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,
