The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres/130 feet during dives hat do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like...
• Equipment requirements
• Dive planning
• Oxygen tracking• Blending methods
You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know.
Pre-requisites: 15 years old, TDI Nitrox Diver or Equivalent, 25 logged dives
Open Water Dives:
- Four dives are required with a minimum accumulated bottom time of 100 min.
- If
Advanced Nitrox is taught in conjunction with Decompression Procedures
only a total of six dives are required with a maximum depth of 45 meters / 150 feet.
- Only 2 dives from Advanced Wreck course may
be credited.
Structure:
- Technical Divers International allows instructors to structure courses according
to the number of students participating and their skill
level.
Material:
- Technical Divers International Advanced Nitrox Student Manual.
Required Diver Performance and Requirements
Maximum training depths shall not exceed 130 fsw. The following open
water skills must be completed by the student during
all open water dives:
Land Drills
- Review of Nitrox theory
- Oxygen analyzer use and calibration
- Pre-dive planning -personal gas consumption calculations, oxygen exposures and nitrogen absorption.
- CNS loading for each dive including cumulative exposure
- Proper gas labeling.
- Prep of equipment for Oxygen service.
- Program nitrox dive computer with appropriate oxygen percentage
Pre-dive Drills
Use START* before every dive START is...
- S-Drill aka: Bubble Check
- Team / buddy equipment checks
- Air / gas matching
- Route / entry & exit, planned path underwater
- Tables / depth, duration, way-points & schedule
In-Water Drills & Demonstrations
- Buoyancy control - ability to hover at
fixed position in water column without sculling
- Awareness of team members
through communication, proximity and team oriented
dive practices
- Ability to manage free-flow from primary
regulator in controlled fashion - shutdown cycle, and
switch to back-up regulator.
- Conduct appropriate safety stop while maintaining proper buoyancy
- Ability to share "gas" with buddy as
both recipient and donor.
- Correct body position (appropriate trim,
such as horizontal / streamlined when moving forward)
Tuition: $295.00 w/ TDI study tools & TDI certification card
Additional fees: Boat ticket, gas fills and rentals
