The Open Water Course is designed to teach you the safety and basics of modern SCUBA Diving.

Ready to take the next step in your SCUBA education? Take the Advanced Open Water Course. It will enhance your skills and provide a guided introduction on 5 different specialties in diving, including deep and navigation.

Want to extend your bottom time and shorten that surface interval? Nitrox, the beginning of mixed gas diving, is the course for you.

This course is a combination of TDI's Advanced Nitrox & Deco Procedures classes taught together. It reduced the minimum number of dives from 8 to 6 by combining some of the fundamentals for both classes. The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.
