2D SONAR VIEW
2D Sonar View
is a 2-dimensional view that presents a historical log of 2D sonar
returns. When in 2D Sonar View, your unit operates like a typical depthsounder. The
most recent sonar returns are charted on the right side of the window; as new
information is received, the older information is moved across the display to the left.
There are, however, several exceptions. The 6-beam, 53 degree transducer allows you
to search for fish with a much wider area of coverage. Only the two center beams
provide sonar returns for the bottom contour shown on the display. The fish symbols
shown in the 2D Sonar View are the same as those used in the 3D Sonar View, and
provide information on the location of the fish relative to the boat (see
Sonar Menu
Tab, Fish ID+
). Use the 2D Sonar View for identifying structure and bottom hardness.
NOTE:
If the Depth number is flashing, it means that the unit is having trouble locating the
bottom. This usually happens if the water is too deep, the transducer is out of the water, the
boat is moving too fast, or for any other reason that the unit can’t accurately receive
continuous data.
Freeze Frame -
Pressing any arrow on the 4-WAY Cursor Control key will freeze the
screen in the 2D Sonar View and a cursor and cursor dialog box will be displayed on the
screen. The cursor can be positioned on the display using the 4-WAY Cursor Control key
to determine the depth of any sonar return. The RTS® Window continues to update in
Freeze Frame. In addition, see the effects of menu setting changes with Instant Image
Update.
Pressing EXIT will exit Freeze Frame and the display will start to scroll. Freeze Frame is
only available in the Sonar View.
