I have a couple of man-made lakes nearby. They were natural canyons until
they were dammed. Consequently the lake is filled with submerged trees and
rocks.
I'm wondering how useful a fish-finder would be to visualize below the
surface in order to avoid submerged trees including dropping an anchor into
a tree instead of mud. I'd rather not buy a new anchor and rode everytime I
drop the hook in some quiet water.
Has my imagination created a problem that doesn't exist and tree filled
reservoirs aren't really anchor-thiefs?

Thanks
Bryan
