I always thought that a bold was a device making noise to attract the destroyers... And indeed, it seems to work like that in SH3. I never thought that it was creating a "cloud" of bubbles to stop/divert ASDIC sound...

In the film "The enemy below", the U-Boat releases a black "smoke" underwater which makes her (the u-boat) invisible to ASDIC. I don't know if it's historical.

Sometimes also in SH3, I encountered a "bug" : if a destroyer (or maybe it was a corvette) is on the point to run above you (to throw DC over your head), once you launch the bold, this destroyer (or corvette) stops immediatly and goes reverse (exactly the same way as if she wanted to avoid a collision).... :doh:

With the openings for the bubbles that are created... are done in such a way, as to allow for the decoy to spin & because of the reaction, they blast out from those openings... thereby... creating a spinning action... it gets fast enough, as it is supposed to... (no idea but would assume it worked at any rate...:hmmm:) to sound like a sub speeding up... I assume.

The whole idea was not to stop asdic, or sonar, but to make the enemy search for a U-boat... not where it was, but... where the subs skipper would want the enemy to think they were.

Think of like that weird lizard that can have its tail break off & continue to twitch around as it's there where the lizard left it... the enemy or in this case, the lizards hunter... gets focused on that twitching tail... while it gets away.

Same general principle. :yep:

M. M.

Exactly what I use it for; try to get the destroyers attention.

Okay, Do you release the Bold's at any depth?

Thank you all for your comments!

Seems like that the Game-Bold's work somewhat different than the actual/historic ones.

To me, best approach remains to stay away from late war ASW vessels, as much as possible.

Yes.

Correct. Like a lot of things in the game.:)
