INFO ? Particle Disturbance Sensor
This new device uses a variety of detectors and advanced computer systems to identify moving enemy units in water. Click on the Disturbance Sensor icon on the tactical display. Select 'Use Sensor' from the menu. The Sensor display shows an arrow in the centre which is the direction the aquanaut is facing (North is at the top). The blips show units which have moved recently. Large units, or fast moving units, will produce larger blips. Static units will not show up.
