Rip sensor
IP
- provides information about trawl entrance height and stability.
- provides info about whether the ground gear is on or off the bottom. Increase your efficiency; stay in touch with the bottom.
- provides information about the filling rate of fish in the cod end.
- monitors if the trawl belly is damaged. Detect a ripped trawl
early to minimise the damage.
- provides information about the depth and descending/ascen­ding rate related to the surface.
- enables you to monitor and boat log the tempera­ture. Fish and bait are temperature sensitive and are located in zones.

The trawl belly is not damaged.
Catch sensor is triggered and has been triggered for 38 minutes during the last tow.
The temperature is 6.8o C .
Numeric display showing 5.8 m trawl height and increasing with 1m per minute.
Bottom contact is indicated on screen and with an audio alarm. The net has been off the bottom for 9 minutes.
Numeric display showing depth in meters and the descent rate in meters per minute.
• Catch volume according to your production capacity.
• See if the cod end
is intact and the trawl
is fishing.
• Secure the catch quality.
• Minimise towing time and save fuel.
• Full control with trawl opening in
shooting phase.
• Enables you to have a smooth touch down.
• Detects incorrect rigged and unstable trawls.
• Monitor if the trawl belly is damaged.
• Detect a ripped trawl early to minimise the gear damage and cost.
Monitor and log the temperature to see if you are fishing in the right temperature
zone.
• Know where the trawl is on the slope.
• Full control during shooting of the trawl.
• Gives an alarm if the ground gear lifts off the bottom.
• Trim the foot rope weight till you have the perfect balance.
• Reduce fish leakage.
• Avoid trawling on the bottom; the bottom contact sensor gives alarm when the sensing weight touches bottom.
• Mount the sensor on the foot rope to avoid gear damage.
• Mount it in the intermediate section to detect if the trawl collapses.
• The Temperature sensor enables you to monitor and log the temperature.
• Fish and bait are temperature sensitive and are located in temperature layers.
• Position the trawl at the right depth according to the fish concentration.
• Full overview with additional Depth sensors on the foot rope or the cod end.
• Catch volume according to your production capacity.
• Avoid splitting the cod end.
• See if your trawl is fishing.
• Monitor if the trawl belly is damaged.
• Detect a ripped trawl early to minimise the gear damage and cost.
• The bottom contact sensor gives an alarm if the ground gear lifts off the bottom.
• Trim the foot rope weight till you have the perfect balance.
• Mount two or more sensors to see if the
wings are lifting.
• Full control with trawl opening in shooting phase.
• Enables a smooth touch down.
• Detects incorrect rigged and unstable trawl.
• Catch volume according to your production capacity.
• See if the cod end
is intact and the trawl is fishing.
• Secure the catch quality.
• Minimise towing time and save fuel.
• Know where the trawl is on the slope.
• Full control with additional Depth sensors on the foot rope or the cod end.
• Monitor and log the temperature to see if you are fishing in the right temperature
zone.
• Monitor if the trawl belly is damaged.
• Detect a ripped trawl early to minimise the gear damage and cost.
• Monitor the descen­ding speed of the net.
• Start pursing at the right time.
• Purse with right speed.
• Mount two or more sensors.
• Monitor the tempe­rature in the water column.
• Detect where the thermo cline is.
• Catch fish close to the bottom.
• The Bottom contact
sensor gives an
alarm when the sensing weight touches the bottom.
Award for exellent design
The PI sensors are sealed entirely in polyurethane for protection, making them virtually unbreakable. They look great too - with the PI range recently
winning a top Norwegian design
award!
• Monitor and log the temperature to see if you are fishing in the right temperature
zone.
• Monitor the sinking speed of the net.
• Start hauling when the net reaches bottom.
• Avoid lifting the net off the bottom.
• Make sure the net is in balance.
• Mounted on the head rope to have full control of distance from head rope to bottom during setting and hauling.
• Detects if the net is balanced and stable for optimum catch.
