After a lot of research I decided on this particular sight. Main reason, I didn't like the post sight and it blocked too much of the area around it. This looked like a better option. I have a 20 year old Hoyt bow. A decent introduction into the hobby and began to upgrade the older components. It was a tough fit, there are two sets of mounting holes. I could only fit it in one set. Be wary of this if you have an older bow. The vertical adjustments are a pain. Two screws and a nut fasten the sight for the vertical adjustment. On mine I had to unscrew the screws to adjust then replace the nuts and screw the screws back into place. The screws are right up against the frame. I ended up taking to a local LEO friendly shop and they helped me get the adjustments right. Because the bow could only mount on the upper most mounting holes it was close and I couldn't lower the sight anymore. The variable lights to the sight are awesome and you can adjust on the fly. Even with all the initial problems I would still buy it again. Or later when I upgrade the bow use the same sight. I totally recommend this product.
