Introducing the sensors
The PI54 catch monitoring can be used with a variety of
sensors. All these sensors can be placed on your trawl or purse
seine to monitor key parameters.
On the P I54, you can use maximum six sensors simultanously.
There are two sensor families; PI and PS. The sensors in t he
two families are almost identical, and they can be used together
on the same PI54 system. The PI sensors will however offer
increased range, some added functionality, and they can also be
charged much fas ter using the PI Charger.
Bottom Contact: Best at the bottom!
With patented technology and awardwinning design, Simrad
provides you full control of the actions that take place at the
bottom. Mounted on a bottom trawl, pelagic trawl or purse
seine, this sensor will provide the important information when
you need it!
(A) = The Bottom Contact sensor mounted on a bottom t rawl
will let you know once the trawl lifts a few centimeters above the
bottom. You can then immediatley perform the necessary
adjustments, and you will not loose any catch.
(B) = On a purse seine you will be notified once the seine
reaches the bottom, and you can thus fish even on a rough
bottom.
(C) = On a pelagic trawl, t he sensor will notify you once you get
near the bottom.
The Bottom Contact sensor will let you know immediately if
your gear touches the bottom.
• Bottow trawl: I f 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.
