The universal rope cocking device is an absolute must for every crossbow owner. The device uses leverage to produce a 50% reduction in draw weight. It doesn't matter how strong you are, if you use a rope cocking device you will see an immediate increase in accuracy due to the consistency in cocking the bow straight by eliminating off center string alignment. It just doesnâ€™t make sense to do it any other way, whether you need it or not. Get a rope device and improve your shooting.
