Come on guys, you should know better than put fingernail polish on a rest that is gonna be used for hunting. It chokes me when my wife uses it, I'm sure a deer could smell it a mile away.

Clear Teflon Polish (or also Nail Hardener) has no scent >after it dries<.

I tried both this year, and the Zapper got put in the cabinet to try another time. It actually was harder to tune than the biscuit I thought. I tried them both on 3 different bows. The biscuit holds the arrow better than the zapper, if you brush against something with the zapper it knocks the arrow in between the fingers and makes noise. With the biscuit nothing happens. I also shoot with fingers and it really flies good. I use a release also sometimes and that worked well too. I am getting 266 fps with my Accutec set at 64 lbs and 425 gr arrow at 30". What good is 5 fps if your arrow just fell off your rest? I thought the zapper made more noise than the biscuit too.
