Down Display
(Conventional down looking)
By pressing the DOWN button - once, the iScan V90’s
display will split and a conventional downlooking display
will appear at the left side of the screen as shown on the
right. The downlooking split screen mode will work in
either the vertical or horizontal display modes.
This down looking display is useful as it shows a history
of the bottom depth directly below the boat.
The vertical scale just to the right of the downlooking
display can be used to determine the depth below the
vessel. The current depth is also shown in the large digits
at the top left of the display. Adjust the
RANGE and
GAIN for the best picture (see page 25).
To see a full screen downlooking display, press the
DOWN button a second time. The display should look
similar to that shown on the left. This display shows the
recent history of the bottom echos. The most current
information is at the right of the screen.
Downlooking Zoom
In the full screen downlooking display, you can
ZOOM
into any 25% portion of the depth being displayed. For
example, if the downlooking depth range is 100 feet, then
the ZOOM function can be used to look at any 25% of
the depth - like 10 to 35 feet, 50 to 75 feet, etc.
To turn
ON the ZOOM feature, press any softkey below
the display to bring up the menu shown at left.
Then press the softkey under the
ZOOM Symbol to bring
up a split screen zoom picture as shown at left.
The normal depth display is on the left side, while the
larger right portion of the display shows the ZOOMED
picture. The
NAV or UP/Down button can be used to
move the ZOOMED area up or down. The ZOOMED
area is the area between the two horizontal lines on the
normal downlooking display on the left.
