What's On the Sonar Display

The 700 Series™ Fishing System can display a variety of useful information about
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 Fishing System 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 GPS receiver. 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
information from the GPS receiver will be displayed on the view.
