Know the range, and shoot the exact pin with minimal movement using xero A1 Bow sight. It’s the first bow-mounted digital laser range finder and targeting display system that measures the angle-compensated distance to your target and provides an LED pin for the shot, even on those “in-between” yardages. LED pins automatically adjust brightness to conditions and allow you to see your target, unobstructed by physical pins. A single-button trigger lets you range at rest or full draw to game up to 100 yards away or to reflective targets up to 300 yards. Zero A1 is customizable for single-pin and multi-pin configurations or for Manual pin selection.
