3D MODE
The 3D mode shows vertical echoes (real time echoes) and a
frontal or oblique image of the bottom just passed, like a graphic
track plotter. This mode is useful for locating a wreck, a shoal
or a fishing reef. Vertical echoes can be turned on/off through
the BOTTOM/3D menu.
4.1 Selecting a 3D Display
Either of two displays may be selected with the MODE control:
the frontal image at “ ” position, or the oblique image at “ ”.
Example displays of both images are shown below.
Frontal image
The frontal image picture gives a view of the bottom as if you
are looking at it through a rearview mirror. That is, the most
recent data appears at the front if the picture.
