Solid bottom contact sensors
Accurate purse seining
Data sharing
Depth and temperature
Surface temperature meter
Purse seining with two depth sensors
and one temperature sensor. The
water temperature is indicated in
the blue area. The ground line is
passing through a thermo cline.
Display with an alarm function, set
for increasing or decreasing tempe-
rature. Temperature versus time can
be shown graphically on the lower
part of the display.
Integrated information from the PI
system can be sent to other Simrad
equipment. Here is information from
3 depth sensors displayed in relation
to the fish school on a Simrad SP90
sonar.
All metal parts on a PI
sensor is made out of
titanium to ensure
durability and a long
lasting sensor.
The Bottom contact sensor monitors if the ground gear is on
or off the bottom. Increase your efficiency; stay in touch with
the bottom. Do not tow with heavy bottom gear; trim it till you
have the perfect balance.
The Simrad PI Catch Monitoring
system receives information from
up to six sensors at the same
time. The system uses a hull
mounted- or over the side hydro-
phone. The net’s depth, water
temperature and the important
bottom contact information are
displayed in large digits or easy
to understand graphics. The
Simrad PI system is designed
with different codes to avoid
interference between vessels
operating close together. The
small size, quick update rate,
long battery life and its long-range
capability, allows the PI system to
be installed on any size net, from
a small sardine net to a large
tuna net. The PI system inter-
faces to the latest professional
Simrad echosounders and
sonars.
Bottom contact sensor on
a bottom trawl gives you fast
update and accurate information.
Adjust the length of the sensing
chain to see when the ground gear
lifts a few cm off the bottom.
Bottom contact sensor on a purse
seine gives an alarm when the
sensing weight touches the bottom.
This enables you to fish close to a
rough bottom.
Bottom contact sensor on a
pelagic trawl. Adjust the length of
the sensing chain to avoid towing
on the bottom and tearing the net.

Bottom contact is indicated on
screen and with an audio alarm.
The net has been off the bottom
for 7 minutes.
