Bear Creek Arsenal Rangefinder provides ballistic solutions out of the box to 1,500 yards and pairs with your smartphone to facilitate setting and data input! The bluetooth function will integrate data input from your smartphone, such as gun type, ammo used, wind speed, temperature, humidity, air pressure, and more to the ballistic chip in the range finder. After obtaining these parameters, the rangefinder can measure the distance in less than a second. The ballistic chip then quickly calculates the trajectory correction value and displays it on the display screen of the rangefinder to tell the shooter the most accurate MOA or MIL values.
