It seems to me there is no advantage to depth when using the hydrophone. Even in stormy conditions, the sound guy finds all he is going to find at just periscope depth, and finds nothing more if we go deeper.
In fact, if I have a crack sound guy, he will find stuff while I am on the surface in stormy weather, just from the occasional immersion.
I also note there is no audible surface noise when I am wearing the headphones.... 15 m is as good as 50m.
