What's On the Display

The Matrix™ Fishing System can display a variety of useful information about the area
Depth - water depth; can be set to alarm when
the water becomes too shallow.
Cursor - available in Freeze Frame and can be
positioned in the Sonar View to provide depth of a
sonar return and bottom depth below the cursor.
Temperature - water surface temperature.
Timer - Elapsed time with Temp/Speed
Accessory or GPS Receiver.
Distance - Distance traveled with Temp/Speed
Accessory or GPS Receiver.
Average Speed - Average speed reading with
Temp/Speed Accessory or GPS Receiver.
Speed - if a Temp/Speed accessory or GPS
Receiver is attached, the FishFinder can display
the speed of the boat, and can keep a Triplog of
nautical or statute miles traveled.
Second Sonar Return - when the sonar signal
bounces between the bottom and the surface of the
water and back again. Use the appearance of the
second return to determine bottom hardness. Hard
bottoms will show a strong second return, while soft
bottoms will show a very weak one or none at all.
Cursor Dialog Box - indicates cursor depth on the
display and the depth of the bottom directly below
the cursor. The Latitude and Longitude of the cursor
position, the distance to travel to the cursor position
and the bearing to the cursor position is shown with a
GPSreceiver. A waypoint can be marked at the cursor
position for later retrieval and use with a GPS receiver.
NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either
the information from the GPS receiver will be displayed on the view.

Thermoclines - layers of water with different
temperatures that appear at different depths
and different times of the year. A thermocline

colors moving across the display at the same
depth.
83 kHz Blue Fish Symbol
Fish - the FishFinder displays fish as arches
and/or fish icons, and can be set to alarm when
a fish of a certain size is detected. When a
target is detected, a Fish ID+
on the display with the depth displayed above
it. The size of the symbol indicates the intensity
of the sonar return. The unit will clearly show
schools of Bait Fish as "clouds" of different
shapes and sizes, depending on the number of
fish and boat speed.
