Our Affiliates

In Indonesia, our primary collaboration is with Blue Marlin Dive Tech on Gili Trawangan. Will played a key role in setting up and managing operations. This facility features a dedicated tech boat, an air-conditioned tech room, and a full array of rental equipment. Everything from CCR hire to stage rigging and regs are available. Situated in a favoured destination known for its quality restaurants, beaches, and breathtaking dive sites. Gili Trawangan remains a favourite among all kinds of travellers.

We proudly affiliate with Lagoona Divers (formerly Team Blue Immersion) for open circuit and CCR training, boasting superb equipment rental, tanks, sofnolime, and accommodation. Their well-maintained facilities, including dedicated tech rooms, are just a 15-minute drive from the town center and offer a private beach with stunning bay and mountain views. For more details, you can read my blog on our November 2021 trip to assess Andy and Kerstin’s new facility. Additionally, there are plenty of restaurants, activities, and relaxing spots for non-diving days.

Excitingly, we’ve joined forces with Bob and the crew from Shakti for the next couple of years. As one of the pioneering Raja Ampat liveaboards, they enable us to craft a truly unique itinerary for technical divers in this phenomenal part of the world
