Trawl sonar TS-331A

Vertical scanning sonar 180/360 ° (or other sectors). dual frequency vertical sonar, 330kHz, 10-250 m scale. Sounder: 120 kHz, 50-300 m scale. Digital signal processing, Windows based. Operated with mouse/trackball. Full Windows layout with many own user settings. Temperature sensor. Depth sensor. Roll & Pitch sensor. Up to 4 Catch Sensor Interface. Approved for depths down to 2000 m. Voltage: 220V AC.

Catch sensor CS-400

Catch sensor for trawl sonar with approx. 1.000 operation hours in sea, with 3pcs of normal LR20 batteries. Stable signal output witch stars when sensor has seawater connections. The clock starts counting 2 minutes after activation of the tension spring. Simple indicator show how many hours the sensor has been active. User-friendly battery that can easily be done on board. Operating frequency is 70 kHz.

Catch sensors

Catch sensor, can be supplied with: single, double or simultaneous frequency of 40 kHz and 70 kHz. The sensor combines high sensitivity, fast reaction time and refresh rate. Field programmable and can be implemented directly to existing competitive systems. 

Catch Explorer

Catch Explorer is a downward-looking sensor fitted on the top sheet of a cod end or in the tunnel to monitor the contents of the cod end. The Catch Explorer gives a rolling echogram image of the catch volume in addition being a normal catch sensors that are triggered as a certain fish amount has been caught.

Bottom Explorer

Bottom Explorer is a downward-looking sensor fitted on the foot rope and gives constant information where the gear is according to the see bead. The Bottom Explorer gives a rolling echogram image with every second as update rate. 

Depth sensor

Depth sensor monitors the descent / ascent speed plus change in depth rate. All depth indications are relative to the surface. Temperature sensor measures the sea temperature. Field programmable. Can directly be implemented to existing competing systems.

Rip sensor

Rip sensor is mounted below or in the tunnel area on the trawl. It detects any tear in the net and avoid fish escape. Field programmable and can be implemented directly to existing competing systems.

Seine Explorer

Mounted on the lead line of a purse seine. Designed to incorporate omnidirectional uplink technology that ensures no signal loss throughout the fishing operation. Rolling echogram that updates every second and shows the distance to the sea floor. At the same time are numerical and graphical information shown of temperature, Depth and Height. Window for battery status.

MFX Door Sensor

MFX door sensor "SMALL FRAME", measures the distance between the trawl doors. Transverse acoustic link 110 or 144 kHz. MFX door sensor is suitable for small semi-pelagic and smaller close on the bottom trawldoors where size and hydrodynamics prevents mounting of larger sensors.

Clump sensor

Clump trawl door sensor measures the distance to trawl doors. Correct operation of the sensor indicates  whether the Clump is ahead or behind the trawl doors. With proper rigging one will obtain maximum spread and trawl opening.

Trawl speed and grid sensor

Trawl speed and grid sensor visualizes waterflow in two axes; along and across current of the trawl. Comes with Pitch & Roll as standard. Can also be used for evaluating the water flow and speed through the tunnel. Furthermore, the sensor can be used on the grid to confirm grating angle, proper operation and water flow through the grid.

Trawl eye explorer

Trawl eye with dual frequency Down/Down Mode allowing differentiation between fish species. Designed for mounting on the head rope or tunnel installation. Delivery with depth, temperature and Pitch & Roll as standard. Available with high resolution digital narrow band with fast up-date rate.
