The Xero X1i crossbow scope is an industry first with its 3.5x magnification and integrated laser rangefinder. This state-of-the-art product allows shooters to shoulder the crossbow, identify the target and receive ranging information at the touch of a button. Precise illuminated aim points automatically adjust brightness and allow you to see your target, unobstructed by reticle patterns. The Laser Locate waypoint projection works with compatible Garmin devices to show you exactly where the target was located when the shot or range was taken, making it easier to track game or find bolts. Create custom bolt profiles with unique aim point stacks for accurate shooting across a variety of setups. A digital bubble level helps avoid tilting the bow left or right, Steady Aim technology lets you know how well you are holding on target, and a Flight Apex indicator shots the highest point your bolt will reach, helping you avoid tree limbs or other obstacles. The Xero X1i is built with an aluminum housing and is IPX7 waterproof rated. Features premium, fully multicoated, nitrogen-filed optics. This scope is designed for attachment to Picatinny or Weaver rails via the included screws. Powered by two AAA lithium batteries that power the optic for up to a year.
