You all know that I bought that brand new Reflex Highlander compound bow recently... That bow is absolutely WICKED!
Anyway, I just upgraded the sights on it and with my being a lefty, I ordered a left handed pendulum sight from Vital Bow Gear. This thing is really cool!! You turn the lever on the top/back and it locks the swinging pendulum, so you can shoot/practice on flat ground. But when you're in a treestand, you unlock the pendulum, and it automatically compensates for any distance from 5 yards to 30 yards, without any guess work!!
