitive weaponry begins with a decision to shoot a certain type and brand of bow. Draw length, draw weight, accuracy, wheel and cam design, reflex and deflex riser geometry, brace height, let-off, speed and price are all things to take into account when selecting a particular bow. Other factors to consider are its use. Will it be a hunting bow or a target bow? Will the majority of your shooting be indoors or out? Will it require a camouflage finish or not?
Once you have come to these conclusions, the next step is to visit a local pro shop or surf a favorite web site to obtain more information. A bow must "fit" its shooter. Having a qualified individual measure your draw length is the most important aspect of deciding to purchase a particular bow. Most bows offer multiple draw length options and adjustments.
Draw weight is yet another matter of importance. Draw weights are also adjustable and allow for various settings in 3- to 5-pound increasing and decreasing increments. Peak draw weights normally range between 45 and 90 pounds. Taking the time to shoot several bows will provide answers and can help determine the significance of each of the aforementioned considerations. It's wise to test shoot as many bows as possible before laying down your hard-earned cash.
The current trend in manufacturing designs is to create bows with short axle-to-axle dimensions, reduced mass weight, low brace heights and high let-offs. Many companies have shied away from producing bows that feature round wheels, moderate let-offs or measure over 40 inches from axle-to-axle. This is in direct result of the present demand for more compact bows that possess the ability to boost arrow velocities, increase kinetic energy levels and extend downrange efficiency.
Of all the different makes and models of bows in existence, compounds certainly offer the widest variety of choices for today's archer. Single-cam string and cable harness configurations, split limbs and ultramodern risers forged from high strength multi-composite alloys are just a few of the available upgrades in current production.
There are many advantages to owning a bow with a contemporary look and feel. As mentioned previously, split-limb and single-cam models significantly reduce mass weight. This quality is beneficial to those adventurous hunters who hike into remote backcountry in search of elk and mule deer. Also, in comparison to their two-cam and two-wheel counterparts, single-cam bows are relatively easier to tune and maintain.
In addition, the lightweight aluminum and carbon material used in the limbs, handles and risers, and the fabric used in the strings and cables of new age bows contribute to overall speed and weight reduction. If speed and weight reduction are the determining factors, choose your bow accordingly. These types of bows are better suited to those who utilize a release due to the sharp angle created in the string when a short-limbed bow is fully drawn.
On the other side of the equation, longer axle-to-axle bows are more accurate and forgiving, although this trend is starting to change with ongoing improvements in bow design. If the main concern is supreme accuracy, choose a bow that offers a longer brace height, a riser with deflex geometry, a moderate to low let-off and as long an axle-to-axle length as possible. Deflex risers generally reduce hand torque and are normally found on the most accurate bows. A low to moderate let-off will also yield more accuracy. Those who shoot with a finger tab or a glove require bows that create less of an angle in the string at full draw. This will greatly reduce accuracy problems associated with "string pinch," which occurs at full draw when an acute angle in the bowstring causes extreme tension on the arrow.
Compound bows have one distinct advantage over all other bows -- let-off. Let-off is measured by a percentage of the draw weight that is reduced when the wheels or cams roll over at or near full draw. During this process, a fraction of the peak draw weight is decreased or "let-off."
The amount of let-off will not only affect accuracy, but also the personal satisfaction of the shooter, and quite possibly, trophy-book consideration. Much controversy has arisen from the limitations that the Pope and Young Club has placed on the amount of let-off a bow can possess. Sixty-five percent is the cut-off point. Any amount of let-off over 65 percent disqualifies an animal from being entered into the archery record book. Some bows offer higher let-offs in the 75- to 80-percent range. Be aware that a legitimately harvested trophy may not be eligible for record book recognition if the bow you choose has a let-off that is prohibited by the club.
Note: The Pope and Young Club currently lists animals taken with bows having a higher let-off than 65 percent. An asterisk is placed next to the name of the individual who harvested the animal. The asterisk denotes that a bow with a higher let-off than 65 percent was used to harvest the animal.
Limb selection is no longer limited to solid one-piece models. The appearance and performance of bows changed dramatically with the inception of split limbs. However, both types of limbs have advantages and disadvantages. Solid fiberglass and carbon limbs are inherently more durable than two-piece limbs. Nevertheless, split limbs not only reduce weight, but also transfer and distribute energy from the bow to the arrow more evenly. Some archers appreciate the appeal of a split-limb bow while others favor the traditional shape of solid limbs. The option of choosing straight limbs or recurved limbs is also available on most bows in production today. Straight limbs are generally faster while recurved limbs are more forgiving. With the overall differences minimal in comparison, personal preference normally plays the biggest role in limb selection.
These are just a few examples of what state-of-the-art engineering has to offer in bow design. It also illustrates the dilemma one will face when attempting to reach a final decision on which model to purchase. Only research and a healthy amount of leg and arm work will assist an archer in the quest for choosing the "right" bow.

SELECTING THE RIGHT COMPOUND BOW
Have you ever asked yourself the question, which bow should I get, or which bow best fits me? Well we have! Here at Pick a Spot Archery we want to help you narrow down that “big” decision on selecting the right compound bow. We know that that decision could very well be the difference between hitting the spot or a total miss (between dead or alive). Like every other product on the market today, compound bows come in a vast variety of brands, shapes, colors, sizes, and levels of difficulty. If you’re an archer of heart, or a new beginner, Pick a Spot Archery wants to help you through the process and steps on selecting your next bow and making that “big” decision.
Type of Bow
1- In the world of compound bows, there are two main types. The first type is a two-cam (or dual cam). The two-cam system features two perfectly symmetrical round or elliptical cams on each end of the bow. The other type is referred to or known as a single-cam bow (or solo cam). This type of bow has a round wheel on the top (which is called the idler wheel) and a wheel on the bottom which is called the cam (or round wheel). The bow in the illustration is a single-cam bow, as you can see it has round wheel on top and a power cam on the bottom. Choosing between the two types of compound bows is what we consider the first step. Everyone has their own personal beliefs and input on which cam system is the “best”. Here at Pick a Spot Archery we take pride in saying single-cam bows are “the best” and our preference of choice. If you haven’t noticed we only sell single cam compound bows. Why? These are our reasons of belief.
- More efficient
- Tend to be faster
- More accurate
- More forgiving
- Less maintenance
- Less noise
- Less recoil, vibration
- No synchronization problems
Price
2- Once you have narrowed your choice down to the type of bow, it would then be smart to ask yourself, how much money do I have or want to spend? A good compound bow generally ranges $300-$700. The price difference is usually broke down to the material make of the bow. Just like an engine and leather seats can be to a car. The price can also be broke down to the basic simplicity of the bow itself. For example a youth/women’s bow tends to run a lot cheaper than say a bow made for power and speed.
Determining Draw length
3- The next step in choosing the right bow we will call, determining the draw Length. Unlike a traditional recurve bow that can be drawn back to virtually any length, a compound bow will braw back only at a specific distance before it stops. Compound bows are made to shoot at full-draw position. To be able to shoot at full draw, one will need to know what his/her draw length is. Determining your “draw Length” is very important for proper shooting. The length must fit your arm length and is definitely essential in purchasing a compound bow. There are two methods for one to find his/her draw length.
1. The first and probably the most accurate are to measure your wingspan. Hold your arms straight out and measure from finger tip to finger tip. Round off to the nearest inch.
- 63" Wingspan = 24" Draw Length
- 64" Wingspan = 24 1/2" Draw Length
- 65" Wingspan = 25" Draw Length
- 66" Wingspan = 25 1/2" Draw Length
- 67" Wingspan = 26" Draw Length
- 68" Wingspan = 26 1/2" Draw Length
- 69" Wingspan = 27" Draw Length
- 70" Wingspan = 27 1/2" Draw Length
- 71" Wingspan = 28" Draw Length
- 72" Wingspan = 28 1/2" Draw Length
- 73" Wingspan = 29" Draw Length
- 74" Wingspan = 29 1/2" Draw Length
- 75" Wingspan = 30" Draw Length
- 76" Wingspan = 30 1/2" Draw Length
- 77" Wingspan = 31" Draw Length
2. The second way of determining is as follows. Make a fist with your bow hand and touch it against a wall straight out to the side of your body as if you were shooting a bow. While you stand straight, in a good shooting posture, have someone measure the distance from the wall to the corner of your mouth.
Determining your Draw Weight
4- In determining your draw weight it will mostly depend on your stature and strength. The best thing to do is to start out light when shooting. Choose a weight that is easy to draw so you can build your muscles after repeated shooting. The chart below will give you an idea of what weight would be typical. Also keep in mind that if you are using your bow for hunting there will be certain restrictions on what weight is required for hunting.
Here are some general guidelines for choosing an appropriate draw weight. Of course, each individual is different. You should apply your common sense here and interpret these numbers with due respect to your own age, general physical condition, and Body Mass Index (BMI). Very Small Child (55-70 lbs.) 10-15 lbs. Small Child (70-100 lbs.) 15-25 lbs. Larger Child (100-130 lbs.) 25-35 lbs. Small Frame Women (100-130 lbs.) 25-35 lbs. Medium Frame Women (130-160 lbs) 30-40 lbs. Athletic Older Child (Boys 130-150 lbs.) 40-50 lbs. Small Frame Men (120-150 lbs.) 45-55 lbs. Large Frame Women (160+ lbs.) 45-55 lbs. Medium Frame Men (150-180 lbs.) 55-65 lbs. Large Frame Men (180+ lbs.) 65-75 lbs.
Final Decision
One of the best things you can do is to visit an archery shop and shoot a few bows to see which one feels the best and is most to your liking. Once you have determined on a bow that fits you to your liking, you will then need to fit the bow up with accessories (arrow rest, pins/sights, peeps, etc.). At Pick a Spot Archery we take pride in our selection of compound bows, and hope that you make one of ours your final decision and always remember aim small, miss small!
