Bottom Lock Zoom Mode
B
TM LOCK
(Bottom Lock)
mode tracks the bottom
similarly to Automatic
mode; however, the
display shows a full
range view on right and
a zoomed window on
the left. The zoomed
window provides added
display resolution for
separating sonar returns
that are very close
together, such as those
caused by fish
suspended close to the
bottom.
As the depth changes,
the LEGEND
3000 SERIES
automatically keeps the
bottom visible in the
zoomed window and the
full range view. In the full
range view, horizontal
zoom preview bars
define the area of
bottom being enlarged.
The default setting
varies based on the
depth range; however,
this setting can be
changed to show more
area around the bottom,
or to show the bottom in greater detail.
To change the area of the bottom being zoomed,
follow these steps:
1. Make sure the LEGEND 3000 SERIES is operating in BTM LOCK
(Bottom Lock) mode.
2. Push the RANGE knob. An adjustment indicator
appears by the lower zoom preview bar, indicating
this is the selected depth limit for adjustment.
Note: Pushing the RANGE knob toggles between the upper and
lower zoom preview bar adjustment. If the lower zoom
preview bar is to be adjusted, push the R
ANGE knob until it is
selected.
3.
Rotate the RANGE knob to adjust the zoom preview bar.
Moving the zoom preview bars closer together increases
the display resolution in the zoomed window; moving
them further apart decreases display resolution, but
allows more area around the bottom to be viewed.
The indicators disappear after several seconds with
no adjustment. The L
EGEND 3000 SERIES
continues to follow
the bottom using the new range. Any change made to
the zoom preview bars is remembered until the L
EGEND
3000 SERIES
is powered off, when the unit defaults to
factory settings.
Manual Mode
M
ANUAL
mode turns off
automatic bottom tracking,
leaving control of the
depth range to the user. Both the
upper and lower depth ranges
can be adjusted to show the
bottom, or any other desired
depth, in greater detail. When first
switched to MANUAL mode, the LEGEND
3000 SERIES defaults to the current
automatic depth range; however,
after the manual depth ranges
have been set, the LEGEND 3000 SERIES
uses the new settings until it is
powered off, when it defaults to
factory settings.
MANUAL mode works best in areas
of relatively flat bottom or if you
are trolling slowly. It is also ideal
for displaying a small area of the
overall depth range in great detail
if you are looking for fish at a
specific depth.
To adjust the depth ranges
manually, follow these steps:
1. Make sure the Legend 3000
Series is operating in Manual
mode.
2. Push the Range knob. An
adjustment indicator appears
at the location of the Lower
Depth Range, indicating that it
is ready for adjustment.
Note: Pushing the Range knob toggles
between the upper and lower depth
range selection. If the Upper Depth
Range is to be adjusted, push the
Range knob until it is highlighted.
3. Rotate the RANGE knob to adjust the Depth Range.
Clockwise rotation increases the depth;
counterclockwise rotation decreases the depth. The
display updates as the changes are made.
