Wavespectrum SNDWAY SW-M80 Laser Distance Meter(80 m) Non-magnetic Engineer's Precision Level  (11 cm)

A laser distance meter emits a pulse of laser at a target. The pulse then reflects off the target and back to the sending device (in this case, a laser distance meter). This "time of flight" principle is based on the fact that laser light travels at a fairly constant speed through the Earth’s atmosphere. Inside the meter, a simple computer quickly calculates the distance to target. This method of distance calculation is capable of measuring the distance from the Earth to the moon within a few centimeters. Laser distance meters may also be referred to as “range finders” or “laser range finders.” Range:0 to 80 m Main features: • Compared with standard laser meter the size of pen type product is significantly reduced. • Laser range finders are equipped with 6th generation optical system. • Cooperating with the latest hardware and software they give the exact distance within a blink. • The hardware structure makes the product anti-shock,dust proof and raindrop proof.
