Kirk explains how PFI\u2019s partnership with TDI\/SDI fits into the broader \u201call things diving\u201d 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-O\u2082 mixes on the surface to reduce decompression stress, accelerate surface intervals, extend bottom time, and build safer safety-diver protocols\u2014while 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\u2019re a tech diver, CCR diver, or advanced freediver curious about applying gas management, ppO\u2082 limits, and decompression thinking to breath-hold diving, this is your gateway episode into the world of technical freediving. &amp;nbsp; ","author_name":"PDR 3.0: POD DIVER RADIO","author_url":"http:\/\/poddiver.libsyn.com","html":"<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>","thumbnail_url":"https:\/\/assets.libsyn.com\/secure\/content\/110638964"}
