What’s On the Sonar Display
The 700 Series™ can display a variety of useful information about the area under and adjacent to your boat, including the following items:
Timer - elapsed time
with Temp/Speed
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 700 Series™ 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. 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.

Soft Bottom
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.
Fish - fish are displayed as arches and/or fish
icons, and the unit can be set to alarm when a fish
of a certain size is detected. When a target is
detected and Fish ID+
TM 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. Bait Ball
