The Garmin XERO X1i Rangefinding Scope was designed for use on crossbows and comes packed with features directly out of the box. This advanced optic is equipped with an integrated laser rangefinder and can accurately measure angle-compensated target distances up to 250 yards away. The XERO X1i also allows the user to create custom bolt profiles for more accurate shooting across a wide array of different setups. Other functions of the Garmin XERO X1i include the Laser Locate function, which marks where your shot was taken and sends the data to a compatible Garmin GPS device (sold separately). The user can then use this to create waypoints and help track downed game. In addition, the XERO X1i features a durable design to stand up to the worst possible conditions, and is outfitted with high-performance optics for superior visibility in low light conditions and excellent edge-to-edge clarity.
