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 fish, baitfish, insects, plank-
ton, etc.), or your lure. Thicker, or more solid bands, imply larger objects, such
as game fish. Stronger or denser objects return a stronger signal back to the
transducer than smaller objects.
