Designed to improve a shooter’s accuracy and maximize precision out to 100-yards, the 2-7×36 variable speed scope accommodates the fastest of crossbows shooting between 380-505 FPS. The scope’s upgraded glass provides the shooter with improved image clarity and brightness, allowing for maximum long-range accuracy. In addition, the scope's calibration process is simple and intuitive: sight in at 20 yards then verify and micro-tune at 50 yards, after that the scope is zeroed at 100 yards. Custom 100-yard reticle eliminates scope clutter to enhance downrange precision: Three illuminated dots calibrated at 20-, 30-, and 40-yardsThree illuminated crosshairs at 50-, 60-, and 70-yardsThree illuminated chevrons at 80-, 90-, and 100-yards.
