Geophysical Laser Rangefinders
The Geophysical Laser Altimeter is a modified Universal Laser Sensor for use in magnetic environments. The back panel has been replaced with one that has no metal connectors and all fasteners have been replaced with brass. The standard housing is anodized aluminum. One cable with flying leads or a DB9 connector comes out of the back panel. This cable contains power and signal.
