What are the characteristics of hand-held laser rangefinders?

Laser range finder is an instrument that uses laser to measure the distance of target accurately. The Laser Rangefinder emits a very fine laser beam to the target while it works. The laser beam reflected by the target is received by the photoelectric element. The time from the launch to the reception of the laser beam is measured by the timer, and the distance from the observer to the target is calculated.

1. The hand-held laser rangefinder generally refers to the laser measuring in the range of 0.05 M to 200 m. Its accuracy is calculated in millimeters, which is simple and convenient to use.

Laser rangefinders over 200 meters are called laser rangefinder telescopes.

3. The indoor hand-held laser rangefinder measures within 60-100 meters. Without built-in magnifying sight, it can only be used indoors (the outdoor sunlight is strong, and the laser spot smaller than the cigarette end can not be seen).

4. The range of outdoor hand-held laser rangefinder is 200 meters (the instrument itself has built-in telescope aiming amplifier, and no reflector is needed for outdoor use in 70 meters of sunshine. If the range of outdoor use is beyond 70 meters in sunshine, please use the reflector in conjunction with it).
