ARROW WILL NOT FALL OFF RESTWhether stalking, drawing, or slowly letting down, the Ultra-Rest is working (full time) to totally support and capture the arrow. VDT (Velocity Drop-Away Technology)This patented feature allows the UL?TRA-REST to fall away only when the bow is fired.SUPER QUIET AND DURABLEPrecision machined aluminum components, internal silicone bumpers and laser cut felt offer superior noise reduction.SHOOT SHORTER ARROWS / INCREASE SPEEDOffers minimal friction and zero fletching contact. Also allows you to shoot the shortest arrow possible (Up to 4" shorter.)ARROW WILL NOT DRAG ACROSS THE BOW SHELFThe ULTRA-REST is cocked into the verti?cal-ready position via the thumb wheel providing 360 degree arrow capture, assuring total bow shelf clearance when drawing or letting down. Unlike other rests that drop-away because of inertia or vibration the ULTRA REST relies on the velocity of the forward movement to initiate the launcher to drop. VDT assures that the ULTRA-REST remains in the cocked position even on a slow let down, and will only drop-away if the bow is fired. VDT is a durable and reliable firing mechanism which is sure to change the way you look at drop away rests.
