Catalina Divers Supply is the premier scuba outfitter and dive center on Catalina Island, with more than a century of combined Instructor experience.

Located at the iconic Casino Dive Park inside the historic Casino building, we are the Island’s only full-service facility offering a full range of amenities, including gear rental, gear purchase, gear servicing, and an indoor classroom. Hot showers and restrooms are available to select bookings.

For those who want to venture outside the Catalina Casino Dive Park, we are also the only dive shop on the island with a dive boat.  

We maintain the highest safety standards with rigorous air testing, and we are the exclusive source of air fills at the dive park, including Nitrox, 100% Oxygen and even Trimix.

We have a Repair Tech as well as a Photo Pro on site. This makes us the trusted choice for divers and snorkelers of all levels. Additionally, we are proud to offer Avelo, the latest innovation in scuba diving, enhancing your underwater experience with cutting-edge technology.
