TO INITIATE ICE MODE, simply press the UP and DOWN buttons simultaneously. You will now see the “ICE” mode indicator appear at the top of
the Showdown 5.6 Dual Beam display screen. In ICE mode, an internal LCD
heater is initiated. To exit ICE MODE and return Showdown 5.6 to normal
operating mode, press the UP and DOWN keys simultaneously. The ICE
MODE indicator will no longer show at the top of the display screen.
SENS (SENSITIVITY) — The Showdown 5.6 is a highly-sensitive sonar unit
capable of reading the tiniest of solid objects below. It features a 25-level
Sensitivity function that adjusts either automatically or manually. By simply
turning on your Showdown, it will automatically select a level of sensitivity
appropriate for the given depth and signal strength. Ideally, the Sensitivity
should be set at the lowest level possible to still view your lure and surrounding fish, while at the same time “tuning out” excessive clutter in the water
column. Clutter can make reading the sonar screen more difficult. Clutter can
be caused by any number of suspended items, including algae, zooplankton,
tiny bubbles, and other particles.
If you’re seeing too much clutter, simply decrease the Sensitivity level until the
clutter disappears. Conversely, if you’re not reading your lure directly below
the transducer, consider increasing the Sensitivity level.
MANUAL SENSITIVITY— While your Showdown will automatically select an
appropriate level of sensitivity, you may wish to adjust the level yourself. To
manually adjust Showdown 5.6 SENSITIVITY press the SENS button. The
“SENS” indicator will appear at the lower left of view-screen, along with a
number and bar indicator that displays Sensitivity level (0 to 25) at the bottom
of the screen.
With the SENS indicator active, press the UP or DOWN key to increase or
decrease your SENSITIVITY to the desired level. In most cases, you will
have the best performance with the Sensitivity set between 5 and 10.
RANGE— The Showdown 5.6 is equipped with 6 separate depth ranges—20,
40, 60, 80, 120, and 240-feet. Regardless of the manual depth range setting,
Showdown 5.6 will always display digital depth, even if the bottom is deeper
than the bottom limit of the RANGE setting, (down to 240’).
AUTO RANGE— In Auto Range mode, Showdown 5.6 will automatically lock
into the depth range appropriate to the depth of the water. For instance, in
32-feet of water, Showdown 5.6 will automatically lock in at the 40-foot depth
range. Auto Range allows you to simply turn on the power and begin fishing.
MANUAL RANGE— To manually adjust the Showdown’s depth range, press
the RANGE key. This will cause the digital depth markers to flash on-and-off,
indicating that the sonar has switched from AUTO RANGE mode to MANUAL
RANGE mode.
While the display is flashing, press either the UP or DOWN key to toggle
between depth ranges—20-FT, 40-FT, 60-FT, 80-FT, 120-FT, 240-FT. Pressing
UP moves RANGE to the next shallower depth zone; DOWN moves to the
next deeper zone.
