Technical Diving Courses – TDI
Open Circuit Courses
Intro to Tech Diving
The TDI Intro to Tech course is the perfect course for divers who have heard about technical diving and want to find out more about this exciting branch of advanced recreational diving. 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!
TDI’s Intro to Tech course is a useful stand-alone course for the diver who wants to become a more skilled, more proficient diver regardless of if he intends to move on to technical diving. The course may also be used as an introduction to the TDI Advanced Nitrox course and the TDI Decompression Procedures course. And finally, it is also a good refresher for certified technical divers who may want to refresh their skills or have them re-evaluated by a TDI technical instructor.
Nitrox Diver
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
The course follows an easy to read and understand diver manual titled Understanding Nitrox and water proof tables for quick on site reference.
Advanced Nitrox Diver
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.
Decompression Procedures Diver
As sport divers planned decompression is not something that we do or have been taught. The TDI Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal sport diving limits. Your TDI Instructor will provide you with valuable information and skills, among the topics covered are
* Kit set-up
* Equipment requirements
* Decompression techniques
* Decompression breathing gases
* Gas management
* Contingency planning
The TDI Decompressions 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. Some of the materials you will be using include the TDI Divers Guide to Decompression Procedures, US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)
Extended Range Diver
Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will 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 and with a maximum depth of 55m/180 feet you won’t have to miss those dives. The Extended Range course will cover topics and skills such as
* Equipment requirements and configuration
* Decompression options
* Use of surface marker buoys
* Buddy rescue
* Narcosis checks and management
Materials for this course include the TDI Extended Range Diving Manual and the US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)
Trimix Diver
As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 m/200 feet with a blend of helium appropriate for the planned depth. The course covers topics and skills like
* Dive team planning
* Gas matching
* Cylinder labeling
* Surface marker deployment
* Equipment configuration
* Thermal protection options
Advanced Trimix Diver
The TDI Advanced Trimix Diver course is the top level of training for open circuit divers wishing to dive to depths as deep as 100 m / 330 feet utilizing hypoxic levels of oxygen (below 17 percent). This course is perhaps one of the most informative and challenging and upon completion you are among some of the most elite divers. 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
The TDI Advanced Trimix manual is one of the most up to date manuals and includes all the latest of technology and practices being used.
Overhead Environment Courses
Cavern Diver
As the first in a series of overhead courses, the TDI Cavern Course takes a serious look at the skills needed to conduct safe and enjoyable cavern dives.
