    I have a lowrance I finder and have a question. When trolling down at low speeds i lose speed signal and was wondering if adding an external antennae would help with speed issues?

    How low? My LMS520 (this is a puck GPS) drops off at around .30 mph. Hope this is of help to ya. -Mark

    Probably not. It’s pretty tough for most GPS units to track below 0.4 MPH SOG.

    That’s really bad. I’d probably start looking for a new GPS versus buying an external antenna.
