On Santa Catalina Island off the Southern California coast, Avalon is the harbor town and the launch point for the Diver Propulsion Vehicle (DPV) Specialty at Catalina Divers Supply. This eight‑hour, two‑dive program teaches certified open‑water divers aged twelve and up how to pilot an underwater scooter to extend range, conserve air and cover reef terrain more efficiently. Catalina’s underwater scene features towering giant kelp (Macrocystis pyrifera), rocky reefs, boulder fields and sloping drop‑offs that collect fish life and create dramatic swim‑throughs. Look for bright orange garibaldi, kelp bass, schools of mackerel and the occasional California sea lion threading the canopy and investigating passing divers. The DPV course pairs pre‑course eLearning or manual study with hands‑on training in shallow water, followed by two supervised dives where you practice scooter handling, powered buoyancy, team communication and emergency procedures. Meeting point is Catalina Divers Supply in Avalon; bring a towel, dry clothes and a reusable water bottle. Prerequisites include a PADI (Junior) Open Water certification and basic comfort in cool water; minimum age is twelve. Why this is special here: Avalon offers sheltered coves, predictable dive sites and quick access from shore boat operations, while Catalina’s kelp forests and rocky geology give DPV pilots diverse routes to explore. The scooter lets you hold station for photos, follow curious fish without exhausting your tanks and bridge long stretches between pinnacles and kelp bands. Operators emphasize reef‑friendly operation — maintain horizontal trim, avoid contact with kelp and use gentle throttle changes to minimize sediment disturbance. Avalon provides easy lodging, dining and surface support, so a full day course can dovetail with an overnight stay or same‑day ferry turn‑around. For photographers the best conditions are calm mid‑morning seas with sun overhead; for training, plan on steady, cool water and bring exposure protection suited to the season. If you’re a diver in moderate physical condition, comfortable navigating currents and committed to responsible practices, the DPV Specialty here expands where you can go under power and how much of Catalina’s underwater neighborhoods you can see in a day. It’s a high‑value, high‑fun skills upgrade for anyone who wants to move faster, observe longer and return to Avalon with new routes to log on subsequent trips. Guides on Catalina commonly run short briefings about local currents, pinnacles to prioritize and wildlife behavior, and the DPV course builds conservative margins into navigation so teams can practice buddy procedures without being rushed. Bring a reliable dive computer, a modestly thick wetsuit or two‑piece system in colder months, and an attitude of patience — the payoff is access to scenes most snorkelers and many divers never reach, plus a very different, motorized way to experience Catalina’s marine life. Book early; space fills fast.
