I've never used a clicker, but we do have some people here who do junior shooting programs that feature Oly recurve. This kid (teenager) was supposedly pretty good (he was a 59 or 60x shooter later with compounds). He apparently had become pretty conditioned to shooting on the sound of the clicker at that point. I had no idea that it could be conditioned that deeply back then, but the guy who owned the shop did know something about it and I think dropped the screw, knife, whatever, on purpose because he suspected what would happen. It sure popped some eyes when he let it go, I'll tell you! The owner did make sure he was aiming at a bare wall at time, thankfully.
