I got a pendulum last year. Put it on and could not hit a thing, no pattern what so ever. There was a locking clip on it for when shooting from the ground, but that didn’t seam to help. I don’t know if I didn’t have it set up the right way or what. Any way I could not get it to work played with it about 3 weeks. Put my old sight back on and have no problems now. Now, I am not saying that they don’t do their job, but it just didn’t work for me. Probably operator error.
