mode, it is easy to experiment with the various settings to see how they work
and what effect they have on your display. While in SIMULATOR mode, you
will not hear the “ticking” sound coming from the transducer.
ICE MODE— Your Showdown Troller sonar offers exclusive ICE MODE, a
feature unique to Versa Electronics brand sonar units, which allows for seam-
less 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 Show-
down 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

When you get home from a trip, put your battery on charge right away, and
leave it there overnight, or for around 8-12 hours. Likewise, on the night
before you go ice fishing, put it on the charger again, just to make sure. Again,
there is no danger of overcharging your battery. We often talk to people who
hesitate to charge their battery after each use for fear that the battery will de-
velop a “memory” and this will lead to a shortened run time—THIS IS FALSE!!!
ALWAYS CHARGE YOUR BATTERY AFTER EVERY USE!!! Be sure to use the
charger that came with your system, or a similar one that is between .5 amp
and 1 amp. Using a larger charger, like you would use on a car, truck, RV, or
boat is likely to cause damage to the battery. There is really very little danger
of overcharging your battery with a low amp charger, and most chargers auto-
matically go into “maintenance mode” once a full charge has been achieved.
To charge, simply couple the end of the charger with the end of the wiring
harness. It is normal for a green light to appear on the charger at this time. It
is also normal for the light on the charger to be green if it is just plugged into
the wall. When it is plugged into the wall and battery, you will see a red LED
light appear on the charger. If the light is red, the battery is being charged.
When your battery is fully charged, this red light should change to green. If it
is time to go fishing and the light has not turned green, go fish and try to allow
a longer charging period next time.
Showdown Troller Features
The Showdown’s straightforward control panel is designed to let you con-
centrate on fishing. Most settings work by first activating the function itself
(ex: press SENS to trigger sensitivity adjustment), then simply press the UP or
DOWN keys to adjust levels.
POWER ON— To turn the Showdown Troller POWER to ON, press and hold
POWER key for two seconds. The unit will beep, and a message will appear
briefly at the bottom of the screen—this message indicates which software
edition that your system is equipped with, and whether ICE MODE is on or
off. (See below to activate ICE MODE). It is normal to hear a “ticking” sound
coming from the transducer whenever the Troller is operating.
POWER OFF— To turn the Showdown Troller POWER to OFF, press and hold
POWER for two seconds. Showdown Troller automatically preserves your
sonar settings the next time you activate unit.
BACKLIGHT— To turn backlight on, turn Showdown Troller POWER ON,
then press POWER key again (do not hold key down). To turn backlight off,
press POWER momentarily again (do not hold button down).
SIMULATOR mode— With Showdown Troller POWER OFF, enter
SIMULATOR mode by pressing and holding POWER key for 5 seconds. “SI”
will appear on the bottom of the screen, indicating you are in SIMULATOR
mode. SIMULATOR mode shows how the bottom, a lure and fish would
appear on the screen if you were fishing in 32’ of water. To exit SIMULATOR
mode, turn the Showdown Troller POWER to OFF, then turn unit back ON.
While in SIMULATOR mode, it is easy to experiment with the various settings
to see how they work and what effect they have on your display. While in
SIMULATOR mode, you will not hear the “ticking” sound coming from the
transducer.
