Dynamic and Auto Range OFF:
This setting allows you to choose
from one of the nine ranges [10, 20, 40, 60, 80, 120, 180, 240, and
300]. Highlight DYNAMIC Scale check box and make sure it is not
selected. If it is de-select it to enter Manual Mode. Highlight the
Dynamic scale and use the PLUS/ MINUS to change the depth
range.
Zoom:
This feature allows you to focus the display on a specific
depth within the water column and can be a great benefit in a variety
of fishing situations. See “ZOOM” section below for more info on the
activating and using ZOOM.
Zoom Depth:
This allows you to select the upper range of the
portion of the water column you would like to zoom in on. Whenever
you are utilizing the ZOOM menu, keep in mind that it “times-out”
after 6 seconds.
Auto Zoom:
This feature activates Bottom Lock Zoom.
Zoom Window:
The actual size of the Zoom window can be
adjusted to four different ranges; 5, 10, 20, or 40ft scale.
Cone Angle:
All transducers send down a signal that is shaped
somewhat like a cone. Your MX-7GPS 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 “Cone Angles” below for
more information. When the MarCum MX-7GPS is first turned on, it
will be transmitting utilizing the 20-degree setting. To switch from 20
degree to 8 degree, press the MENU button, highlight CONE
ANGLE and use the PLUS/MINUS buttons to highlight the desired
selection. The cone angle changes as soon as you highlight a
selection and the Sonar Footprint on the gauge display will change
with it.
