While I am waiting to get my QAD repaired, I put on a friends NAP Quicktune Flipper....
what a neat little rest, no string, to timing. now, if you let down it falls out of containment. so I dont think it would work at all for a hunting rest, but a target rest, could work great for that.
you nock an arrow, put it on the arm in the up position, once you come to draw, it is set, then release, it has rubber bumpers/bands that the arrow pushs on to force the arm out of the way,
in order to get it to work on my general, I had to move the arm to a point that the micro adjust knob on the side doesnt make contact, but there is a bolt to tighten it up, worked fine.
