To charge the battery, see below “Battery Charging” section. The
MarCum MX-7GPS will operate for up to 18 hours on a fully charged
battery. If you are going to be in a situation where you will want to
use your system for more than 18 hours without recharging, having
a second, fully charged battery with you is cheap insurance that will
allow you to get full use out of your system for the duration of your
trip.
Inside the MarCum MX-7GPS’s soft case is an electronics shuttle
that has compartments for the battery and the dual beam
transducer, as well as a transducer arm. The adjustable transducer
arm allows for maximum flexibility in positioning the MX-7GPS
around the ice hole and can even be moved to the other side of the
shuttle if desired.
Using the MarCum MX-7GPS can be as simple as turning it on—the
factory settings will come on automatically and allow you to use the
MX-7GPS in the most popular configuration.
Be sure to explore all the options available to customize your
Dashboard Display. With five different sonar portals, four color
palettes, two cone angles, and a myriad of other settings, there are
many possibilities. Changing your settings is easily done on the fly
but experimenting while using the simulator at home will help you
learn the “flow” of the menu and settings.
BATTERY CHARGING
Your MarCum system comes with a 3-stage battery charger. This
style of charger has proven to be the most effective and easiest to
use of all charging systems available. Because this is a 3-stage
charger, there is no danger of overcharging your battery. When
properly cared for, a LiFePO4 battery will last for 2000 charge
cycles. Batteries are made to be used, and they need to be used to
make the most of them. The most important thing you can do is to
promptly recharge your battery after each use. Not charging your
battery immediately after use is the number one thing that leads to
battery failure.
