Tec 100 CCR Diver is the ultimate PADI Tec CCR rating. This training is significantly more challenging than the Tec 60 CCR Diver course because it includes the use of diluents and bailout gases that are hypoxic. You’ll learn to plan and make dives with hypoxic trimix/heliox using a Type T (technical) CCR to a maximum depth of 100 metres/330 feet while managing multiple bailout cylinders and completing multiple decompression stops. Very few extreme adventurers earn this rating. Will you be one of them?
