1. BRIEF DESCRIPTION
LRB 4000CI Laser Rangefinder Binoculars (System) is
an advanced laser range finder system that enables instant
distance, speed, vertical and horizontal angular
measurements. An outstanding optics provides a sharp,
clear image under any observation conditions.
The unit utilises time-of-flight method of distance and
speed measurement. The System sends invisible, eye
safe laser pulses to the target. The returned pulses are
captured by the digital circuitry. The time difference is
used to calculate the distance to the target. A built-in
digital compass measures an angle between the optical
axis and direction to the magnetic North Pole.
The unit complies with CFR 21, Part 1040.10 and Part
1040.11.
A built-in inclinometer allows elevation angle
measurements and height (depth) calculations.
