DPV Cave Diver

The “Diver Propulsion Vehicle,” or DPV, has become an important component in technical diving. These special underwater vehicles conserve energy and allow explorers to cover long distances with ease.

The obvious draw back is that the machine can bring a careless diver quickly into danger. To avoid such errors, special emphasis is placed on gas planning, care, handling, and equipment variations.
