I am wanting to purchase a MG XI5 80 lb/no transducer option TM, but I would like to add the Pinpoint GPS option for Anchor and Jog modes. The cost to add PinpointGPS is almost as much as the version with transducer/Pinpoint GPS. Does anyone know if the add-on version of this can be stored/installed in the base of the TM? It looks like a lot of extra stuff to try to find a home for and not have just dangling out in the open, or if I can disable the transducer included easily? Going to use a Garmin 73DV on the bow and want to use their transducer.
