Observation crew can report upto 8km or 16km (depending on mod installed, i.e. GWX) Hydrophone crew reports upto 20km or so. But listening yourself in the hydrophone station gets you bearings from upto 34km. So the effort of doing it yourself, ever so often as desired, is well payed. But it's still mind-numbingly boring. And you can't stay submerged ( below 10m) for ever. The ocean is a really big place, so don't expect to find anything in one spot. Move across an expected traffic route for better chances, or position yourself in a chokepoint.
