Problem of Omniscient Destroyers in TMO

[CptLoonee]

I will make this simple, it seems like no matter shat I do, if any destroyer gets close to me, they IMMEDIATELY zero in on me and depth charge me to oblivion.

I work very hard to end around a convoy and setup in prime position for a standard or Dick O'Kane attack, in the middle of the night, with no moon, and drop to periscope depth, scope down, run silent at all stop, using passive sonar to listen for the convoy, and as soon as the convoy gets close, the destroyers turn their searchlights on and make a ziggzagging attack run on me forcing me to perform a down the throat shot, crash diving after, and usually losing any chance of attacking the convoy.

Am I doing something wrong here?

I cannot for the life of me think of any way I can reduce my profile.

I am running TMO with the RSRD campaign.

Please help
