West Marine carried two different models of forward looking sonar. One is on
my wishlist. I can't recall the name off hand but look in their catalog in
the "depth sounder/radar" section or search their website. Was about $1000
if I recall correctly.

Is there such a commercial product or does anyone know of a custom
implementation that is documented ?

Thanks.
