See Echo 3D Imaging Sonar Specification
The See Echo 3D Sonar is based on Marine Electronics digital range of electronically scanning multibeam sonar's utilising an improved wide band technique.
The sonar scans a horizontal sector of 90 degrees to a 1.5 degree resolution and a vertical sector of 20 degrees to a 1 degree resolution simultaneously for every “ping” of the transmitter.
The See Echo provides a true 3D forward looking image updating at a rate dictated by just the travel time for one acoustic pulse, this means a full 3D image is displayed faster than every 2 seconds for up to a 1000m range.
The system consists of separate transmitter and receiver arrays, mounted on the vehicle, cabled to an Electronics Processing Unit.
An optional motion reference unit to stabilise the vehicle movement can be connected to the Electronics Processing Unit.

The sonar data is transferred via a fibre-optic Ethernet link from the Electronics Processing Unit to the host PC where the system is controlled via a touch-screen sunlight viewable TFT monitor.
The system software integrates the data from the sonar and MRU to display a 3D representation of the targets detected in front of the vehicle.
