I'm sorry to hear you are having the same problem my wife had with the Trophy Ridge bow sight!

She shoots a Hoyt Selena, to get it sighted in we had to drop the TR so low a broad head was dangerously close to hitting the botton of the TR sight!

So we both switched to the TruGlo Brite-Site Extreme and are now very satisfied with the TruGlo a year later.

I have two very expensive Trophy Ridge sights that are just sitting in a box doing nothing! The one I had moved to the left after a couple dozen shots, I could never get it tight enough to keep the sight from moving.....so I just gave up.....besides the up-right pins seemed to disappear in in bright sunlight.[:@]
