LRB 20000C

The LRB 20,000C is designed for ground surveillance, target observation and distance measurement out to 20,000m. This rangefinder employs a proven time-of-flight delay algorithm to ensure accuracy and a single strong impulse to minimize exposure time.

With an optional angular mount both can also measure horizontal angles and magnetic azimuth as well as vertical angles. The result of distance measurements is displayed through the eyepiece and can be transferred for processing via computer output. The unit can also be remotely triggered via RS-232.

This robust rangefinder can be used in defense, geological and engineering surveying, construction and repair works, maritime navigation, meteorology and other activities that require accurate long range distance measuring.
