What is it?

Technical diving can be described as diving beyond the limits of recreational diving. This generally means diving deeper than 40m, diving long enough to require decompression stops that can be performed using air, nitrox or other gas mixes. Technical diving is usually conducted with specialized equipment that differs from the recreational diving equipment. Technical divers often carry more than one cylinder and backup tanks or use Rebreathers.

Extremely advanced training is essential to make this type of diving safe and enjoyable. Cave diving is quite obviously diving in Caves? But it is so much more than that, many caves are still being discovered and they offer a brand new world and an exciting challenge to experienced divers. Caves can vary from small, short caves/caverns to complex labyrinths with huge cathedral like structures within them.

Why do it?

As an advanced diver you may want to continue your education beyond the recreational level. During your technical training you will expand your knowledge about the theory of diving: decompression theory, the human body, oxygen, technical dive equipment and advanced diving techniques.

Learn the safest way to explore the depths of world-class dive sites: Hin Muang, Hin Daeng and Koh Haa. During your training you will visit all these sites, spending much longer at depth than you have ever done before. After you’ve qualified, take what you’ve learned away and explore the depths in other oceans.

The Krabi region has world class caves and caverns both inland and via the sea (near Koh Phi Phi). Many of these caves we are just discovering and they are huge! For those interested in this type of diving we can offer an introduction to Cavern Diving at Koh Phi Phi, contact us for details.

Already certified?

We recognize certifications from PASAI, TDI, and other technical diving organizations. We offer guided technical dives to Hin Daeng, Hin Muang and Koh Haa. A speedboat is available for private charter, and we can organize live to these special lack diving sites MEo Kong ,….

DSAT Tec Trimix Diver Course

For the extreme diver ready to further explore the world of technical deep diving, the gas of choice is Trimix. The DSAT Tec Trimix Diver course takes you to the outer edges of technical deep diving, opening the door to pristine dive sites few divers – if any – ever see.

What do I need to start?

Certified as a PADI Rescue Diver or have a qualifying certification in diver rescue and accident management from another organization *. Students who meet this through a qualifying non-PADI certification need to provide proof of CPR and first aid training within the previous two years.
Certified as a DSAT Tec Deep Diver or have a qualifying certification in deep decompression diving using air/enriched air from another organization *. Students who qualify through a qualifying certification other than DSAT Tec Deep Diver must read the entire DSAT Tec Deep Diver Manual and complete the Knowledge Reviews prior to beginning the Tec Trimix Diver course.

What will I do?

The DSAT Tec Trimix Diver course is intended to extend the depth range available to technical divers trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 50 metres/165 feet in open water. The DSAT Tec Trimix Diver course is intended for technical divers certified as DSAT Tec Deep Divers (or qualifying certification from another training organization). The course extends their depth range capabilities by training them in the use of Trimix (helium, oxygen and nitrogen).


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!

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

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

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

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
  • Equipment configuration
  • Thermal protection options
