TO INITIATE ICE MODE, simply press the UP and DOWN buttons simul-
taneously. 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 Dual Beam 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 objects below. It features a 25-level Sensitiv-
ity 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 Dual Beam 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 Dual Beam will always display digital depth,
even if the bottom is deeper than the bottom limit of the
RANGE setting
(down to 240’).
AUTO RANGE— Your Showdown 5.6 Dual Beam will automatically lock into
the depth range appropriate to the depth of the water. For instance, in 32-feet
of water, Showdown 5.6 Dual Beam 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.
