With an 1800m maximum range and a built-in ballistics computer, the GSeven BR2 Ballistic Rangefinder is ideal for long range shooting situations. 7X magnification brings your target into clear view for accurate calculations. Programmable for up to five ballistic profiles according to your muzzle velocity, sight height, ballistic coefficient and zero range. Inclinometer measures the shot angle, while an integrated weather station measures temperature and atmospheric pressure to ensure accuracy at incredible distances. Select a firing-solution readout between BDC, Mrad or cm. Sync the rangefinder to your exact ballistics with BDC mode by inputting the altitude and temperature that the turret or reticle was built to match so the computer can automatically calculate adjustments based on current conditions for you. Four targeting modes (nearest target, farthest target, strongest target, and continuous range) enhance detection in tough light or weather conditions..
