The Seine Explorer relays data back to the wheelhouse as a purse seine is shot away and throughout the fishing operation

Mounted on the lead line of a purse seine in a robust protective steel case, the wheelhouse as a purse seine is shot away and throughout the fishing operation. It has been designed to incorporate omnidirectional uplink technology that ensures no loss of signal throughout the fishing operation, starting the moment the purse seine is shot away.

The skipper is shown an echogram of the shot as it takes place, displaying the distance to the seabed and a Scanmar-compatible digital readout of the depth of water above and below the leadline.

For purse seining in shallow water, Marport’s Seine Explorer is an essential tool that ensures the gear can be kept safely clear of ground obstructions so gear damage can be avoided, and in both deep and shallow water the upward-seeking option that provides distance to the surface gives the skipper an accurate indication of the sinking speed of the leadline.
