Telescope rangefinder - Overview Telescope rangefinder is a branch of laser rangefinder, or long-distance laser rangefinder. Generally, its distance is 500-20000 meters. The main application range is long-distance measurement in the field.

Telescope rangefinder, due to the use of pulse method for distance measurement, generally has low absolute accuracy, but can achieve good relative accuracy for long-distance measurement. Therefore, its measurement blind area is about 15 meters. The measurement error is +/-1 meter.

Features - It is both a telescope and a rangefinder! Multiple observation magnifications, users can easily aim at the target for distance measurement through the cross-aiming system inside the eyepiece! Using transparent infrared laser emission and reception that is harmless to the eyes, it can accurately measure the target distance. It is small, light and easy to carry.

Telescope rangefinders generally use the pulse method to measure distance. The process of pulse method distance measurement is as follows: the laser emitted by the rangefinder is reflected by the measured object and then received by the rangefinder, and the rangefinder records the time of the laser round trip at the same time. Half of the product of the speed of light and the round-trip time is the distance between the rangefinder and the object being measured. The accuracy of the pulse method for measuring distance is generally around +/-1 meter. In addition, the measurement blind spot of this type of rangefinder is generally around 15 meters.

The telescope rangefinder is suitable for power line measurement, construction survey and design, pole spacing measurement, fire protection system, surveying and mapping, military and police, animal investigation, outdoor survey and design, tourism, golf courses, outdoor hunting, camping and mountaineering, outdoor outings and other sports venues. It is a good helper to improve work quality and measure target distance during activities.
