No matter how tough the shooting situation, the Gunwerks G7 Rangefinder will measure and calculate your ballistic solution. Easily program the G7 for ballistic coefficient, muzzle velocity, sight height, and zero range. The G7 also calculates exact wind hold solution for your specific air density and shot again. With four distinct target modes: Nearest Target, Farthest Target, Strongest Target, and Continuous Ranging, the G7 guarantees target detection in low light conditions and extreme weather.
