Humminbird 405SX Fish Finder User Manual


 
Temperature/Speed. The initial screen layout takes one of two basic forms
depending on whether the optional Temp/Speed accessory is installed. Figure
A shows the default view when the Temp/Speed accessory is installed. Figure B
shows the default view when the Temp/Speed accessory is not installed.
Depth. The digital depth
number shows the water depth
directly beneath the transducer
location.
Depth Range. The depth range
is shown to the right of the screen.
The upper number is 0 indicating
the surface of the water. The lower
number is one of the nine depth
ranges available that best match the
depth of the water. As the depth of
the water changes, the range
changes as necessary in order to
retain a bottom representation on-
screen. When in Auto mode,
the horizontal line at the top
of the screen is the zero
line, representing the surface
of the water. Occasionally
there is a gap in this line. This
gap indicates the unit is up-
dating the display even if the
bottom is not visible on-
screen, or if the bottom
information is not changing.
New sonar information appears
on the right side of the graphic
area of the display and moves
to the left as new information
is displayed. The
405SX
automatically selects the
appropriate depth range to show the depth of water beneath the transducer.
