[PSUBS-MAILIST] 3D dive recording, kickstarter

[Øystein Skarholm via Personal_Submersibles]

Du you know the price of these units ?
This underwater GPS unit from Blue Robotics is also an affordable solution.
It should be possible to tweek the system into reverse, so that the
position signal can be sent down to the sub acoustically.
