We recently adjusted the draw length on one of our ProStaffer's bow and had to resight all his pins. He has 20 yard to 60 yard pins. During the 50 and 60 sight in session, he had an 11mph crosswind. Shooting the FOBs allowed him to sight the pins accurately. It was double checked the following day with ZERO wind and they were dead on. This is what made us a believer. The only issue is the FOBs is Lumenoks do not fire when using them and you can't shoot tight groups (you break them off). So, we are working on Fire Nocks as a sponsor and should be fine. We love the FOBs.
