beginner question on how to increase the target confidence level

I'm only speculating, but I'm imagining the reasoning could deal with the fact that in shallow water, the bottom is easily accessible and constantly at varying differences as you're steaming around. Another possible reason is that shallow water is probably much more turbulent and random compared to the open ocean that mostly has just a consistent current, in terms of the toweds getting tangled.

As a real-life advice
I would understand that. But if this entanglement realism isn't modelled (I doubt it is) then it shouldn't be mentioned, especially a manual errata.

Could it possibly have to do with noise produced if the array touch the bottom? 2 array on the bottom ar noiser than just one

I mean, if the in-game effects of a TA on the bottom is not only the obvious washout of the array itself but also a slight production of noise (in the broadband spectrum I suppose) for the boat itself.

The errata specifically says you cannot use both at the same time. So the noise of the other does not, or cannot if it speaks the truth, add together to the one that is selected.

And realistically speaking, the own noise perceived by a dragging sensor would be much stronger than what is perceived from a nearby dragging sensor a couple of yards away. As the distance of where the sound comes from is much more nearer, and thus stronger. Sound levels (decibells) do not really add anyway, as they are really fractions or ratios.

Yes, I concur, but I was speaking about an increment in Ownship Passive Source Level -- aka you produce more noise and that increases the risk to be counterdetected... Still your observation about the fact that two sound levels in decibel doesn't simpy add up still apply, so I suppose that one VS two TA running against the bottom do not make a significant difference.

I suspect a dragging TA could be detected in real life depending on the speed and the distance or the receiver. But I have nothing to substantiate that claim, and no naval experience.

Also, the concern of a dragging TA is more important in terms of lack of sensors(and damage to it), than as a source of noise. You would never want this anyway. 1 or 2 TAs doesn't matter, as you'll be at a tactical disadvantage anyhow.
