| | | The Bottom Contact sensor will let you know immediately if your gear touches the bottom. • Bottow trawl: If your trawl lifts off the bottom, this may cause fish to escape, and hence reduce the catch. This sensor will detect this, and allow you to trim your equipment for perfect balance. • Pelagic trawl: On a pelagic trawl, this sensor proves very useful when the trawl moves downwards. It will let you know immediately if the footrope touches bottom. • Purse seine: When you work with a purse seine, you need to know when the seine reaches the bottom. This sensor will let you know. once it happens. • Danish seine: Used on a Danish seine, the sensor will let you know when the net has a stable bottom contact, and when it is time to haul. | | |
