The accuracy of onick L Series upgraded laser rangefinder mainly depends on the calculation accuracy of the instrument to calculate the time of laser transmission and reception. According to the technology and application used, the laser rangefinder can be divided into conventional laser rangefinder (mainly used for outdoor sports, hunting, etc.), with an accuracy of about 1 meter, mapping, land surveying, construction, engineering applications, military and other high-precision laser rangefinder.
The phase method rangefinder is a rangefinder that modulates the laser phase and obtains the distance by measuring the phase difference of the reflected laser. Since the reflected laser phase needs to be detected, the received signal needs to have a strong intensity. Considering the safety of human eyes, telescopic systems such as pulsed laser rangefinder cannot be used, and the range is small. Because the propagation speed of ultrasonic wave in the air is greatly affected by temperature, humidity and air pressure, the measurement error is large.
Because the ultrasonic wave wavelength is long and the propagation distance is short, the general ultrasonic rangefinder measurement distance is short and the measurement accuracy is low. However, the characteristics of ultrasonic as a fan transmission is greater than that of photoelectric distance meters, and it is widely used in security protection, cable height measurement, obstacle detection and other fields.

Product features:

1. The accuracy is up to 0.3 meters, combining the functions of ordinary telescopes and laser rangefinders

2. The laser emission power is low and safe for human eyes

3. No cooperative target is required, and the distance to any target can be measured

4. The distance measurement is sensitive, small in size, light in weight, and easy to carry

5. The machine is powered by CR2-3V batteries, which are easy to buy and replace

Application areas: 

Golf, Electricity, water conservancy, communications, environment, construction, geology, police, fire, blasting, navigation, aviation, railways, counter-terrorism/military, agriculture, forestry, real estate, leisure/outdoor sports and other fields.
