LRB 4000CI

NSN#: 1240-20-001-9644

The LRB 4000CI medium range laser rangefinder binoculars combine uncompromised 7×50 optics with advanced data processing algorithms. The rangefinder instantly measures distance up to 4,000 meters (output display in yards also), accurate azimuth and inclination via an in-built digital magnetic compass, and speed using the highly accurate time-of-flight delay method. LRB 4000CI also features RS-232 interface that enables immediate data acquisition by computers, external GPS receivers and various ballistic computers.

A gating algorithm implemented in LRB 4000CI dramatically improves reliability of measurement in unfavourable measurement conditions (e.g. rain, snow, bushes, wires, etc). Low power-consumption (one battery lasts for more than 5000 shots), ergonomic rubber-armoured body, long eye-relief, simple two-button operation, and wide objective lenses make observation and distance measurement with these binoculars accurate and comfortable.
