APEXEL 1200m Golf Laser Infrared Telescope Rangefinder 1. Functions: distance measurement, speed measurement, height measurement, angle measurement, golf trajectory correction, flagpole lock, smoke 2. While clearly observing the object, the distance between the fixed object and the moving object can be measured within a certain range. 3. High ranging accuracy, short ranging time, intuitive distance display, low power consumption, self-powered. 4. Adopt eye-safe 905nm laser emission tube and high-performance optical components. No need to cooperate with the target, can measure the distance of any target. 5. Small size, light weight and easy to carry. 6. Can be widely used in surveying and mapping, security, outdoor, golf courses, environmental protection forestry and many other fields. parameter: 1. Distance range: 5-1200M 2.
