How to avoid being pinged?

As FPSchazly says it's mostly about range. Maneuver to stay a safe distance (4-5 miles) away from the pinger if you can. If you need to get closer, get a good track on him and try to pass by behind the pinger where it won't detect you, especially when you need to be more abeam of the pinger.

The Sound Speed Profile was like this one:

So I guess that shows that when you are far enough and under the layer, you will not be detected, but when you are very close, you will be.

What I feared was detection when above the layer, so I was ducking under it and hoping I would avoid the pinger, but the problem is that you cannot detect the pinger either when you are in this so-called shadow zone. So inevitably I got too close to the surface ship without knowing where it was, and so I got pinged whilst being under the layer.

From your replies I understand that it is necessary to peak above the layer at times to get a bearing and range on the pinger, and then stay about 4-5 nm clear of it. I assume while staying under the layer?
Because FPSChazly's data suggests detection possibilities from a max of 9.82 nm, which I assume is above the layer.

Cool beans, thx!

The Oscar is a huge sub! The size of the sub affects the size of the return in the game (but it's based on a lookup table, not any kind of ray tracing).

Yes, to use the Oscar detection ranges in that table would be unnecessarily conservative. Even playing as an Oscar, it's generally too restrictive. Those numbers are with as many variables eliminated as possible, including the calmest sea, a rock bottom ocean, and no layer. Change the bottom type to mud and increase the sea state and all of a sudden, these active detection ranges become greatly reduced. I can't particularly recall a time when an A.I. surface pinger had counter-detected me, and their ability to detect you is even worse in rough sea states since their sensors are where the waves are actually crashing and rolling.
