A scuba diving scooter (DPV) can be a valuable tool for cave diving as well as other types underwater explorations.
DPVs are not only fun to ride, they extend your diving range and provide a convenient way to travel to otherwise unreachable places.
Naturally with every great thing there are complexities involved and using a DPV is no different, especially in overhead environments such as caves and wrecks. Therefore it is important to master the basics of diving with a DPV.
Read on for more about the complexities of planning a cave dive with a DPV.
- Estimating dive times
- Estimating DPV travel times
- Estimating DPV gas requirements
- Estimating task time requirements
- Estimating task gas requirements
- Estimating penetration gas totals
- Estimating time totals
- Planning/Preparing for a failure (time, gas, energy, deco, stress, navigation, silt, etc.)
There is a reason that almost all of the above bullet points begin with “estimating”. It takes a lot of practice to refine the above planning points in DPV cave diving. The primary danger with using a DPV in a cave is the possibility of traveling long distances into an overhead environment, having the DPV fail (for whatever reason) and not having a sufficient gas supply to safely exit the cave.
