WESMAR Introduces New Color-Coded Trawl Sleds

WESMAR’s two new trawl systems and five new sled options give trawlers sophisticated electronics with unprecedented information. With the new systems and sled options, trawlers can select the frequency that best fits their fishery and net size.

For trawlers in sensitive fisheries, where quotas are closely monitored, these trawls are exceptionally valuable. Not only are they unequaled in their ability to find and see fish and monitor them entering the net, but with extended discrimination at the net itself it is easier to mark unwanted fish or fish that could upset their quotas. Each system and each sled has advantages to specific applications,” says Dennis Soderberg, WESMAR Vice President.

Both the TCS785 and the TCS385 systems have an operation screen that displays critical towing information. Each system works with up to six catch sensors that include voltage measurement down the cable and third wire communication. The sleds all have memory capabilities, which saves valuable time and ensures greater accuracy by retaining critical settings so they are available every time the system is turned on.

The Model TCS785, is three sonars in one with forward scan, net profile, and sounder. Forward scan is for marking doors and tracking fish; profile for net geometry and fish entry; and vertical sounder to follow bottom and footrope. Depth, temperature, a level monitor, tow timer and level sensor are all displayed on the new screen. The TCS785 has- two sled options. The TCS785-180 (Green)sled at 180 kHz is a long-range system designed for larger nets with a large vertical and horizontal opening. The TCS785-300 (Orange) sled is the higher frequency sled designed for smaller nets. At 300 kHz, the footrope/bottom relation can be viewed in greater detail. The TCS785 series has a working depth of 1800 meters.

The Model TCS385, is a light weight system with a working depth of 1000 meters. This series is designed to profile the net opening. There are three sled options, which greatly expand the ability to identify species and monitor trawl nets. The Model TCS385-180 (Green) has the power to paint the large nets and see the footrope and bottom in high resolution. It is designed for the smaller vessels pulling larger nets and the need to see at greater distance. In profile it operates at 180 kHz; in down sounder at 110 kHz. The Model TCS385-300 (Orange) is ideal for watching the larger trawl nets. It is popular for cod nets and mid-water trawl nets. In Profile it operates at 300 kHz; in down sounder at 200 kHz. The Model TCS 385-500 (Yellow)for differentiating between species of rock fish and for cod and flatfish. Thanks to the extremely detailed discrimination near the bottom, the 500 allows captains to see more dispersed fish and dispersed or low target strength fish coming into the net. This model operates at 500 kHz in profile and 500 kHz in down sounder mode.
