Focus Track has outstanding optics with a 6x magnification, 21 mm focal length and BaK-4 prisms which, together with the advanced multi-layer anti-reflective coating (FMC) gives a precise, clear image even in difficult light conditions. The eyepiece has an eye relief of 15mm, which makes it easy to use even if you are wearing glasses.The rangefinder comes in a compact format and is easy to use with one hand. An all-weather and dust resistant, durable body makes it is perfect for carrying while golfing, hiking or hunting, or for measuring and surveying without adding extra weight or bulk.The rangefinder is also equipped with a button to turn off protractor functions so you can also use it at golf competitions.Measurement is done with a simple push of a button and the rangefinder has six different measurement programs for different scenarios: Standard mode Measures the straight line of sight to the object. Golf mode Measures the distance to the nearest target. Golf slope Shows the calculated distance in a slope. Great for uphill and downhill shots. Speed mode Measures how fast an object is moving. Max speed 300 km/h. Horizontal distance mode Calculates the horizontal distance to the object and the angle. Makes it easier when aiming downhill. The display alternately shows the distance and the angle. Vertical height mode Aim for the base of an object, e.g. a tree or a building, and then towards the top. The display now shows its height.The range finder has an built-in Li-ion battery and is easily charged via Usb-C.
