Are you eager to extend your underwater exploration? Whether you're a scientific diver or a photographer seeking more time beneath the waves, the TDI Advanced Nitrox Course offers a compelling opportunity. This course empowers divers to utilize enriched air nitrox ranging from EAN 21 to EAN 100 percent within their current certification level, allowing for dives up to a maximum depth of 40 meters/130 feet without the need for staged decompression.
Often paired with the TDI Decompression Procedures course, the Advanced Nitrox Course serves as the cornerstone of your technical diving journey. It provides a solid foundation for those looking to advance their skills and capabilities in the world of technical diving. Notably, TDI Advanced Nitrox is essential for both SCR (Semi-Closed Circuit Rebreather) and CCR (Closed Circuit Rebreather) divers, adding versatility to its significance.
The course cover topics like...
- Equipment requirements
- Dive planning
- Oxygen toxicity 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.
Prerequisites: Nitrox Diver certified & 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 eLearning
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:
Classroom Topics
- 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 (OOA) & 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 stops 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)
Includes: TDI eLearning code, pool practice (if needed), all required academic sessions, gas filling session and ocean sessions.
Tuition: $699
Additional fees: Boat ticket & gas fills.
