Thanks all...Illinois, I just put it on last night for the pic...my bow is paper tuned and I will be doing the sighting in my self. love the concept though...good to 30yds with pendulum and can dial in any yardage after that with the V-drive...will post some pics of my groups when it's all set up...man I hope this thing is as good as advertised, for $149.00, it better be.
