Ravin Crossbows Xero X1i Features The Ravin Xero X1i developed by Garmin is customized exclusively for Ravin crossbow models including the R9 R10 R15 R20 R26 R29 R5X R10X R26X R29X and R500. Precise digital aimpoints are pre-calibrated for each of these models so hunters simply select their Ravin crossbow and sight in at 20 yards rather than working through a lengthy manual zeroing process. A built in electronic level sensor provides angle compensation correcting for uphill and downhill shot angles that can otherwise throw off arrow placement from a tree stand or elevated blind. The scope also features a Ravin custom colored reticle designed for fast clear target acquisition in the field. Reticle brightness is controlled through an ambient or manual light sensor automatically adjusting to changing light conditions throughout a hunt or allowing the hunter to set it manually as needed. At 3.5x magnification and a compact 6.2 by 2.6 by 3.7 inch footprint the Xero X1i stays lightweight at 1.9 pounds while still delivering a clear usable sight picture. The 1.2 inch display keeps aimpoint information visible without cluttering the sight picture. Powered by 2 included AAA lithium batteries the Ravin Xero X1i Integrated Crossbow Scope by Garmin is available for sale at GrabAGun for Ravin crossbow owners seeking fast accurate sight-in and shot placement.
