Release Checker & Training Aid Firing-Line is the ultimate training tool for archers. The L model has a draw weight of 10 to 12 pounds. So compact, it stows in a brief case...perfect for practicing anywhere, anytime. With quick draw-length adjustment, its great for warming up, tuning a release or muscles. Even better, it can overcome everyone's nemesis...target panic. Never worry about throwing an arrow...just aim and practice the perfect release, time-after-time. With each smooth and quiet shot you burn-in muscle memory so when its the real thing, you burn-in the x-ring. Adjusts from 32 3/8 inch to 24 inch draw length by positioning the handle. Now with the new optional weight set its even better. Clip on three pounds of weight...close your eyes, draw and fire...you'll swear it's a real bow and so will your muscles. Firing-Line...The place to practice.
