The underwater division was sold to ATLAS ELEKTRONIK UK in 2009 and the Mod 2 version was developed by them.
It is semi-intelligent and reportedly can detect an air-filled chest cavity underwater and let its operator tell whether the echo is from a man or something irrelevant such as a seal or dolphin, and to distinguish between: a shoal of fish; a ship's wake; a diver with an open-circuit scuba set; a stealth diver with a rebreather; flotsam and jetsam.
The portfolio includes a range of optional equipment that enables the user to configure their installation appropriately.
[citation needed] The system has a 360° coverage with an area detection of up to 4.5km2 dependent on the acoustic environment.
The GUI can display 50 tracks simultaneously and, once a threat has been identified, raise an audible and visual alarm to allow the user to take precautionary action.
