The G7 BR2 Rangefinder is the only rangefinder that ranges and calculates your ballistic solution for any shooting condition. Here’s how it works. The rangefinder is programmed for several ballistic parameters that are unique to your cartridge and firearm. Ballistic Coefficient, Muzzle Velocity, Sight Height and Zero Range are easily programmed on the device using the four input buttons. When selecting the MOA output mode no other inputs are required. If you are using a ballistic turret or reticle calibrated in yards, the BDC mode is selected and additional inputs for the Altitude and Temperature that the turret or reticle was built to match are entered. The device also calculates the exact wind hold solution based on your air density and shot angle. Just press a button and scroll through the wind correction in MOA in five mile per hour increments. The wind display calculation is our own patented technology and completes the ballistic solution. Another unique feature is four distinct targeting modes that enhance target detection in tough light conditions and unsurpassed ranging in rain, snow, and fog. The targeting modes are Nearest Target, Farthest Target, Strongest Target, and Continuous (scan) Ranging. It has never been easier to range an Elk on a slope of burnt timber, or Pronghorn on the rolling plains, or Coyotes on a snow covered field. Specifications:? Functional Range: 1500 yds.?
