I didn't buy the camera, but I did have very clear water
when I did this test. Same thing, leaves and debris all
the way tho they looked like fish on the monitor (not the
fish symbol).
Not doubting you may have been on top of a lot of fish,
@IgotWood, but I know some of the reservoirs you fish
and there's a LOT of leaf clutter every fall/winter that
comes across this way on sonar. Granted I do not have
as nice a unit as you do, but I've been supremely frustrated
at times throwing everything at ghosts.
Once, though, I was following a school of running shad at
NNPK, got into a position where they went under my kayak
and my sonar did register them as a moving cloud - in
about 10 feet of water. So I know the sonar works
