What’s On the Display
The 300 Series™ Fishing System can display a variety of useful information about the area under and adjacent to your boat, including the following items:
Depth - water depth; can be set to alarm when the water becomes too shallow.
Speed - if a Temp/Speed accessory or GPS Receiver is attached, the 300 Series™ can display the speed of the boat, and can keep a Triplog of nautical or statute miles traveled.
Cursor - available in Freeze Frame and can depth of a sonar return and bottom depth
be positioned in the Sonar View to provide below the cursor.
83 kHz, Wide Beam Hollow Fish Symbol
Structure - where fish may be hiding.
Fish - fish are displayed as arches and/or fish icons, and the unit can be set to alarm
Temperature - water Do Not print this page
Timer - elapsed time

when a fish of a certain size is detected. When a target is detected and Fish ID+ is on, a Fish ID+TM symbol with depth is displayed. The size of the symbol shows 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, Narrow Beam Shaded Fish Symbol

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 directly below the cursor.
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 gray levels moving across the display at the same depth.
Soft Bottom
RTS® (Real Time Sonar) Window
Battery Voltage - the voltage of the boat’s
on the display and the depth of the bottom battery; can be set to alarm if the voltage falls below a certain point.
