Hi, I use the Bodoodle Zapper. Works well for me. I had concerns about draw noise so I called Bodoodle. The Gentleman there gave me the advice about using the teflon nail polish. However another tip he mentioned that works for any rest is >CHAPSTICK< When you head out just put a little daub on the rest where the arrow touches and it quiets it right down. (He did not specify any particular flavour.) It's only good for that one shot, but isn't that all you really need in the field?
