Introduction  This product is based on a 905nm pulsed laser, a laser semiconductor transmitter and receiver Paul binoculars developed by TOF principle. It can obtain high-transmission stereo images while achieving multi-functions such as long-distance distance measurement, height measurement and angle measurement, And it build-in electronic compass that could measure real-time azimuth. The product has high accuracy. It has many functions, is portable and easy to operate. It can be used for measurement in a variety of complex environments.  Feature  1 The product adopts the design of the classic nautical Paul telescope, and the lens adopts high-definition coating, which can clearly observe the target from a long distance. 2 Using a High transparency LCD display , does not block any observation field of view; 3 Data can be obtained quickly within 1 second, regardless of distance; 4 The product adds an electronic compass, which can obtain the real-time position of the observation target.  Specification  1) Binocular + Range finder 2) Electronic Compass, obtain the real-time position of the target 3) Measurement error: ±1m(1-600m)/±2m(1-1000m)/ ±3m(1-3000m) 4) 1000yard laser Rangefinder(Meter or Yard) 5) 8x Lens Magnification( Fixed) 6) 40mm FMC Lens Diameter 7) 20mm Eyepiece 8) Laser band: 905nm 9) Dustproof & Waterproof IP65 10) 3v CR2 Li battery(Included) 11) Range Measure, Height Measure, Angle Measure and Compass 12) Adjustable Pupillary Distance: 56mm to 72mm 13) Laser band: 905nm 14) Security Level: Class 1 15) Dioptre: ±5 degree 16) Net Weight: 933g 17) Gross Weight: 1.3kg/pc 18) Giftbox Size: 175(L)*210(W)*85mm(H) 19) Optical Resolution: 11     Ranging restriction statement  This range-finding telescope is suitable for measuring high-reflectivity objects (such as highway signs) in reflectivity objects (such as low-reflectivity objects on building walls (such as trees and golf flagpoles). When the reflectivity drops to a certain level, the range will change Reduce accordingly. 1. The measurement target has a medium reflectivity: such as the wall of a building;  2. The reflection surface of the measurement target is perpendicular to the laser emission direction. 3. Measure the weather as clear but not under direct sunlight as much as possible 4. The area of the reflecting surface of the target as far and close as possible (>400m) is not less than 2m*2m
