What's On the 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, 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.
