In a game of inches, this is "game over" for whitetails. The RavinA(R) Xero X1i from GarminA(R) is the first Crossbow Scope of its kind with 3.5x magnification, built-in rangefinding, integrated Ravin ballistic info, and digital auto-ranging. Sighting in is quick, easy and automatic: simply mount the Scope, select your specific Ravin crossbow, and sight-in at 20 yards. The Xero's advanced processor does the rest, giving you a usable aimpoint all the way out to 175 yards. Even better, with just the push of a button, you can range game out to 250 yards and reflective targets out to 500 yards. Ranges are displayed on the 1.2" screen, so you never have to worry about carrying a separate rangefinder. The Xero also features Target Lock technology that tells you when the rangefinder is locked on a target with consistent readings. It's a fusion of accuracy and capability unlike anything the world has ever seen. And with extra features like angle compensation, auto/manual reticle brightness, and an integrated level, you'll have all the tools you need to win in a game of inches. 3.5x magnification Ranges game up to 250 yards, 500 yards for reflective target Pre-loaded ballistic data for every Ravin crossbow ever made (except R18 series) Integrated speed settings Automatically generates a single aim point out to 175 yard once you sight-in at 20 yards Custom Ravin reticle with auto & manual brightness control Target Lock technology tells you when the rangefinder is locked on a target with consistent readings Compass and angle update in real time while ranging (will "lock" after ranging is done) Electronic level sensor Runs on (2) AAA lithium batteries (included) Order today!
