1. Long-distance measurement, mostly used for outdoor use.
Suggestion: buy "laser ranging telescope".
Features: It is both a telescope and a
rangefinder. With multiple observation magnifications, the user can easily aim at the target for distance measurement only through the cross sight system inside the eyepiece! Using the transparent infrared laser emission and reception that is harmless to the eyes, the target distance can be accurately measured. It is small in size, light and easy to carry! There are also some products with many functions, which can measure the height and the distance between any two points.
2. You only need to measure the distance within a few meters or more than a dozen meters, and you choose an ultrasonic rangefinder when the accuracy is not high. This kind of instrument is basically eliminated by the market.
3. The measurement distance is 20-250 meters, and it is mostly used indoors, with high precision requirements.
Suggestion: buy "Handheld Laser Rangefinder".
Features: It is especially suitable for the measurement of buildings with complex structures, middle and high-rise buildings, and long-distance buildings. Easy to use, accurate measurement data, improved work efficiency (non-contact measurement), completely abandon the method of measuring houses with a tape (or steel tape), reduce surveying errors, and ensure the accuracy of area measurement.
