Chart:
This is a scrolling graph display, and it shows not only what
is happening below you in real time but will also enable the user to
have a “history” of what has happened. All of the Marcum sonars
with this feature stand apart from other graphs in that they display
with ultra-fast “True-Time” sonar response – less than .02 seconds
passes between the echo reaching the transducer and when the
signal appears on the LCD screen. When used from a stationary
position, such as ice fishing, the bottom will display as a thick, solid
band, but other signals, like fish or your jig, will display as lines of
varying thickness. Always remember that the thicker the band, the
stronger the signal. A large fish is likely to display as a fairly thick
band, while a small ice jig will show as a very fine line. When used
from a moving boat in open water, the user will see signals
displayed in classic “graph” fashion; the bottom will be a solid band,
and fish or other objects display as “arches”.
Chart Zoom:
This functions the same as the Graph display but
allows for a magnified view of a selected portion of the water
column. The ZOOM window can be adjusted by entering SONAR
SETTINGS to change your preferences.
GPS Map:
This function activates the use of the GPS features.
Turning this feature off while not in use will save on battery life as
the system is not attempting to access the satellites.
Gauges:
A feature unique to the MarCum MX-7GPS is the ability to
be able to constantly see your most critical settings. At a glance,
you will be able to see what your sensitivity level is, what level of IR
you are operating at, how high your Target Adjust is, your range,
and battery status displayed in volts. The gauges can be turned on
or off by highlighting GAUGES and use the PLUS/MINUS buttons.
Where the gauges display will depend on which screen
configuration you have selected.
