The Universal Rope Cocking Device is an absolute must for every crossbow owner - PERIOD. 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 doesn’t make sense to do it any other way, whether you NEED it or not! Get a rope device and improve your shooting.
