CONE ANGLE
– All transducers send down a signal that is shaped somewhat
like a cone. Your Digital Sonar easily switches from a 20 degree cone angle (good
for general use) to a narrow 8 degree cone angle (good for water over 40’, or any
time you need a more precise view of what is below you). See the special section
on Cone Angles below for more info. A feature unique to the Marcum Digital
Sonar is the “Sonar Footprint” that displays the actual extent of coverage by your
transducer while you are fishing. This data is displayed below the cone angle icon,
and represents the diameter of the base of the transducer cone. This will keep
you constantly updated how much area is being covered by your Digital Sonar,
and will help you decide which transducer angle best suits the conditions.
When the Marcum Digital Sonar is first turned on, it will be transmitting utilizing the
20-degree setting. To switch from 20 degree to 8 degree, simply press the CONE
ANGLE button once and use the UP/DOWN buttons to highlight the desired
selection. The cone angle changes as soon as you highlight a selection and the
Sonar Footprint will change with it.
TARGET ADJUST
– This feature allows the angler to change the size of the
signals being displayed without increasing the sensitivity. The TARGET ADJUST
feature will give you the smallest, signal size at “0”, and the signals displayed will
get thicker as you increase the TARGET ADJUST. This feature should be used in
conjunction with the SENS to fine-tune your display. Those who have a hard time
seeing, as well as those who fish from a standing position will really appreciate the
“TARGET ADJUST” feature.
BATTERY METER
— This gauge indicates the voltage currently being
produced by your battery. The Marcum Digital Sonar needs at least 11 volts
and preferably over 12 volts to properly operate. If the voltage drops below
11 volts, you may see a decrease in performance. Recharging your battery
after each use will maximize the life of your battery, and will ensu re that your
Digital Sonar will run strong all day.
MENU/ENTER
— This button enables you to access other functions of the
Digital Sonar. Some of these functions are also accessible through the use of
the other buttons on the Control Panel. When you press the MENU button,
three sub-menus will be revealed—SONAR SETTINGS, DISPLAY OPTIONS,
and SYSTEM SETTINGS.
Use the arrow buttons to highlight the desired sub-menu, and press MENU
again to access to the sub-menu.
