Seeing them in time to be able to either stop, or change course enough to miss them. Don't forget also, that quite a few US boats disappeared without any corresponding IJN or IJA reports of ASW activity, which leaves only a diving mishap, circle runner, or more likely, a mine. It's best to avoid the areas, or get one of the new sonars, which is late in the war. Some WW2 subs did participate in minefield mapping... - Go and be careful

nice idea but one cannot see very far underwater. i think that is by design.
ok, well, if i am on my own then i will just have to do what Cary Grant and Glenn Ford did.
