About Your New Showdown Troller Handheld Fish Finder
Congratulations! Your new Showdown Troller Digital Fish Finder is a palm-
sized sonar device with full size performance. For use in either ice-fishing or
open water situations…quickly “troll” from hole to hole while ice-fishing or
shoot through your canoe or kayak order to find fish and the correct depth.
The ultimate in portability is matched to ShowDown’s proven Crystal-Quick®

equipped with a 12V “pig-tail” lead that can be attached to an optional acces-
sory, the Showdown Troller Performance Pack. The Troller unit can be placed
in and removed from the performance pack with ease by using the Quick-
Slide bracket that comes with the performance pack. Feel free to keep AA
batteries in place while using the performance pack—when you are connected
to the big battery, you will be using current from the big battery. Should you
choose to go on a “scouting mission”, you can quickly and easily disconnect
the pigtail connection to return to running on AA battery power.

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

SIMULATOR— 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 Show-
down 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.
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

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

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.

Other Showdown Troller Features
Backlight— Your Showdown Troller offers a warm “nightglow” backlight that
actually accentuates the pixels in the display. The backlight can be turned on
or off by briefly pressing the POWER button after unit is ON.
Digital Depth— The digital depth display on the Showdown Troller sonar
provides a quick and easy way to determine depth. Digital Depth is always
displayed in the bottom of the display. In addition, the digital depth scale
indices are shown to the left of the display area for quickly determining the
depth of fish or your lure.
Low Battery Warning— When battery power reaches very low levels, a
low battery indicator will appear and flash at the top right of the display. An
audible beep will also sound every 30 seconds. This signifies that it is time to
replacethe6AAbatteries,orrechargethe12voltbattery.
“Last Settings” Memory— Your Showdown Troller automatically remembers
the settings you used last. So when it is turned OFF and then ON again, your
previous settings will be preserved and active.
Tips For Using Your Showdown Troller
Setting up the transducer: When placing the Showdown Troller Transducer
in an ice- hole or over the side of a watercraft, the transducer will automati-
cally level itself—accurately displaying the water depth and other underwater
features like fish and weeds. When using the transducer to “shoot through”
the bottom of a canoe, kayak or other watercraft, be sure that the bottom
of the transducer is level before attempting to shoot through, so a positive
bottom reading can be seen. Many anglers successfully shoot through the
hull of their canoe or kayak by placing a wet towel on the floor of their boat,
then placing the transducer on top of that. When Ice-Fishing, we recommend
having transducer down the least amount possible. The Showdown Ice Troller
puts out enough power that in most cases it is not necessary to have your
transducer down more than a few inches below the water line to get a good
reading. When the ice thickness is over two feet, it may be necessary to have
your transducer set farther down. Remember--the less transducer cable you
have out, the easier it is to pull it out of the water when bringing in a fish, or to
move to a new location.
How to Read the Showdown Troller sonar signals: The Showdown Troller
displaysthewatercolumninitsnaturalstate(vertically),ratherthaninacircu-
lar configuration. On the Showdown, top is the surface, and bottom is bottom.
Bottom appears as a dark solid bar above decreasingly solid bars below. A
thicker “bottom band” indicates a harder bottom composition, such as rock,
gravel or sand. A thinner band indicates a softer bottom.
Generally, a solid band that appears on the screen between the surface and
bottomindicatessomeformofaquaticlife(gamesh,baitsh,insects,plank-
ton,etc.),oryourlure.Thicker,ormoresolidbands,implylargerobjects,such

transducerthansmallerobjects.

At the same time, even a large fish may not return a strong signal until it
swims directly beneath your transducer. This is because the transducer emits
a cone-shaped signal that increases in diameter as the signal travels deeper.
Therefore, not only will a fish appear to grow in size as it travels beneath the
transducer(thesignalhasbecomestronger),butitwillalsoappeartobe
swimming from deeper water to shallower water, even though this may not be
the case at all. A fish that’s swimming at 25 feet may not display at 25-feet
until it passes directly beneath the sonar transducer. That’s simply because
the sonar signal travels further to return an echo from a fish that’s off to the
side than it does for a fish that’s directly below.
How do I “see” my lure?
The best way to find your lure on the Showdown Troller screen is to simply
drop it down to bottom, then reel it up about a foot. You should see a single
solid band appear above bottom to signify your lure. If you do not see this,
adjustthesonarSensitivitybypressingtheSENS/ZOOMbuttonandthen
theUP/DOWNkeys(seeSENSITVITY).Adjustsensitivityuntilyoucanmake
outyourlureevenasyoureelituptowardthesurface,orjigitupanddown.
Do not increase sensitivity too much, however, as doing this may cause your
Showdown Troller to display excess “clutter” that makes following your lure
and nearby fish more difficult.
Battery life and sonar run-time: Using6AAbatterypower,20hoursof
continuous use can be achieved.
With the use of the Optional 12V Performance Pack and Optional 12V battery,
afullycharged12-volt,9.0-ampbattery(notincluded)shouldprovideup
to 30-hours of use between charges. To avoid an unexpected shortage of
power, always have a spare set of AA batteries with you. NOTE: In ICE mode,
whetherusing6AApoweror12Vpowerthroughtheoptionalperformance
pack, run time will be decreased slightly, due to the power requirements of
the LCD heater. To assure long battery life, and peak sonar performance, we
recommendcheckingyour6AAbatteriesoftenandchargingyour12Vbattery
after every use.
Will the Showdown Troller read through the ice?
Yes. This is a great way to save time while looking for a particular spot or
depth.Toreceiveasonarsignaldirectlythroughtheice(withoutdrillinga
hole), first clear off any snow that may be covering ice. Make sure that ice in
the area is relatively “clear” ice without excessive bubbles or frost pockets,
which can deflect sonar signals. Pour about a cup of water on the spot,
and immediately rest the transducer on the standing water on the ice. If the
surface of the ice is rough or filled with air bubbles, drilling a 1” deep hole in
the ice before checking the depth may be necessary.
Caring For Your Showdown Troller
To keep your Showdown Troller running at optimal performance, we recom-
mend the following: Stow your Showdown Troller properly when not in use.
Turn sonar power off, and disconnect Power plug from back of unit. Remove
the AA batteries if storing for over 3 months. If using the Performance Pack,

with a 12 volt battery, recharge battery after every use, and during prolonged
storage periods, recharge the battery every few months. These steps will
maximize the life of your battery. To clean your Showdown Troller periodically,
use a mild dishwashing soap and a soft cloth, and gently clean the Show-
down Troller power head and view screen. DO NOT use window cleaner or
alcohol-based cleaning products—they may damage LCD screen and void
your warranty.
