To change the frequency:
1. Press the
FREQUENCY
soft key. The frequency selection soft keys are dis-
played.
2. Press the appropriate soft key –
50 KHZ, 200 KHZ
or
SPLIT.
The scrolling bot-
tom is displayed in the selected frequency. If you choose split, the scrolling
bottom is displayed in both frequencies with 200 kHz in the upper window
and 50 kHz in the lower window.
3. If necessary, press the
AUTO FREQ OFF ON
soft key to select
AUTO
fre-
quency.
AUTO
frequency is indicated by the letter
F
in the status bar.
4. Press
ENTER
or
CLEAR
to return to the default display.
You can choose the split frequency display with the fishfinder display options,
Bottom Lock, A-Scope, or Zoom.
When the
RANGE
has been manually set to 400 ft (150 m) or greater, the digital
depth calculation will be made at 50kHz, regardless of the
FREQUENCY
setting
used. 200kHz can still be displayed, but will not be used in determining the
depth.
Using Bottom Lock
The scrolling bottom display provides a
top-down
view, referenced from the
surface of the water. Bottom Lock shows a water column of fixed height,
referenced from the bottom, that appears flat. It removes bottom detail to
provide an image of objects directly above the bottom, and is useful when you
are looking for fish that feed close to the bottom.
You can select the Bottom Lock image to be vertically split with the scrolling
bottom display, or it can replace the scrolling bottom display.
As illustrated in
Figure 3-9
, the bottom is shown as a straight line. Notice that
some bottom features may extend above this line. The actual depth reading is
given in the bottom left hand corner of the Bottom Lock display.
Range intervals on Bottom Lock are measured up from the bottom (rather than
down from the surface). Thus, the bottom is shown as zero and the top number
indicates the maximum distance above the bottom being displayed. You can
adjust the Bottom Lock range.
If the A-Scope or Zoom image was displayed, selecting Bottom Lock
automatically switches
OFF
A-Scope or Zoom.
If you have split frequency selected, the Bottom Lock image is displayed in
both frequency windows.
If Target Depth ID is
ON
(see
Target Depth ID
on
page 7-13
), the target depth
is displayed as distance from the bottom.
