Marport's Tunnel Sounder in Action

These actual recordings were taken by Sonartron onboard the well known Killybegs Vessel Western Endeavour, Skippered by Jens Bach. These recordings were made whilst mackerel fishing of the west coast of Ireland.

One can clearly see the fish entering the brailer and going into the cod-end with crystal clear clarity. The echo from the net and bottom are clearly visible. This new innovative sensor while looking down and back to see fish going into the cod end. Has also depth and temperature, catch , pitch and roll. All in one sensor. The only requirement is a 40Khz transducer and of course Marports revolutionary new underwater technology. No more guessing what's happening at the brailer or are the fish going in, see it yourself. This unit can also be used as a cabless Net sounder. No more cable splices or bad connections. Just a Clear picture of the way ahead (thank you Marport).
