The only and only DPV
DPVs are the most critical piece of life support equipment used by the deep exploration divers of the WKPP, even more so than the rebreathers. Rebreathers do not have the efficiency, reliability, or speed to get the job done.
The secrets and combinations that make the impossible, possible with the Gavin DPV are well documented over 10 years of use and hundred of owners, usually the lead explorers in their part of the world. The Gavin design is a product of knowing what they are doing from experience.
