Intro to Tech Diver
The TDI Intro to Tech Course is an introductory course that expands on recreational training by improving dive planning methods, in-water skills, and streamlining existing gear configurations in a controlled and fun learning environment.
Prerequisites

Advanced Nitrox Diver
This course examines the use of EAN-21 through 100 percent oxygen for optimal mixes to a depth of 40 metres. The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21 through 100 percent oxygen for dives not requiring staged decompression. TDI Decompression Procedures or the Intro to Tech may be combined with this course at the discretion of the instructor.
Prerequisites

Decompression Procedures Diver
This course examines the theory, methods and procedures of planned stage decompression diving. This program is designed as a stand-alone course or it may be taught in conjunction with TDI Advanced Nitrox, Advanced Wreck, or Extended Range Course. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 metres / 150 feet unless taught in conjunction with the TDI Extended Range Course. The most common equipment requirements, equipment set-up and decompression techniques are presented. Students are permitted to utilize enriched air nitrox (EAN) mixes or oxygen for decompression provided the gas mix is within their current certification level.
Prerequisites

Extended Range Diver
This course provides training and experience required to competently utilize air for dives up to 55 metres / 180 feet that requires staged decompression, utilizing nitrox mixtures or oxygen during decompression. The objective of this course is to train divers in the proper techniques, equipment requirements, and hazards of deep air diving to a maximum of 55 metres / 180 feet utilizing nitrox mixtures or oxygen for staged decompression.
Prerequisites

Trimix 60 Diver
The TDI Trimix course provides the training required to competently and safely utilize breathing gases containing helium for dives that require staged decompression, utilizing nitrox and / or oxygen mixtures during decompression to a maximum depth of 60 metres / 200 feet. The objective of this course is to train divers in the benefits, hazards and proper procedures of utilizing custom oxygen / helium / nitrogen mixtures as breathing gases. Gas mixes are not to have any less than 18 percent oxygen (O2).
