    What IS Technical Diving in 2026? IANTD explains

    In this episode of Pod Diver TV, Joe Cocozza sits down with Luis of IANTD to tackle one of the biggest questions in modern scuba: what actually counts as technical diving today? From the early days of IAND and nitrox training to modern trimix, cave diving, decompression diving, and closed circuit rebreathers, this conversation breaks down how the definition of "tech diving" has evolved — and why different agencies, instructors, and divers still see it differently. We get into: • the IANTD view of technical diving vs. "Tech Lite" • whether cave and overhead environments are always technical • why depth alone does not tell the full story • recreational trimix and progressive diver development • the controversy around recreational CCR / rebreather training • bailout philosophy, checklists, and risk management • helium costs, narcosis, and why more divers are looking at rebreathers • where technical diving may be heading next Pod Diver TV in a conversation amongst divers who are passionate about diving. If you are interested in technical scuba, cave diving, rebreathers, decompression procedures, Rrimix, or the future of diver training, this episode is for you.

    Maldives Diver Deaths: A Tech Diver explains.

    Cave Diver and diving journalist Joe Cocozza discusses the recent Maldives dive accident from the perspective of a technical diver and cave diver. This is not about exploiting tragedy or pretending we know every final detail before the official investigation is complete. It is about asking why obvious red flags in deep diving, cave diving, gas planning, training, equipment, and rescue readiness need to be discussed while the public is still paying attention. Joe talks about why "we don't know all the facts" should not become a gag order on safety analysis, how expertise in one area does not automatically make someone qualified for advanced overhead-environment diving, and why the diving community needs to be more direct when lives are at stake. Key topics: Maldives dive accident, cave diving safety, technical diving, scuba accident analysis, dive planning, mixed gas diving, rescue diving, DAN Europe, rebreathers, DPVs, and the difference between compassion and silence. Chapters 00:00 — Why this Maldives dive accident needs to be discussed now 03:00 — Cave diving, technical diving, and the red flags experts saw early 09:30 — Politeness, ego, accident prevention, and why silence can cost lives Please leave a comment with your take. Agree, disagree, or challenge the analysis — the goal is to have the hard safety conversations before the next accident happens.
