    Ultrex Antenna vs. Lowrance 4000 Puck

    I am getting closer to upgrade my Fortrex to an Ultrex. I currently have a LGC 4000 puck mounted for my bow Lowrance unit. Is there any recommendation of distance between the ultrex antenna and the LGC 4000 puck? I don't know if they were too close together that you could have some sort of interference; thus, a decrease in GPS accuracy with one unit or the trolling motor? Thanks in advance!

    The Ultrex GPS (iPilot) is inside the top of the trolling motor.
    It comes with a Heading Sensor that you have to place where there is no interference from ferrous metals, magnets, or high current.

    The Ultrex puck is a compass. You can mount anywhere in the boat away from any ferrous metal. Just make sure it’s aligned with the keel of the boat.
