Aha! So it might be able to detect other submarines, even if they use some stealth tech.

Submarines generally have neutral bouyancy while underway so there's not much density difference to discern.

That sounds absurd, but the $5 pressure sensor on my weather station could detect a volcanic explosion 5,000 miles away.

Is there even a difference between a submarine and the surrounding water's gravitational fields when the sub has neutral buoyancy?

I'd argue that the gravity field of a sub is not uniform despite having neutral buoyancy. No idea though how significant that is vs. how sensible the measurement is

You'd have better luck trying to measure a neutron with a bathroom scale.

There probaly would be, the displacement might be the same but the distribution of mass wouldn't. But I recon these instruments are only sensitive enough to measure the difference between the seafloor and the water above.

Not even close.
