My HDS 7 works well at slow speeds (1-12 mph). It shows both bait/fish and bottom depth. However, when on plane, the depth still shows on the screen but the bait/fish fade away.
The transducer is mounted on the transom and it is flush with the hull. I was told to lower the transom just a hair and see what happens. Any suggestions?
