TDI Adv Nitrox & Deco Procedures Course

Service Description

The TDI Advanced Nitrox & Decompression Procedures (or Helitrox) Combined Course is Warrior Dive Adventure’s signature technical diving program. Designed for divers who want to push their limits, this course certifies you to dive to 45 metres (150 feet) using Air or Helitrox, and to conduct staged decompression using Nitrox 50% and 100% oxygen. You’ll learn to manage up to four cylinders, plan complex dives, and react confidently to simulated emergencies—all under expert guidance from our Trimix- and CCR-certified instructors. Why Choose Warrior Dive Adventure? Our instructors go beyond agency minimums to ensure you're ready for real-world decompression diving. Through intensive training that includes realistic failure simulations, we prepare you to stay calm under pressure and use advanced protocols with confidence. We specialize in sidemount and twinset training, gear configuration, gas switching, and redundancy-focused decompression diving—skills essential to becoming a truly self-sufficient technical diver. Why Upgrade to Helitrox? While air is still allowed for this course, Helitrox is a safer and more efficient choice. By adding helium: - You reduce narcosis at depth (lower Equivalent Narcotic Depth – END) - Improve breathing gas density and comfort - Maintain better cognitive ability and awareness - Meet requirements for cave and deep technical environments where Trimix is mandatory Who Should Take This Course?
