Simrad PI SeineSounder
Applications
Simrad’s PI SeineSounder provides
you with the accurate vertical position
of the gear.
Purse seine
The PI SeineSounder is mounted
vertically below the footrope. From
this position it transmits accurate
information about the height above
the seabed and the depth.
Trawl and Danish seine
The PI SeineSounder is mounted
horisontally behind the headrope.

Sensor key
In order to use the PI SeineSounder
both vertically on a purse seine and
horizontally on a trawl, the echo
sounder inside the sensor is equipped
with two transducers. Before you use
the sensor you must therefore “set
it up” with one of the sensor keys.
These are two special bolts provided
in a gift box.
• LONG bolt for purse seine
• SHORT bolt for trawl
The bolts are screwed firmly in,
but not tightened. Note that ordinary
bolts can not be used!
