OPERATION
The Marcum Digital Sonar has many functions and settings that are selected
or changed by buttons on the Control Panel. Learning what each of the
buttons (POWER, SENS, RANGE, ZOOM, IR, CONE ANGLE, TARGET
ADJUST, MENU/ENTER, UP, DOWN) does will enable you to get the most out
of your Digital Sonar. Note that you can experiment with different settings and
dashboard arrangements in SIMULATOR mode. Many of the selections will
activate just by highlighting your desired setting.
Control Panel
The following is an explanation of each button on the control panel and what it
does. Some of the button functions can also be accessed in the main menu.
Pressing any of the Control Panel buttons will cause a window to open,
enabling the user to make the desired adjustments. All button function windows
will time out after about 6 seconds. Any changes made to the settings will
activate when the MENU button is pressed, or after a few seconds without
activity.
POWER
- Press and hold this button for 2 seconds to turn your unit on or off.
SENS
- The SENS (sensitivity) button controls the amount of sensitivity
required by the unit to pick up objects like bottom, weeds, fish, or lures and
jigs. The lower the number, the less sensitivity, conversely higher numbers
mean more sensitivity. To adjust your sensitivity, first press the SENS button
and a bar will appear at the bottom of your display. Pressing the UP/ DOWN
will adjust your sensitivity, and the sensitivity setting will now be digitally
displayed on the SENS gauge. The best SENS setting is achieved by turning
up your sensitivity until you receive a clear and steady bottom reading. To see
your lure or bait, turn up the SENS some more until you just begin to display
your bait without it fading or flickering on the screen. The sensitivity will go up
to 25, but you are likely to have it set considerably lower.
RANGE
- The Marcum Digital Sonar has nine different fixed ranges, as well as
the ability to create custom ranges using the Dynamic Depth feature. Pressing
the RANGE button on your Digital Sonar will open up a sub-menu with four
different range options.
AUTO RANGE
– Selecting AUTO will put the Digital Sonar into a sort of “search
mode” where it will detect the bottom and automatically lock into one of the nine
ranges [10, 20, 40, 60, 80, 120, 180, 240, and 300]. This is a feature that allows
you to simply turn on the unit and begin fishing. To enter Auto Range, press
RANGE, and use the UP button to highlight “Auto”, and the Digital Sonar will
automatically lock into the appropriate depth range. For instance, in 32 feet of
water, the Digital Sonar will lock into the 40 foot range. In 45 feet of water the
Digital Sonar will automatically lock into the 60 foot range.
MANUAL RANGE
– Selecting MANUAL will allow the user to decide which fixed
range they would like to have displayed. Highlight MANUAL, and arrow up or down to
the desired depth range.
