Ive got the new Summit Hot Dot pendulum sight. It works AWESOME. Its all electronic which is the only thing im worried about. Dont want that battery goin dead when I finally draw back on a monster. All you do is sight it in for 30 yards from the ground with a fixed pin (led). Switch it to pendulum and you are right on from 0-30yards from 10-30ft in the air. The great thing about it is that there is only one red dot and the rest of the sight is wide open. It allows you to see the deer and there arent any pins in the way. Its a great sight
