Horizontally mounted anodized aluminum peep sight mounted by splitting the string into just 2 strands. Improved for '07', it features Dual Radius Slotting virtually eliminating string cutting burrs and sharp points. This 7/32" ultra model has an outside diameter of 1/2", and is stringed at 38 degrees for the perfect line up. The super-deuce is the only horizontal peep sight recommended for bows exceeding 70# peak draw weight.
