TDI Extended Range
$799.00 is for tuition only. Elearning code and student material are additional. Certain areas of the world provide spectacular dives at depths deeper than 39 metres/130 feet but you may not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas, with a maximum depth of 55 metres/180 feet. The course provides the training and necessary experience including proper techniques, equipment requirements, and hazards of deep air diving, to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.

Some of the required skills you will have to demonstrate include:
- Use START before every dive
- Stress analysis and mitigation
- Gas matching procedures
- Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
- Show good awareness of buddy and other team members through communications, proximity and team oriented dive practices
- Demonstrate competence managing 2 stage cylinders, either 2 deco gas or 1 deco and extra bottom gas, including drop and recovery while maintaining position in the water column
- Demonstrate ability to confirm gas switches at depth with buddy/team members
- Demonstrate lift bag deployment from depth and use of bag as back-up buoyancy device
- Demonstrate air-sharing ascent from depth while one member of buddy team is without mask, both as a donor and recipient
- Create contingency decompression schedule after simulated loss of decompression gas
- Remove and replace mask, deploy back up mask
- Demonstrate tired diver tow at depth and on surface; 30 metres/100 feet lateral
- Complete a horizontal breath-hold swim at depth for 15 metres/50 feet with mask off or blacked out
- Properly execute the planned dive within all pre-determined limits
- Demonstrate the proper procedures for switching and isolating a malfunctioning regulator, this skill is to be performed at a depth no deeper than 40 metres/130 feet
- Demonstrate the proper navigational techniques for the specific dive
- During 2 dives, demonstrate an ascent with ascent reel and lift bag and perform staged decompression
- During one of the dives, tow a simulated unconscious diver, while at depth, 9 metres/30 feet to ascent line and simulate an emergency rescue ascent technique
