TDI Advanced Trimix Diver Course
The Pinnacle of Open Circuit Diving – Explore 100m+
Master advanced trimix diving with Rick Kirkham in Panglao – where 100m dives start just meters from the beach.
The TDI Advanced Trimix Diver Course represents the highest level of open circuit scuba training. This is where technical divers refine their skills, discipline, and precision to safely explore depths beyond 100 meters using helium-based breathing mixtures.
At Frontier Tech Divers in Panglao, we offer a unique advantage — easy access to deep walls and drop-offs directly in front of our resort. You can literally swim out and descend into trimix depths without the need for long boat rides or logistics-heavy setups. Panglao’s deep reef faces make it the perfect natural classroom for serious deep divers.
