Batteries are an expendable item and must be replaced periodically.
The batteries that we use are the “LiFePO4” variety, they are 12
volts 10 amps and have a life span of approximately 2000 charge
cycles. The more amps the battery has, the longer it will run on a full
charge. Your system can be powered off any battery that is 12 volts,
even a large automotive or deep cycle battery.
If you are having difficulty with the charging process, see our
“Battery Troubleshooter” on our support site. If you need to remove
the battery, slide the power cord leads off the battery terminals.
Remove the Velcro strap that is holding the battery in place and lift
the battery out. To replace the battery, place a new battery of similar
specifications into the battery compartment and secure it with the
Velcro strap and re-connect the positive and negative terminals onto
the battery.
SETTING THE TRANSDUCER FOR ICE FISHING
When used in conjunction with the retractable pivoting transducer
arm and rubber stopper, the MX-7GPS’s transducer will
automatically level itself in your ice hole. To begin operation, take
the transducer out of the recessed holder, and rotate the adjustable
ice arm out from inside the shuttle. Extend the transducer arm, (the
cable should already be threaded through it with stopper in place)
and deploy the transducer into the water. We recommend setting
your stopper to have the transducer down the least amount
possible. The MarCum MX-7GPS puts out enough power that in
most cases it is not necessary to have your transducer down more
than a few inches below the water line to get a good reading. When
the ice thickness is over two feet, it may be necessary to have your
transducer set a litter farther down.
Remember--the less transducer cable you have out, the easier it is
to pull it out of the water when bringing in a fish, or to move to a new
location. Under no circumstances should you ever have the
transducer below the ice—this can lead to the transducer becoming
damaged.
