Dead Zone
– All sonar units will have a dead zone in certain
circumstances. This occurs on sharp drop-offs where the transmit
beam (cone) hits the shallower edge of the drop-off and returns
before the deeper edge returns. This in effect creates an
unobservable area between the shallower and deeper water within
the transmit beam. The 8-degree transducer option on the
MX-7GPS will greatly reduce this effect.
HOW TO DECIDE WHICH CONFIGURATION TO USE
With 5 different sonar windows, along with a plethora of other
settings, it can be hard to decide on which one to display. If you
have used traditional mechanical flashers in the past, you may like
the familiarity of the MX-7GPS’s flasher display. The flasher
displayed with one or more of the vertical displays is likely to be how
most anglers use the MX-7GPS, at least for starters. We get
endless feedback on how well the scrolling graph display works for
ice fishing, so be sure to give it a try. Be sure to experiment with
different color palettes and backgrounds, too.
CIRCULAR [FLASHER] DISPLAY
This sonar window will read much like a traditional flasher-style
display. You can set the range manually or allow the Auto Range or
Dynamic Depth interface to automatically lock into a RANGE that
will optimize the use of the circular display. Signals are displayed as
various colored lines on the dial with the depth and depth readout
on the inside of the dial. The different colors represent different
signal strengths depending on the color palette you have selected.
VERTICAL DISPLAYS
These sonar windows are very easy to interpret— top is the top;
bottom is the bottom. Anything in between the top and bottom is
weeds, fish, or your lure. There are two different Vertical displays—
one shows the entire water column, one shows your ZOOM window.
On each one, signals are displayed as various colored lines on the
column, and the different colors represent different signal strengths.
