hi, captians! I'm always confused when i play the Silent Hunter 3 and Silent Hunter 4, that is when you are at periscope depth, then an escort is pinging your sub,why you and your crew could not hear the ASDIC ping rebound sound when the escort found your sub. As far as i could remember, when i played the old Silent Hunter Commander's Edition, you really could hear a sonar rebound sound when the tin can caught you, which is a good warning of losing your stealth. So which situation indeed is historically accurate ?
