A diver propulsion vehicle (DPV) is a battery-powered device that tows divers underwater, extending range and reducing air consumption. Our complete DPV guide covers how they work, what they cost, and how to choose the right one for your certification level.

⚠ Diver Safety Notice: Diver propulsion vehicles require appropriate training and certification before use. Operating a DPV without proper certification increases the risk of barotrauma, decompression sickness (DCS), and disorientation — particularly in overhead environments such as caves and wrecks. Always complete a recognised DPV specialty course (PADI, NAUI, TDI, or SSI) before operating a DPV. Never exceed your certification level.
Who Uses DPVs

Find Your Use Case

Direct Answer

Diver propulsion vehicles serve three distinct user groups, each with different certification requirements, hardware tiers, and objectives. Recreational divers use sea scooters for reef coverage and photography; technical and cave divers use aluminium/carbon DPVs for overhead environment penetration; public safety and military divers use professional-grade platforms for search, recovery, and covert operations.

From reef photographers to cave explorers — diver propulsion vehicles serve radically different missions across skill levels.

🐠

Recreational Diver

Conserve air on reef dives, cover more ground, and explore underwater photography. Sea scooters across the Entry, Mid, and Premium tiers make it accessible for reef and pool use.

Direct Answer

The DPV battery range calculator estimates run time and range based on battery capacity (Wh), speed setting, operating depth, and current conditions. Results are illustrative only — never use calculated estimates for overhead environment dive planning. Always apply the rule of thirds and carry redundant power.
