When selecting a range finder, first of all, we must know that laser range finder is divided into two categories. One is a handheld laser range finder. This type of range finder has a relatively short measuring distance, generally 40-250 meters, and has high measurement accuracy. The other type is the laser range finder telescope. This kind of laser range finder measures a long distance, generally 500-2000 meters, and the longest measuring distance can reach 20 kilometers.
In addition, the laser telescope range finder can also be divided into a single-tube laser range finder and a dual-tube laser range finder, and the single-tube laser range finder is relatively low in price. The dual-tube laser rangefinder is expensive but easy to use.
