I've used the hind sight for 2 yrs now and like it. It was hard to get used to at first. The hardest thing was getting away from using the 30, 40, etc. pins in the cross hairs. You sight it in with your 20 yard pin and that is the only one you put in the cross hairs. It is almost like shooting with a rifle sight then. You have to sight up or down on the target to allow for the yardage. At first this was very confusing but now it comes with ease.
