TDI ADVANCED NITROX + DECO/HELITROX
WHY ANILAO?
Anilao gives you real technical training environments: sheer walls, deep slopes, and iconic sites like Mapating Cave, all within easy reach of shore.
Calm days give you perfect practice windows, while occasional rougher weather teaches planning, adaptability, and true dive-team discipline — exactly what tech divers need.
From reef sharks to schooling jacks and dramatic underwater topography, Anilao delivers the sense of scale and exploration that makes technical diving worth it.

WHAT YOU LEARN
Use nitrox mixes up to 100% oxygen, manage higher PO₂ limits safely, and perform staged decompression with O₂-rich gases.
Plan and execute decompression dives to 45m using proper deco gases, ascent profiles, and helium-based mixes (if taking Helitrox).
Rock-solid gas calculations, rule-of-thirds, team positioning, lost-gas strategies, emergency protocols, and controlled ascents.
Stage handling, bottle rotations, gas switches, buoyancy under task load, long-hose work, situational awareness, and bailout-level discipline.

COURSE STRUCTURE
Complete the TDI eLearning in advance so you understand the concepts when you arrive. This maximizes water time and minimizes classroom confusion
Buoyancy refinement, valve shutdowns, bottle handling, simulated gas switches, team drills, and full equipment mastery before we add deco.2 Days
Run full ascent profiles with mock gas switches, stops, and timing — perfecting precision, pacing, and teamwork without actual decompression obligations.
Two planned deco dives using Nitrox or Helitrox as appropriate, executed exactly to plan — with full briefings, gas planning, ascent strategy, and video debriefs after every session.
We film your skill sessions, review them in detail, and even show footage during the dive using our Divevolk housing — allowing immediate correction and faster progression.
