Feature: 1. Distance Measurement: While observing objects clearly, this telescope can measure the distance between fixed or slow moving objects within a certain range. And in speed measurement mode, the telescope can catch target speed in real time. 2. Accurate Measurement: The telescope has the advantages of accurate measurement, short ranging time, intuitive distance display, low power consumption and automatic power failure. 3. Universal: The laser emission power of the instrument is small and safe for human eyes. The telescope does not need to pair targets, and can range any target. 4. Easy Carrying: Comes with small sizes and lightweight, this telescope is easy to store and carry for use at any time. 5. Wide Application: The telescope is widely used in electric equipment installation, wire, wire tower, expressway, municipal engineering, forestry survey and design, building construction, network planning survey and design, communication maintenance and other surveys.
