A stabilizer is a rod, usually made of carbon, with threads on both ends. One end of the stabilizer screws into the bow and the other lets archers customize their bow’s balance by adding or removing weights. Stabilizers help archers hold their bow more stable while aiming, thus increasing their accuracy and consistency.
To understand what stabilizers do, hold a long stick (or a broom handle) at arm’s length and move your hand around. Notice how its tip moves slower than your hand, and wants to stay in the same spot? It’s resisting your hand movements. By attaching a stabilizer to your bow, you help the bow resist your shaking. The more weight at the stabilizer’s end, the more it resists the archer’s movements.
Even so, be careful. If you add too much weight to the stabilizer’s end, the bow becomes less stable as you start struggling to hold it up.
Archers have many brands of stabilizers to choose from, but target archers usually start with one 26 to 30 inches long. The longer the stabilizer, the heavier the weight at its end will feel.
Mount the stabilizer to the bow and add weights to its end. Add enough that it’s easier to aim, but not so many that you struggle to hold up the bow.
Warning: Stabilizer companies use different thread sizes on their weights and ends. When buying weights for your stabilizer, make sure their thread sizes match. If they don’t, you won’t be able to attach them to your stabilizer!
