The GX-2S range finder emits invisible, eye safe, infrared energy pulses. Sophisti-
cated digital technology instantaneously calculates distances by measuring the
time, which it takes for each pulse to travel from the rangefinder to the target and
back to rangefinder. The color, surface smoothness, size and sharpness of target
will affect its reflectivity and range.
It is difficult to test in the following conditions and environments:
Raining or fogging/Target is too small/Low reflectivity of the measured object
(dark color, complex shape, curved surface, water surface, glass surface, mirror
surface. etc.)/Low battery.
