I had a dropzone on my trykon for a total of 3 days and realized it was junk on a Tek Riser. You have to wrap the chord around the bridge on the riser and it rubs. This caused my rest to start hanging up and not dropping. I think it might be fine for any other bow without the tec riser. I made a 100.00 mistake. and now i have a dropzone in my junk closet. I went back to my muzzy zero effect, stupid for ever trying anything else.
