Field Evaluation of the ESSLR and CESSLR Devices

摘要

The range estimation capabilities of two eye-safe filters (densities of 2.9 and 5.5) for the M60A3 rangefinder were evaluated under specified conditions of target distance, target reflectivity, and target angle. Both filters were able to range targets out to at least 2000m when targets were enhanced with appropriate reflective materials. While both filters may be useful in tank gunnery training, only the 5.5 density filter can be used in freeplay exercises based on safety conditions.
