There are some that scan either side of the ' beam ' but yes you're right. However they would be better suited to a river or narrow estuary. Can show up clumps of weed, rocks, logs etc etc as well as all sizes of fish and in shallow water. Attach one to the hull of a small inflatable boat and work a grid pattern....I'm sure they would have thought about it or actually done something similar by now though.Im sure it would if you were practically on top of the person. Side scan sonar is much quicker as it covers a much broader area and to greater fidelity.
