But you never know. The others may come out with something that does it better and at half the price.

Their patent probably could not stop Lowrance from manufacturing a sidescan unit. Sidescan technology has been around a long time. Patents can be overcome with a new form, fit or function. Towfish sidescan has been around a long time. It is very similar to Humminbirds stuff.
