I would imagine the allied system was very similar.

That device is what I consider to be "proof" that the germans knew about the FIDO.
I find it hard to believe that a device that had a 25% success rate wasn't noticed by hydrophone operators, and then reported to BdU, by the boats that survived. |
A smal problem being that FIDO was generally used on boats that were in crash dive mode and probably not in the best position to be 'listening'
