I love them, I'll go to one whenever I can. I use my hunting rig, same draw weight and everything, it really helps me get ready for hunting. I use my rangefinder as well, but only after the shot to see how close I estimated and to help dial my eye in. I definitely encourage you to go. Even if you feel retarded at your first one there will be plenty of folks who will walk you through it and help you. Just remember, you're only competing against your own worst enemy, yourself.
