Deep Wreck Nitrox Package Koh Chang – 3 Specialty Certifications
The Deep Wreck Nitrox Package Koh Chang is our best-selling specialty combination, perfectly integrating three essential certifications into one comprehensive training program. This powerful package includes the Deep Diver (40m certification), Wreck Diver (limited penetration training), and Nitrox Diver (EANx32/EANx36 certification) courses—giving you the skills to dive deeper, explore wrecks safely, and extend your bottom time using enriched air. Train in the Mu Koh Chang National Marine Park with access to Thailand's most spectacular deep wrecks including the HTMS Chang at 31 meters and Koho Maru 5 at 42 meters.
The true value of this 3 specialty package lies in how these certifications work together. Your deep diving skills (gas management, narcosis awareness, safety stops) enable you to safely reach deeper wrecks, while your wreck diving training (navigation, reel techniques, limited penetration) teaches you to explore these underwater structures with proper overhead environment procedures. Adding Nitrox certification extends your bottom time at depth, giving you longer to explore the HTMS Chang's corridors or the Koho Maru 5's cargo holds. Complete 5-8 training dives total across all three specialties, with each course building on the skills learned in the others—creating a powerful synergy for advanced recreational diving.
At Chang Diving, our SDI, TDI, and PADI certified instructors specialize in technical diving and bring real-world experience to your training. Learn in small groups with online theory for all three courses (no classroom time required), and train during the best conditions November-April. This package counts toward your Master Scuba Diver rating and provides an excellent foundation for technical diving courses like TDI Deco Procedures, Full Cave, or Trimix—all while saving money compared to booking the courses separately.
