The optical device allows you to measure the distance to the object of interest. It is used by surveyors, military, hunters, geologists, builders, as well as travelers. They differ in design and principle of action, depending on the tasks. Military and hunters are required to determine the distance to the target. Builders, it is important to calculate the area. Geologists or travelers need to know the distance they need to go to the intended location. The tool is divided into a combined (monocular with a laser beam) and optical (binoculars).
Top Combined Rangefinders
The device connects in one case the optical system (monocular) and the laser generator. Additionally, an electronic unit was introduced for automatic calculation of the distance or height of the object.
Scanning is carried out by a laser beam operating in a pulsed mode. Lead to the target is carried out by means of a monocular. The measurement process starts by pressing the start button.
