    New Triton Lowrance Units - Depth Issues

    I bought a new TR20x in October of last year. Used it twice before putting it away for
    winter. The depth from my thru-hull transducer gives me depth when
    idling but then it drops off when you start running. Any thoughts or recommendations?

    Not sure it certainly should. I put an thru hull on my Triton for that exact reason. Are you sure your sonar is pointed to that transducer? I would try that. It may be pulling off of the transom transducer.

    Do you have a Structure Scan transducer? If you have a Structure Scan transducer and an In Hull 2D transducer, your unit may have the 2D sonar set on Channel 2 which is the Structure Scan transducer which raises above the water line on plane thus loosing the signal.

    I never get a reading when I am running on plane, never have with any sonar. if it does it's not accurate and it will go away or in and out

    My guess would be that the transducer is mounted too far forward in the bilge. I had the same problem until I replaced mine a couple seasons ago.

    I haven’t been on in a few days. I installed it as far back as possible just to the left of center of pad. The 2 bilge pumps are just to the right of centerline. I can’t get a picture without removing the charger and the pan that covers all the pumps. Sorry

    High speed transducer solved this issue for me.
