1. BRIEF DESCRIPTION
LRB 3000PRO Laser Rangefinder Binocular is an advanced
Laser Range Finder system that provides instant distance, speed,
and angular measurements consistently and accurately. The
outstanding optics provides a sharp, clear image under all
conditions. LRB 3000Pro utilizes a revolutionary digital design,
which outperforms any other product in its class and price range.
The unit sends an invisible, eye safe laser beam pulses to the
target. The returned beams are captured by the digital circuitry.
The time differential allows us to calculate the distance to the
target. Incorporated digital compass measures clockwise the
angle between the optical axis and direction to the North Pole.
