An arrow rest is a device used in archery to support an arrow before it is shot. It helps to stabilize the arrow and ensures proper alignment with the bowstring, improving accuracy. Arrow rests come in various types, including drop-away, whisker biscuit, and plunger rests, each designed for different shooting styles and preferences. Using an arrow rest can enhance a shooter's performance by reducing the chances of the arrow falling off the bow during the draw. Properly selecting and adjusting an arrow rest is essential for achieving optimal results in both target shooting and hunting scenarios.
