Hello,
an additional info, a U-boat or submarine can not be detected by surface ASDIC or Sonar when it is at periscope depth - the surface noise makes it vanish from the screen in anything else than perfectly flat calm seas, and even a very flat-adjusted detection cone will not really detect it.
Mr Topp said he almost never dived to more than 30 meters for that reason.
The real U-boat skippers considered this sim much too hard, and this was the vanilla version ... i begin to understand why my performance sucks lol.
Anyway it is fun, but real life tactics do not work here
Greetings,
