my stupid question,how to find enermy sub?

[nquantum]

Yeah! Sorry for simple stupid question huh! Sut really want some tip to find/search/hunt enermy sub. I can manage to find surface ship from passive sonar ping (from other ship) , passive town,spere sonar in sometime. And patience to get good TMA.

Bet when search for other sub. I always blind in dark room. I set random course my own sub and hope to pickup some water fall from town,spere sonar. Sometime I circle around. So it just take some time? Do u have any tip , techinique?

Do u use time accelerate on the game or not? Or not use at all?

Thank
