WESMAR fishing sonar solves the tough challenge of seeing fish close to the surface and close to the bottom.
The SMART sleds are available in two profiler frequencies, 180 kHz and 300 kHz. The lower the frequency, the longer the range.
The TCS785-300 kHz orange sled has a higher frequency profiler with high-resolution designed for smaller nets. At 300 kHz, the footrope/bottom relation can be viewed in greater detail.
The TCS785-180 kHz green sled with a 180 kHz profiler is designed for larger nets with large vertical and horizontal openings.
The captain receives a wealth of information from WESMAR's trawl sonars. This information enables them to increase catching efficiency through shorter tows and reduced fuel consumption. Gear damage is also reduced by avoiding rough bottom and overfilling of the net.
The TCS785 trawl sonar is a "third wire" system that combines forward looking and profiling in one headrope unit. Its split screen feature allows measurement of the net opening, profile of fishing circle, door spread, and other gear geometry. The pressure sensor continuously monitors depth of headrope making it possible to align the net and fish as they pass under the vessel.
Built rugged, yet lightweight, the TCS785 sled, when submerged, adds only 10 kg (21 lbs.) to the headrope.

TCS385-500 is ideal for differentiating between species of rock fish and for finding cod and flat fish. Thanks to the extremely detailed discrimination near the bottom, the 500 allows captains to see more dispersed fish and low target strength fish coming into the net. Captains say they can even differentiate between fish species. (Profiler and Downsounder both operate at 500 kHz.)
The TCS385-300 trawl sled is ideal for watching larger trawl nets to ensure fish are not escaping. Popular for groundfish and mid-water trawl nets. (Net Profiler/Split Screen operates at 300 kHz; Downsounder 200 kHz.)
The TCS385-180 trawl sled has the power to paint the large nets and see the footrope and bottom in high-resolution. Designed for vessels pulling larger nets and the need to see at greater distance. The 180 kHz trawl is ideal when longer range is important. (Profiler/Split Screen operates at 180 kHz; Downsounder 110 kHz.)
The choice of profiler frequency gives you the ability to pick the one that will work best for your fishing application.
