RANGE— The Showdown Troller is equipped with 5-separate depth ranges—
20,40,60,80,and120’.Regardlessofthemanualdepthrangesetting,
Showdown Troller will always display digital depth down to 120’, even if bottom
is deeper than the bottom limit of your current RANGE setting.
AUTO RANGE—In Auto Range mode, Showdown Troller will automatically
lock into the depth range appropriate to the depth of the water. For instance,
in 32-feet of water, Showdown Troller will automatically lock in at the 40-foot
depth range. Auto Range allows you to simply turn on the power and begin
fishing. Your Ice Troller is in Auto Range Mode when you turn it on.

ICE MODE— Your Showdown Troller sonar offers exclusive ICE MODE, a
feature unique to Showdown sonar units, which allows for seamless operation
in the coldest conditions. With ICE MODE active, Showdown Troller triggers
an internal LCD heater that keeps the liquid crystals moving at their normal
super high speeds, regardless of sub-freezing temperature. This means that
anglers no longer have to worry about their sonar “slowing down” due to
freezing liquid crystals. While this feature is called “Ice Mode”, you may find
that your Showdown performs better under a wide variety of conditions when
in “ICE” mode. The extra amount of power used to operate the LCD heater is
insignificant.
NOTE: If your Showdown Troller is left in extreme cold for an extended time
period with the POWER turned OFF, allow one to two minutes for the Ice
Mode LCD heater to warm the crystals sufficiently, after POWER has been
turned ON, and ICE Mode has been activated. After the ICE Mode LCD
heater has been running for an extended period, it is perfectly normal for the
Showdown Troller power-head to feel warm.
TO INITIATE ICE MODE, simply press the UP and DOWN buttons simultane-
ously. You will now see the message “ICE ON” flash briefly at the bottom of
the screen. The internal LCD heater is now activated. To exit ICE mode and
return Showdown Troller to normal operating mode, press the UP and DOWN
keys simultaneously. The message “ICE OFF” will now flash briefly at the
bottom of the screen.
SENSITIVITY— The Showdown Troller is a highly sensitive sonar unit capable
of reading the tiniest of solid objects below. It features a 25-level adjustable
Sensitivity function with surface clutter elimination. Ideally, 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. In most cases, you
will have the best performance with the Sensitivity set between 5 and 10. To
adjust Showdown Troller SENSITIVITY, press the SENS/ZOOM button. The
“SENS” indicator will appear at the lower left of view-screen, along with a
number that indicates the Sensitivity setting (0 to 25) at the bottom of the
screen. With the SENS indicator activated, press the UP or DOWN key to
increase or decrease sonar SENSITIVITY to the desired level.
ZOOM—The Troller has a bottom lock zoom feature that allows the user
to have a close-up look at the bottom 5 or 10 feet of the water column. To
activate the bottom-lock zoom, press and hold the SENS/ZOOM button for
approximately 4 seconds, and the display will change to show the bottom 10
feet of the water column. Press and hold the button again, and the display will
now show the bottom 5 feet of the water column. To exit ZOOM, press and
hold the button again, and you will be back to full water column view.
