I read in the manual that High Frequency sonar is what should be used to locate mines. But isn't that an active sonar mode? Is there any way to employ this with passive? Pinging away in this region does not strike me as a good choice, given that my orders are to remain undetected. So I'm confused here.

From the Sub Command manual...

Follow these steps to enable UUV active sonar.
1. Enable the wire guide controls for the UUV as described above.
2. Click ENABLE to initiate active sonar.
3. Click PRE-ENABLE to de-activate active sonar and return to passive mode.

Yes, I did read the manual on that topic after my failure. But sorry, I'm am not totally clear on how the highlighted passage addresses my question. As I asked originally,
where my dillemma lies is that:
1) I didn't even know to expect mines in that area beforehand. They were not part of my orders.
2) Hi-frequency being a mode of active sonar would potentially alert other vessels to my presence there, when
my orders are to stay undetected.
So I'm asking:
1) If there's a routine I should adopt to ascertain the presence of mines in all my regular operating cirumstances?
2) How can I do so and avoid detection at the same time?
Are you suggesting Sonar732 that I should always launch a UUV to sweep for mines before proceeding with any mission?
Or, as Pisces suggests, is it relatively safe to just go ahead and use hi-freq because it is short range? But even then, how do I know when I should use it, especially if I have no prior warning of potential mines in the area?
Seems like a catch-22 to me, so I figure I must be missing something.
