Wayne P over at BBC did a great write up about this a while back....maybe he has changed his mind because it was done I think a year or so ago.....maybe longer. I read it and it makes a lot of sense.....I come from a radar background not sonar but the principle is the same. HB supposedly has some pretty good algorithms to ID a fish....sometimes the sonar will not show fish on the screen but they are there and the software will give you an ID symbol. This same thing happens in radar systems......the target may not get drawn out on the screen but the computer sees it and gives you a hook. Wayne P had several screen images to prove his point.
