Technical Diving 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. I will show you how to improve your 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 they intend 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.

Advanced Nitrox Diver

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. 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 recreational divers,  decompression diving is not something that you have been taught to plan or complete. 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. I 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
  • Problem solving procedures

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.

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

Trimix Diver

As your motivation to explore progresses you will find that you may want to go deeper to dive that historic wreck  or that cave system that you have read so much about.  One of the major limiting factors of going deeper is narcosis; my TDI Trimix Diver course shows you how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course I 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. I 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.

Sidemount Diver

TDI’s Sidemount Diver specialty is the perfect course for any technical diver wishing to use this increasingly popular equipment configuration, either as a ‘stand-alone’ course or in conjunction with one of TDI’s other open circuit specialties.  I teach sidemount students how to safely utilize side-mounted primary cylinders; as an alternative to the traditional back-mounted method.
This course takes students through the specific techniques, planning procedures and skills that set sidemounted cylinder diving apart from the traditional back-mounted method.  During the course, I take students on a minimum of three dives and covers skills such as:
  • Equipment considerations
  • Gas management
  • Attaching cylinders
  • Trim and buoyancy
  • Deployment of surface marker
  • Different water entries
TDI’s Sidemount Diver Specialty is a useful stand-alone course for the technical diver who wants to become more skilled and proficient with different gear configurations regardless of if he intends to use sidemount all the time.  The course may also be taught in conjunction with any of TDI’s other open circuit specialty courses, on the condition that all prerequisites and standards applicable to both courses are fully met.
The maximum depth limit of this course must not exceed that of the student’s current certification, unless being taught in conjunction with another TDI course which allows a greater depth.  Prerequisites to enroll on the TDI Sidemount Diver course are: Age 18, SDI Open Water Diver or equivalent. (Otherwise open water diver)
