I think the last device specifically cite 'listening gear' ie 'passive sonar' or headphones; the BOLD and motorized Sieglinde however deflects the sonar transmission; I don't play SH III; but based on its dual ship and air Metox capability when the real WWII metox's only detected aerial radar, I wonder about the game's AI veracity/authenticity. NOTE: I found and added more info to the above post...amazing stuff!
