What’s On the Sonar Display
The FishFinder can display a variety of useful information about the area under and adjacent to
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 Matrix™ 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 bottomswillshowastrongsecondreturn,whilesoft 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. In addition, the Latitude and Longitude of the cursor position is shown, the distance to travel to the cursor position and the bearing to the cursor position. A waypoint can be marked at the cursor position for later retrieval and use.
your boat, including the following items:
High Sonar Intensity Return
Bait Ball
Thermoclines - layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of many colors moving across the display at the same depth.
Fish - are displayed 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+TM symbol appears 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.
200 kHz Fish Symbol
Structure - where fish may be hiding.

Low Sonar Intensity Return
NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either device is | connected to the Fishing System. If both devices are connected, then only the information from the |
