Found lots of PLBs but none that were auto activated in water.
Even found a yatching mag article which stated that while epirbs were automatic "legislation" prohibits water activated PLBs.
Automatic PLBs have been standard issue for NS Oil pax for many years. Sea Marshal is one make though there are others. Nowadays they are built into the lifejacket which for aviation is manual-inflate only.
