LRF MICRO SERIES LRF MOD 25HFLC OEM LASER RANGEFINDER MODULES

The LRF MICRO 1550 and 1550 (CI) utilize a 1550nm laser that cannot be seen by image-
intensified night vision systems. Each ‘CI’ variant incorporates a digital magnetic compass and
inclinometer for vector measurement and enhanced spatial data collection.
