Tom MARNEFF

Diver since I was a child. Full-time instructor and rebreather diver since 2010. Passionate about underwater exploration, adventure, and discovery.

After 5 years in Mayotte where I was one of the pioneers of closed-circuit diving on the island, and a stint in New Caledonia, I am currently based in the Bouches-du-Rhône region. I am still very active abroad, mainly in the Maldives, where I spend several months a year, promoting the development of rebreathing. Rebreather instructor since 2017.

I have recently been fascinated by the M3S TRITON and NEPTUN rebreathers. Whether deep in a cave, in the middle of a school of sharks, or simply along a drop-off to observe small fish, the rebreather remains the best ally for pushing the limits of adventure.

I offer training, initiation, and crossover.
