WANT TO DIVE SILENTLY?

TDI Nitrox course is an entry level course for divers wishing to utilize enriched air nitrox as a breathing gas. Little else has impacted recreational diving more than the introduction of nitrox, allowing more time underwater. During this course, you will learn the benefits, hazards and proper procedures for diving with EAN 22 to EAN 40 your TDI Instructor will also cover:

• Equipment considerations
• Cylinder labeling
• Analyzing of Nitrox 

This course walks students through the special techniques, planning procedures and skills that set technical diving apart from traditional sport diving. It will show them how to improve their dive planning methods, in-water skills and streamline their existing gear configuration, in a non-threatening and fun learning environment. The specific skills this course will highlight are:

• Advanced Buoyancy Control
• Gas Management
• Situational Awareness
• Trim
• Gear Configuration and Selection
• Many More!

The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 within your current certification level to a maximum 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. The course cover topics like:

• Equipment requirements
• Dive planning
• Oxygen tracking
• Blending methods

One of the major limiting factors of going deeper is narcosis; this course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. You will learn how to plan and execute dives utilizing as little as 18 % oxygen and diving to maximum depth of 60 m/200 feet with a blend of helium appropriate for the planned depth. The course covers:

• Dive team planning
• Gas matching
• Cylinder labeling
• Equipment configuration
• Thermal protection options

The TDI Advanced Trimix Diver course is the top level of training for open circuit divers wishing to dive to depths as deep as 100m / 330ft utilizing hypoxic levels of oxygen (below 17 percent). Your TDI Instructor will teach you:

• Equipment management
• Multiple stage cylinder labeling and placement
• Complex decompression planning and contingency planning
• Dive team awareness and communication
• Gas monitoring and management
• Use of travel gasses

During this course, your TDI Instructor will teach you the proper techniques for locating and planning a penetration dive. The advanced wreck course is commonly taught with other popular TDI course such as advanced nitrox, decompression procedures, extended range, closed circuit rebreather, and trimix.

• Use of guidelines
• Overhead emergency procedures
• Redundant equipment requirements
• Locating and identifying wrecks
• Hazards of wreck diving
• Surveying of wrecks

In this course you will receive a foundation of skills and knowledge that is needed to blend enriched air nitrox for recreational divers. Upon completion, you will demonstrate proficiency in blending enriched air nitrox and the proper labeling of nitrox cylinders. 

• Responsibilities of the gas blender
• Oxygen handling
• Gas production equipment and oxygen analyzing

Building upon the TDI Gas Blender Course, the next step is taken in the TDI Advanced Gas Blender Course where you will develop and master the skills and knowledge needed to produce custom mix gases for technical diving that include helium. After a review of academic subjects such as:

• Formulas
• Gas analysis
• Blending equipment
• Blending systems
• Oxygen handling

During this course you will be challenged and learn what it is like to work with divers during their technical diving experiences. You will learn how to manage divers, work the boat deck, and conduct enjoyable dives. Dive physics, physiology, how conduct pre-dive briefing, how to assist technical instructors as well as how to be a professional TDI Divemaster are all part of the course. Your skills will be refined to demonstration quality and your knowledge increased to that of a professional.
