Laser rangefinder is inconvenient to measure directly, don't forget to measure Pythagorean
For some situations that cannot be measured directly, the Pythagorean theorem built into the Shendawei SW-M40 handheld laser rangefinder can be used for indirect measurement. Observe the target to construct a right triangle, and then measure the hypotenuse and right-angled sides according to the instructions on the instrument, and then the instrument automatically calculates the length or distance of the measured object.
