A Xero sight ranges the target and lights a single LED pin at the exact distance, so there is no gap-guessing between fixed pins. You press a silent trigger on the grip, the Class 1 laser reads the range — up to 100 yards on game, 300 on reflective targets — and the pin appears where the arrow will go, already corrected for the angle of the shot. No visible light is ever projected toward the animal.
A1 gives you red pins and the core auto-ranging behaviour. A1i adds a second pin colour (green), an electronic level, multiple arrow profiles, shot dynamics and Laser Locate, which drops a waypoint at the shot location and pushes it to a compatible Garmin GPS device for the recovery. A1i PRO builds on A1i with micro-adjustable rails, a quick-detach mount, auto calibration, a dynamic level, a flight pin and Xtra Distance mode for shots beyond the sight’s normal range.
All three run on two AAA lithium batteries with a stated year of life, are IPX7 rated, and operate from -20°C to 60°C. Pick the handedness to match your bow. Batteries are included with the A1i PRO and sold separately for A1 and A1i.
