I have an older Predator IV pendulum sight. If somone wants to try it out. I spend more time on the ground huntin' ground hogs and stump shooting and this year am moving towards a recurve. And when I am up a tree. I have never had a reason to go highter the 16' or so. If you want to try it out, let me know and I will send it to you. It is just sitting in my gear box.
