Usually, the rangefinder telescope has two keys, one is the start measurement key, and the other is the mode key. After installing the battery, press the start key once and the machine will turn on. Aim the eyepiece, and there will be a cross center point in the eyepiece. Aim the cross center point at the target to be measured, press the start key, and the value will be displayed, that is, the distance to be measured. The universal rangefinder telescope can adjust the mode, such as rainy days, foggy days, bows and arrows, and meters. The unit exchange is all with the mode key after measurement. Before measurement, the focal length and eyepiece interval should be adjusted first so that the target can be clearly seen.

Other functions of the rangefinder telescope:

1. Measuring azimuth with a telescope is achieved by dividing its direction. When measuring, the telescope should be level. When the two targets to be measured are within the field of view, align the intersection of the target and the crosshairs or align them in any direction, and then calculate the density between the two targets, which is the direction angle of the two targets

2. Measuring high and low angles

Use a telescope to measure high and low angles, using the high and low division method, the key points of which are similar to measuring direction angles.

Product features:

The accuracy is up to 0.3 meters, combining the functions of ordinary telescopes and laser rangefinders;

The laser emission power is low and safe for human eyes;

No cooperative target is required, and the distance to any target can be measured;

Sensitive distance measurement, small size, light weight, easy to carry;

The machine is powered by CR2-3V batteries, which are easy to buy and replace;

Application areas: electricity, industry, forestry, security, geological exploration, construction, outdoor hunting, camping and mountaineering, etc.
