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, 120-FT, 240-FT. Pressing
UP moves RANGE to the next shallower depth zone; DOWN moves to the
next deeper zone. To return to Auto Range, press the
RANGE key, and 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 will hear an audible
fast beep, and see a flashing “
A” icon above the FEET indicator.
ZOOM— The Zoom feature allows you to focus the display on a specific
depth within the water column. This position of the
ZOOM window is adjust-
able in one-foot increments. Zoom can focus on bottom (for detecting
bottom-hugging fish), or at any level above bottom. The Zoom window is
programmed to display 25% of the depth range (i.e. – in 100 feet of water, you
will zoom to different 25-foot segments of the water column).
The Showdown 5.6 Dual Beam sonar also offers Auto Bottom Track Zoom
that automatically zooms and locks onto the bottom 25-percent of the water
column. This is especially useful for locating bottom-hugging fish like walleyes
and perch.
MANUAL ADJUSTABLE ZOOM— To zoom the display in on a specific
segment of the water column, press the
ZOOM key once. Once ZOOM is
activated, the word
ZOOM will appear at the top left of the display screen.
You can now adjust ZOOM to any depth segment by simply pressing the
UP or DOWN keys—once for each ZOOM level. To ZOOM into the bottom,
simply continue pressing the
DOWN key until you reach the desired level.
To disengage
ZOOM (bringing the Showdown 5.6 Dual Beam back to normal
surface-to-bottom view) simply press the
ZOOM button a second time. The
ZOOM indicator will no longer appear at the top left of the display.
AUTO BOTTOM TRACK ZOOM— To automatically zoom onto the bottom
25-percent of the water column, you may choose to enter Auto Bottom Track
Zoom. This is an extremely helpful feature that will always lock onto and zoom
in on the bottom, even if you have removed the transducer from one area, and
placed it into completely different depth.
To enter Auto Bottom Track Zoom, press the
ZOOM key (you should see the
ZOOM icon at the top left of the screen). Press the UP key until you have
passed the shallowest depth range. At this point, you will hear an audible fast
beep, and see a flashing “
A” icon at the bottom of the screen.
NOISE (Interference Rejection) — The unit’s Noise Rejection feature allows
you to use your Showdown 5.6 Dual Beam 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 Showdown’s
NOISE Rejection control, simply
press the
NOISE button once. The NOISE indicator bar will appear at the
bottom of the screen, along with a number (0 to 10), which shows the
NOISE
control setting.
