Evaluate the school while still tracking up to 3 other targets...

Purse seine data

The seine indicator shows the time from the net was shot, the length of shot net, and the total net length. Also the net sinking is shown graphically. With a Simrad PI32 connected the correct net depth and sink rate will be shown in relation to the school and the bottom.

Catch data

All the vital school data is available: Depth, distance, bearing, speed, course, area and volume in tons. In addition, the geographical position in latitude and longitude canbe displayed when a BOAT GPS is connected.

Vertical view

The vertical view is used for showing the vertical distribution of the school. The tilt angle indicator helps in optimizing the tilt angle for the best picture in the horizontal view. In auto-matic target tracking, the verticalview remains locked on to the selected target. Aschool of fish is detected and tracked by the sonar. The school’s swimming speed, swimming direction and swimming history are shown on the screen. This helps the skipper to find theright time and position for setting the net.The yellow purse seine symbol is set around theschool. The seine dimensions are entered into the sonar for up to three different purse seines. When using the PI32 and depth sensors, each mark will have depth and sink rate values indicated on the screen next to the markers.

Purse seining The flexibility of the screen presentation gives an optimal overviewof the catch situation, where all vital data about the school of fish and the gear are displayed. This is a result of a close collaboration with professional sonar operators, who understand the need of reliable information combined on a single screen.

For securing the catch by pursing at the right moment, the Simrad PI32 Net System with three PS30 depth indicators are attached to the bottom of the net.The PS30 sensor is designed to withstand the extreme forces the sensor encounter when shooting and hauling a purse seine. The Simrad sonar gives a purse seiner a total overview of the catching situation by allowing the skipper to see the fish school in two planes at the same time. After the seine is set he is in full control of the pursing by using the PI32 depth indicators.
