    Intermittent Problems

    By Jack

    from Cape May, NJ



      • Not Durable

      Best Uses

        Comments about Garmin echo 101 Fishfinder:

        After about one month of use, the Echo 101 started having intermittent problems. The depth stopped updating, along with the graphic, and the depth started flashing. After exhaustively checking all the connections twice, with the boat out of the water, I will seek to replace / exchange this unit.
