How deep can you go?
When the sonar
and echo sounder
tell you how deep
the school go, it is
good to know that
you can place your
fi shing gear at the
same depth.
And even better,
you can monitor
and hold the desired
depth.
The design is rugged and awardwinning, and the sensor is
available for three different depth ranges.

The PI Depth sensor provides information
about the current depth and the depth
changes of your gear.
• Bottom trawl: On a bottom trawl, you will use the
sensor to achieve full control when shooting, and
to position the trawl on the slope.
• Pelagic trawl: During pelagic trawling, you know
how important it is to position the trawl relative to
the largest concentration of fish. By using a Depth
sensor, you can monitor the exact depth relative to
the surface, and adjust the trawl depth accordingly.
Additional depth sensors on the doors will monitor
if the doors stay at the same depth.
• Purse seine: During seining, use the Depth sensor
to monitor the depth of the net, and the descending
speed of the net. Then you will know when to start
pursing, and which speed to use.
• Danish seine: Mounted on a Danish Seine the
Depth sensor monitors the sinking speed of the net,
and it will tell you when to start hauling once the
net has stopped sinking.
