Matching depth of opposing submarines!

That's because you don't do it. I am a current, real-life ASW operator and do not exactly determine the depth of the opponent. You can relatively easily determine if it's deep or shallow, above or below the layer, and that's all the depth information you need. You can determine more or less exact depths in certain situations but it is not tactically useful and you certainly can't do it in DW so it doesn't matter.

You have to realize you're dealing with 1,500, maybe 2,000 feet of vertical movement at most. Submarines are not airplanes operating in a 50,000 foot envelope, so anti-air warfare thinking does not apply to ASW.

Nothing personal, but that's a minor pet-peeve I have about answering questions around here - I or Henson or some other current, serving ASW guy or submariner will provide information and no one will believe it.
