I've used single pin sights for 15 years now
Montana black gold it great. I now have an accutouch which has click adjustments for each distance. I can choose any range from 20-80 yards in 5 yard clicks. Don't even have to look at what I'm doing just count the clicks.

It seems overly adjustable when new, but once set up its pretty darn nice. The first couple months I was on the edge of switching it back to the Montana black gold.

However right now, that it's dialed in I really like it a lot.

On my other bow I have a trijicon which it very nice but way to expensive to be attractive to enough shooters to be popular. I like the nuke pin that is bright all the time without batteries. The dial adjustment broke on me after 2 years. They fixed it free and returned it within 3 weeks. Some screw stripped out in the mechanism so the yardage dial just spun.

I've had many others but that was long ago. These are the three modern or current versions I've used.
