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.
RANGE— The Showdown Troller is equipped with 5-separate depth ranges—
20, 40, 60, 80, and 120’. Regardless of the manual depth range setting,
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.
MANUAL RANGE— To manually adjust the Troller’s depth range, press
the RANGE/METRIC key. This will cause the digital depth markers to flash
on-and-off, indicating that the sonar has switched from AUTO RANGE mode
to MANUAL RANGE mode. While the display is flashing, press either the UP
or DOWN key to toggle between depth ranges—20-FT, 40-FT, 60-FT, 80-FT,
120FT, Pressing UP moves RANGE to the next shallower depth zone; DOWN
moves to the next deeper zone. To go back to Auto Range, press the RANGE/
METRIC key, then press the UP key (moving Range to the next shallower
setting) until the Range passes the 20-foot range by one step. At this point, you
see a flashing “A” icon instead of the FEET indicator. To return to manual range,
simply press RANGE/METRIC again, and scroll DOWN to the desired range.
METRIC— To change your display to read in meters rather than feet, press and
hold the RANGE/METRIC for approximately 4 seconds. When in metric mode,
all depth measurements, including zoom functions, will be displayed in meters.
Repeat this process to return to measurements in feet.
NOISE (Interference Rejection)— The unit’s Noise Rejection feature allows
you to use your Showdown Troller in close proximity to other sonar units, trolling
motors, and other electronic devices without experiencing excessive signal
interference. A ten (10) level Noise Rejection function allows you to adjust to a
wide range of rejection levels. If “noise interference” occurs, increase the Noise
Rejection level until you effectively eliminate the signal interference. To adjust
the Troller’s NOISE Rejection control, simply press the NOISE/BATT button
once. The message
“noi” will start to blink at the bottom of the screen, followed
by a number. This number indicates the level of NOISE rejection you are at.
Pressing the UP or DOWN button at this time will change this number and
your level of noise rejection. Continue to adjust until interference is eliminated.
After approximately 5-seconds, all noise rejection data will disappear from the
screen, but still be active.
BATTERY STATUS— Press and hold the NOISE/BATT button for approximately
4 seconds and your battery status will appear, reflected in a percentage of
0-100 at the bottom of the display. This status indicator will disappear after a
few seconds.
