Great little tool for working on your shot. I randomly set the timer, draw the bow to anchor and wait for the ring. I call it the tinging clicker. After a couple of sessions, you'll hold bit more solid. Heck it worked for me, so it could work for anyone. Just to make it clear, I'm just setting to go off in 5-10 seconds.
Great idea!
I use different tactics, shooting with couple friends, i peek when somebody are just nocking the arrow, and i draw then, ill wait with full anchor, and release after,when my buddy has shooted. But after i read your topic, i decided to use my lidle brothers music box, it plays diffrend songs, maybe 5-10sec long ones, and i can play it with my foot. sorry my english :D im from finland eheheh
