Revic BR4 Ballistic Rangefinder Black/Orange. These Range Finders by Gunwerks utilize a single-pulse ignitometer to measure the distances (in feet meters yards or meters) to a target along with precise angles (ranging) which will allow you to either shoot to range the target or simply know the distance and the shoot-to-range value. The range of the Gunwerks Revic BR4 10x Laser Rangefinder is measured in meters and the dual-rangefinder model reads out in yards providing fast target distances. For long-range targets the rangefinder will display a compensated range which will compensate for drag and wind drift. In addition the rangefinder temperature can be measured and the inclinometer will tell you the degree of elevation change. The Gunwerks Revic BR4 is Bluetooth-enabled with the Gunwerks app so that you can update the rangefinder software directly when new software is released.
