Once your arrow is nocked, all it takes is a simple turn of the ThumbWheel to cock the rest in the capture position, securely locking your arrow in place until you take your shot. Velocity Drop-Away Technology coupled with Smart-Rest ensures the launcher will not drop away until the bow is fired. When the string is released, the launcher instantaneously drops away for complete fletching clearance and perfect arrow flight on every shot. Because it offers minimal friction and zero fletching contact, the Ultra-Rest actually increases arrow speed and accuracy. It also accommodates the shortest arrows possible up to 4″ shorter than comparable rests. The cable clamp makes installation and adjustments easy (bow press not required). Made in USA.
