First turn off the fish ID and learn to run the unit on manual mode. May
need to turn down the gain, or turn up the gain depending on conditions.
The fish ID shows most things not on the bottom as fish. And in SF bay and
the delta, there is lots of fauna in the waters.

LOL... I have a small one I use for a depth finder and it does the same
thing. I never did believe it. I was amused to see a big expensive,
color,
multi-layer, side view unit doing that too.
Does anyone have one that they believe works?

Set it up in an empty swimming pool. If it still shows fish, you can at
least get a refund or exchange.

I was fishing with a friend last night that bought a new LCD screen
fish
finder. It was showing fish all over the lake. We went to a clear
spot
where I could see to the bottom and I watched under the transducer.
It
was
still showing an occasional fish but I didnt see ANYTHING. This thing
was
pretty expen$ive. Not running demo mode or anything, reading depth
accurately. Are they all like that?
