Bathymetry is a very complicated thing really ...
But there is a very usefull tool to use it : SHIFT + I on the nav screen
With this shortcut, you could switch beetween "depth+SNR", "SNR only" and "nothing"
3 selections.
If you want to find the best place around to listen, use SNR only with SHIFT + I, and use the darkest area next to you : here you will have the best SNR you could find around, so the best listening capabilities.
If one ship is on a very dark area, and the other one is on a bright area, the one on the dark zone could detect first the other, because he is in a more quiet water and could hear at longer range, when the other have his sensor perturbated by a bad SNR.
Topography have great influence on SNR, you could see this because there is only few difference, usually but not always, beetween relief and SNR.
But it could be VERY different on some places.
I had maps where it was completly different, where dark areas were often shallower than bright areas !
One often believe that the darker the area, the deeper the water, but that's not always true, and sometimes completely false ! (see some shallow area around filipines)
So, to avoid any misinterpretation, if you look for the best area to position yourself for detection, use SHIFT + I to find the darkest area near you.
And it's not always the deeper places !
