Quality Archery Designs Ultra Rest Drop Away Arrow Rest. QAD's Ultra-Rest is the only drop away rest that works using Velocity Drop-Away Technology (VDT). When hunting, drawing or during slow let down, the arrow remains fully captured. The launcher keeps the arrow in place at all times. The arrow will not slide across the bow shelf. No exposed noisy springs, linkages, rubber tubing, or magnets. Will work with most bows. Eliminates fletching contact. Reduces hand torque effect on arrow flight. Please choose right or left hand.
