What the bow does immediately after the shot it was beginning to do during the shot. That, in a nutshell, is why proper bow balance is so important. Perfect stability occurs when nothing moves during or after the shot. Though you’ll never get the limbs and cams to remain stationary, you can and should control the position and movement of the riser until the arrow is firmly in the target.
After the shot, the bow should ideally rest in your relaxed hand in exactly the same position it occupied while you were aiming. This is a good indication that the bow is well balanced and that you made no effort to manipulate the grip during the shot. In other words, you did what you were supposed to do: you let the bow shoot the arrow.
Your bow shouldn’t tip forward, back, left or right. To achieve perfect balance, the bow must either be designed that way at the factory or you need to apply the proper amount of weight in the right places. But, first you need to find out what your bow is doing during the shot.
TESTING YOUR BOW’S BALANCE
Generally, deflexed riser bows will tend to tip back toward the archer and reflexed riser bows will stand more vertical in the hand. But it pays to find out exactly what your bow does because every one is slightly different, depending on the accessories attached. Start by making a wrist sling that isn’t connected to the bow. This is the best way to let the bow move freely. Tie a piece of light rope or twine around your wrist, wrap it around the front of the grip section of the riser and then tie it back onto itself on the other side of your wrist.
Stand three feet from a blank backstop and shoot arrows while focusing on keeping your bow hand very relaxed until well after the arrow has hit the target. If you are accustomed to shooting with a tense hand it may be difficult for you to tell if your grip is relaxed. Have someone try to move your fingers while you are at full draw. They should move very easily. I can stay more relaxed during the shot by closing my eyes. If you decide to do this, ask a buddy or spouse to watch the bow and tell you which way it tips just after the arrow leaves. Make no effort to keep it upright with your wrist; just keep your hand and wrist totally relaxed and let it fall where it will.
If you will be using a bow quiver full of arrows, then be sure the quiver and arrows are attached when you’re testing your bow. As you can well imagine, the quiver will have a big affect on your bow’s overall balance.
CHANGING YOUR BOW’S BALANCE
After learning how your bow behaves during the shot you can take steps to balance it. Most of my Hoyt bows are well balanced. For example, I don’t apply any significant weight to them for hunting – just a short Sims Enhancer stabilizer to reduce vibration. But, many bows require some weighting, and regardless of bow design all will need a counterweight if you want to completely balance a bow quiver.
The easiest bow to balance is the one that tips backward during the release. You merely add conventional front-mounted stabilizer weight until the bow balances. Modular stabilizers or stabilizers with sliding or variable weights make this easier. You may also be able to perform this test in the archery shop by trying stabilizers of different weights until you find the one that keeps the bow upright.
If the bow tips forward without a stabilizer attached it becomes more difficult to achieve perfect balance. Some good archers prefer this type of balance, and I would agree it is definitely better than a bow that tips back. But personally, I want my bows to stay level. There are two ways to balance this bow: adding back weight to the riser or reducing the weight of the sight.
Some risers - those from Mathews come to mind - have a threaded hole bushing below the grip on the back of the riser - an extension of the normal stabilizer hole - where you can attach a short stabilizer for back weight. For 3-D or target shooting you can also use a V-bar system available from most stabilizer companies in conjunction with a front-mount stabilizer hole to move weight back, but they are too cumbersome for hunting. Finally, if you are using a heavy sight, a lighter model with a shorter extension bar will also help.
Many bowhunters use bow-mounted quivers but few weight their bows to counter-balance them. Unless you sight-in and practice with the quiver attached you will notice a slight change in impact point when you attach it. I don’t count this as critical, but if you are looking for perfect balance you need to counter-balance the quiver. Fill it with arrows and use an offset stabilizer bracket (most stabilizer companies offer one) or a set of balancing weights from specialty companies like Golden Key Futura.
Bow balance may be a secondary concern when setting up a bow, but when you consider that success and failure in the field and on the range often comes down to fractions of an inch, everything counts. Take the steps to balance your bow and enjoy better accuracy.
