Sector scan type sonar system, covering a 45-degree sector/ping through 360 degrees for high speed fishing or navigational application. Conventional searchlight scan mode is also selectable in 2 sector width steps for operation requiring slow or high-density sonar imagery across a limited bearing range.

Automatic selection of optimum transit power level and pulse width for the range in use; pulse length may be fixed on all ranges.

Operating modes include sonar (normal/off-center), sidescan (bottom scan) and echo louder, each mode image spread across full screen area or split screen displays with the sub display listing major system parameters or vertical, time-wise compressed presentation of sonar or sidescan echogram.

Single-touch keypress for instant storage and recall of 3 sets of user-defined system parameters optimised for different type of fishing, different underwater conditions or for use by different sonar operations.

Target lock function allows the energy beam to stay locked onto a user-specified moving target while manoeuvring the ship.

Built-in transducer stabiliser allows energy beam tilt to stay fixed at user- specified angle regardless of ship's pitching/rolling.
