TDI ADvanced NITROX DIVER

Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that 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. TDI Advanced Nitrox is also a must for SCR or CCR divers.

TDI extended range DIVER

Certain areas of the world provide spectacular dives at depths deeper than 39 metres/130 feet but you may 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 55 metres/180 feet, so you don’t have to miss those dives! The TDI Extended Range Diver Course provides the training and experience necessary including proper techniques, equipment requirements, and hazards of deep air diving, to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.

TDI side mount DIVER

Who this TDI course is for:
The SDI or TDI diver looking to expand their in-water skills and techniques. The certified diver who has interest in moving forward with technical diving education and expanding their equipment configuration options
Course prerequisites
Minimum age 18. Minimum certification of SDI Open Water Scuba Diver, or equivalent

TDI helitrox DIVER

The TDI Helitrox Diver Course examines the theory, methods, and procedures for planning staged decompression dives utilizing helium in the breathing mixture to reduce the effects of inert gas narcosis.
The TDI Helitrox Diver Course trains divers how to plan and conduct staged decompression dives to a maximum depth of 45 metres/150 feet. The most common equipment requirements, gear set-up, and decompression techniques are also presented during this course. Students are permitted to utilize enriched air nitrox and helium mixes with no greater than 35% helium content, and up to 100% oxygen for decompression diving. This program is designed as a stand-alone course, or it may be taught in conjunction with TDI Advanced Nitrox at the discretion of the instructor.

​Who this course is for:
Certified open water scuba diver who wants to expand diver knowledge
Certified open water scuba diver who is considering technical training
Certified technical diver who is seeking a refresher course
Course prerequisites:
Minimum age 18, 15 with parental consent
Minimum certification: SDI Open Water Scuba Diver or equivalent
Proof of 25 logged open water dives

TDI 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 metres/330 feet utilizing hypoxic levels of oxygen (below 17 percent). This course is perhaps one of the most informative and challenging of all of the TDI open circuit courses. Upon completion, you will be among some of the most elite divers, capable of doing and seeing more while diving than any other divers out there.

TDI decompression DIVER

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? 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 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression 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.

​​​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.​

TDI NITROX DIVER

TDI Nitrox Diver Course is an entry-level course for divers wishing to continue their diver education and utilize enriched air nitrox as a breathing gas to extend no-decompression limits at depth.

TDI trimix DIVER

Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The TDI Trimix Diver Course could be your next step! 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 metres/200 feet with a blend of helium appropriate for the planned depth.
