Hello Robboa,

That's exactly what we'd expect to see if there was no discernible bottom echo at all, for example from an in-hull transducer where the wet-box has leaked, or a transom-mount transducer with the boat on the trailer.

What sort of transducer do you have?
What approximate depth of water were you in at the time of the video?
