1 rich Libsyn https://www.libsyn.com 90 600 From Truk to Pandora: Kirk Krack on Tech Freediving &amp;amp; Avatar A&amp;nbsp;sit down with Performance Freediving International founder Kirk Krack to unpack the emerging discipline of technical freediving. Kirk explains how PFI’s partnership with TDI/SDI fits into the broader “all things diving” ecosystem, then dives deep into what truly separates a snorkeler, recreational freediver, spearfisher, competitive freediver, and a technical freediver. We get into the hard physics and physiology: using nitrox and high-O₂ mixes on the surface to reduce decompression stress, accelerate surface intervals, extend bottom time, and build safer safety-diver protocols—while still managing the very real risks of oxygen toxicity and DCS in repetitive deep breath-hold profiles. Kirk shares field experience from Deja Blue safety operations, long scooter dives in Truk Lagoon, and over 250,000+ technical freedives on the set of Avatar: The Way of Water. If you’re a tech diver, CCR diver, or advanced freediver curious about applying gas management, ppO₂ limits, and decompression thinking to breath-hold diving, this is your gateway episode into the world of technical freediving. &amp;nbsp; PDR 3.0: POD DIVER RADIO http://poddiver.libsyn.com <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/20368007/height/90/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="90" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/content/110638964
