The Focus Track RF PRO allows you to measure the angle between the horizon and the measuring point, and can indicate the horizontal distance (angle-corrected distance) and height to the target. It is the perfect aid for long-range shooting in various terrains or when you just want to find out the height of a hill or tree! The Focus Track RF PRO has an excellent optical design with 6x magnification, a 21 mm focal length and BaK-4 prisms, which together with the advanced multi-layer anti-reflection coating (FMC) provide a precise and clear image even in difficult lighting conditions. The eyepiece has a 15 mm eye relief, making it easy to use with or without glasses.<CRLF><CRLF>The telescope's viewfinder has seven different modes:<CRLF><CRLF>Standard mode: Measures the direct line of sight to the target.<ol><li>Golf mode: Measures the distance to the nearest target.</li><li>Speed mode: Measures how fast the target is moving.</li><li>Maximum speed 300 km/h.</li><li>Horizontal distance mode: Calculates the horizontal distance to the target and the angle. Makes it easier to aim downhill. The display alternates between the distance and the angle.</li><li>Vertical height mode: Aims at the base of a target, such as a tree or building, and then towards the top. The display now shows its height.</li><li>Area mode: Combines up to two measurements and calculates the area.</li><li>Volume mode: Combines up to three measurements and calculates the volume.</li></ol><CRLF><CRLF>The measurement results are displayed on both the internal and external LCD screens. The external screen displays the measurement results simultaneously. In addition, the Focus Track Pro has a new integrated log function that can store up to 60 measurement results. The rangefinder has a built-in Li-ion battery and is easy to charge via USB-C.
