Big Blue Tech - Thailand's Premier Technical Diver Training Centre

Technical Diving Instructor

Big Blue Tech is a TDI 5 Star Instructor Development Facility meaning we're qualified, certified and trainer to develop and educate future technical diving instructors and divemasters. The road to becoming a technical instructor requires focus, determination and ability. We provide the experience, instruction and guidance to being all the elements together creating a safe and capable technical diving instructor.

Becoming a technical diving instructor requires a well rounded amount of diving knowledge and experience. Consider taking a gas blending or service technician course to help you handle situations in remote areas.

Many of our courses can be combined with a custom tailored internship which will give the student hands on teaching experience immediately after completion of their course.

TDI Nitrox Diver

This is the entry-level certification course for recreational divers wishing to utilize enriched air Nitrox (EAN) as a breathing gas. The objective of this course is to train divers in the benefits, hazards, and proper procedures for using Nitrox mixes from 22 through 40 percent oxygen content.

TDI Intro To Tech

The TDI Intro to Tech course introduces students to the world of technical diving. This course is designed as an introductory course to the TDI Advanced Nitrox course and the TDI Decompression Procedures Course. The objective of this course is to familiarize students with technical equipment configurations, to enhance open water diving skills (such as buoyancy, trim, and situational awareness), and to introduce students to advanced gas planning techniques within a no-decompression context. This course is strictly a no-decompression course; students are permitted to use enriched air Nitrox (EAN) mixes, provided the gas mix is within their current level of certification. Intro to Tech may be combined with TDI Advanced Nitrox at the discretion of the instructor.

TDI Advanced Nitrox

This course examines the use of EAN-21 through 100 percent oxygen for optimal mixes to a depth of 40 metres / 130 feet. 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.

TDI Decompression Procedures

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.

Alternative Course is the TDI Helitrox. Students are restricted to mixes containing maximum 20% Helium and minimum 21% oxygen

TDI Extended Range

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.

TDI Trimix

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).

TDI Advanced Trimix

The TDI Advanced 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 (O2) mixtures during decompression to a maximum depth of 100 metres / 330 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.

TDI Advanced Wreck

This course provides training and experience to competently conduct advanced wreck dives. This program includes penetration skills and techniques. Depths shall not exceed the level in which the diver is trained and competent, but in no case shall the maximum depth in this program exceed 55 metres / 180 feet. The objective of this course is to train divers in the proper techniques, equipment requirements and hazards of wreck diving.

TDI Cavern Diver

This course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; in addition outlines specific hazards associated with cave diving. The cavern diver course in not intended to provide instruction for cave diving environments. The objective of this course is to train divers in the proper planning, procedures, techniques and hazards of cavern diving.

TDI Intro to Cave

This course is an introduction to the basic principles of cave diving utilizing a single primary guide line. Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern diver course. This introduction to cave diving is not intended to train divers for all facets of cave diving. The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.

TDI Full Cave

This course is the third stage of training in the series of TDI's Cave Diver development program. Advanced cave dive planning, the practical execution of different types of cave systems and scenarios divers encounter are presented. This cave diving course is not intended to prepare divers for evaluating all facets of cave diving. The objective of this course is to expand and critique previous skills accomplished in the TDI Cavern and Introductory Cave Diving programs. Emphasis is placed upon dive planning and skill perfection through actual cave penetration.

TDI Air Diluent CCR

This is the entry level certification course for divers wishing to utilize a closed circuit rebreather (CCR) for air diving. The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills to a maximum depth of 30 metres / 100 feet / using air as a diluent. No decompression diving is allowed on this course

TDI Air Diluent Deco CCR

This is the second level certification course for divers wishing to utilize a closed circuit rebreather (CCR) for air diving. The objective of the course is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop basic CCR diving skills to a maximum depth of 45 metres / 150 feet using an air diluent for formal decompression diving.

TDI Mixed Gas CCR

This is the intermediate level certification course for divers wishing to utilize a closed circuit rebreather (CCR) for mixed gas diving. The objective of the course is to train divers in the benefits, hazards and proper procedures for mixed gas diving on the unit specific CCR, utilizing a mixed gas diluent containing 16 percent or greater oxygen, and to develop intermediate CCR diving skills appropriate to technical diving to a maximum depth of 60 metres / 200 feet.
