Being advance in age, I mounted one on my bow a couple of years back, I couldn't see the pin clearly enough. I love it, you can adjust the dot intensity to match the light condition plus don't need a pin light. The scope is a BSA 30mm red dot mounted on 3-D fieldmaster Sight bracket that allows for range adjustment. The batteries last me the whole season 2 months of hunting with the sight on 3+ hrs a trip.

Love it.
