    Echo map 73dv gt20 Transducer problem

    Maps and traditional sonar work fine, but I’m getting a very weak return on downvu.. barely recognizes bottom and not picking up any previous marked structure that I used to see.. reset settings, unplugged and replugged cords.. I’ve got a new transducer on order... any other suggestions?

    Run the contrast and brightness up to at least 75. At this depth Gain on auto medium should be good enough. You already have a new transducer on order to you probably diagnosed the situation correctly.
    My wife asks if I'm going to fish every day. I can't fish every day. Some days I might be sick.
