BOTTOM EXPLORER BE

The Bottom Explorer minimizes lost fishing opportunities and ensures that the trawl is actively on the ground

Fixed to a trawl’s footrope, the Bottom Explorer provides a constant confirmation that the gear is in contact with the seabed, or an indication that the trawl has risen off the ground, giving the skipper the opportunity to respond by adjusting to wing speed or warp length to place the gear back where it belongs. This minimizes lost fishing opportunities and ensures that the trawl is actively on the ground.

Depth, temperature and pitch & roll data are also part of the package that sends ground contact data with a 3Hz update rate three times per second to the wheelhouse display.

Unlike systems on the market that use a mechanical arrangement to sense ground contact, Marport have opted for an acoustic approach for greater reliability.
