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?

I want to see you lower the transom..............Gary
I agree with JigStix that you aren't going to see near the detail running at faster speeds, no matter where your xducer is mounted. If you're holding the bottom at high speeds, it's mounted correctly. Increase your ping speed to get more detail then read the marks just like you would have back in the days of the old flasher units. A guick flash on the screen at 20 knots could be enough rockfish to blank out the bottom at idle.
