Nitrox, blended, not stired!

Compressor Operator and Gas Blender course provides essential skills for nitrox blending.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of James BenFell from his TDI / BSAC Compressor Operator and Nitrox Gas Blender Course conducted over 3 days at the Big Blue Tech – Technical Diving Centre on Koh Tao off the coast of Thailand in the Gulf by TDI & BSAC Instructor Ash Dunn.

The 3 day course consists of compressor operator technician followed by gas blender technician building directly on the skills previously learned.

The physical skills include the operation of a scuba diving compressor, filter changing and packing, filtration chemicals, oil changing, Yoke and Din valve use, emergency procedures and an indepth knoweldge of the inner workings of a compressor.

After the compressor skills were competed James discovered the world of mixed gas blending using both continuous flow methods and partial pressure. James completed the fills using a digital pressure guage and analog to get the accurate mixes followed by the lazy mans nitrox method of contrinuous flow where the nitrox comes into the compressor already mixed.

The theory for the nitrox blender course is quite substantial and involved, there’s more calculations and formulas then most would expect but being a young lad right out of school James was able to grasp the studying and methods quite quickly.

James continues on to his regulator service technician and visual inspections course to help enhance his knowledge to gain professional diving employment.

Tek Diving in Thailand

Three new technical divers join the ranks of card carrying twinset masters.

Koh Tao, Thailand

Big Blue Tech celebrate the graduation of Damien Stewart, Lin Wang and James Ferrie from their TDI Intro to Tech Course course conducted over 2 days on Koh Tao Island off the coast of Thailand by TDI Instructor Ash Dunn and assisted by Ian Jordan.

The TDI Intro to Tech Course is the entry level technical diving certification which gives the student the ability to wear a twin set with isolator manifold to their own recreational depth limit. This gives the diver the freedom and comfort of technical diving equipment with the investment of money or time in a full tech course allowing them to progress through the modular system of TDI in their own time.

Additionally this allows the students to rent a set of tech gear and continue learning at any location around the world.

The skills covered in this course include advanced propulsion techniques including the infamous backwards frog kick, gas management, isolating problems and using redundancy along with trim and control in technical gear.

The students return to the realm of recreational diving, we’re confident they’ll return soon for the next challenge.


Monsoon Season in Thailand for Technical Diving

Strong wind, big waves and ripping current prove perfect training conditions for some new technical divers.

Koh Tao, Thailand

Big Blue Tech celebrate the graduation of Eric Vinik and Sebastian Froweiu from their TDI Advanced Nitrox and Decompression Procedures course conducted by TDI Instructor Chris Haslam and assisted by TDI Instructor Ash Dunn which was conducted over 5 days on Koh Tao Island in the Gulf of Thailand.

Typically Koh Tao has idyllic conditions, perfect visibility, flat seas with sun beating down on you turning your skin into that ever desirable golden brown. However recently the weather has changed to crap with storm clouds, wind, rain and terrible visibility. For those who dive in Europe they would feel right at home. This has put a damper on the mood of the recreational divers who are looking to see the cast and crew of “Finding Nemo” but for us technical divers who are seeking the next thrill or adrenaline in our beloved sport of diving then it’s perfect for a challenge. Our motto is “Train Hard, Dive Easy” and this course covered harsh diving conditions, well as harsh as it gets for Thailand. Both Erick and Sebastian who have a lot of recreational experience mentioned that this course gave them the challenge they had been seeking for their entire diving career. Except Erik who cried like a baby because he couldn’t kick through the current with four cylinders on, but we promised we wouldn’t mention that one. (don’t worry, he got there in the end)

The TDI Decompression Procedures course enables the diver to wear technical diving equipment and conduct dives that require staged decompression up to a depth of 45m. The course covers a variety of skills but focuses mostly on the art of scheduled stops and decompression using different mixes of gas including pure oxygen and nitrox.

Sebastian moves on to Sri Lanka for some sort of humanitarian diving role for the next few months and Erik goes back to the land of gogo bars and fast food in Koh Samui to continue his work as a recreational diving instructor, however he will be back to continue his training and get more experience in the next few weeks.


TDI Advanced Trimix Course in Thailand

Divers train to 100m on helium and oxygen based diving mixes

Phuket, Thailand

Big Blue Tech celebrates the graduation of Neil Gregory from his TDI Advanced Trimix course conducted over several days diving and theory by TDI Instructor Trainer Ben Reymenants on Phuket Island on the west coast of Thailand

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.

During the course the team made a visit to Sra Keow Cave where Ben had previously explored up to 240m in vertical depth. Gregs had previously been certified as a CDAA Cave Diver and TDI Intro To Cave which allowed him to explore the stunning cave system in Krabi Province.

Ben and Gregs move on to Khao Sok National Park to complete his TDI Cave Diver course and continue with more deep dives around the sunken city and forest.



TDI Advanced Nitrox Course Completed

Technical Divers advance to Advanced Nitrox Diving in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Jennifer Cronin and Johan Arsborg from their TDI Advanced Nitrox course conducted by TDI Technical Instructor Andrew Cavell on Koh Tao Island off the coast of Thailand over 3 days with 4 dives and academic theory presentations.

This is the first (1st) stage of training in the series of TDI’s tech diver development program. The objective of this course is to train the divers in the benefits, hazards and proper procedures for utilizing Enriched air nitrox twenty one (21%) percent through to one hundred (100%) percent oxygen for dives not requiring staged decompression. To a depth of forty (40) msw, one hundred thirty (130) fsw.

The course enables the certified diver to use enriched air nitrox to extend their no decompression limits by swapping gas to higher blends as the dive continues and becomes shallower. This gives the diver no decompression obligation and longer deeper dives than experience before.

This course is also a pre-requisite to decompression diving which the students will start in a few days.


SSI TXR Advanced Nitrox and Technical Foundations in Thailand

SSI (Scuba Schools International) TXR (Technical Extended Range) course delivered in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation Rikki Clarke, and one of our very own Recreational Instructors Dan Bolton, from their SSI TXR Advanced Nitrox and Technical Foundations courses conducted by Helen Artal and Yvonne Fries.

The combined courses were conducted over 5 days, and are the perfect introduction to Technical Diving. On land the students learned about advanced dive planning, gas requirements and oxygen management, as well as taking a deeper look into the physics, physiology, equipment, and decompression theory that are involved in Technical Extended Range Diving.

In the water the boys were taken back to basics in the confined session to get to grips with their new equipment, and learn the various skills required for the course. They then completed 6 open water training dives to depths between 30 and 42 meters using both air and nitrox, and executed dive plans including up to 15 minutes stage decompression.

The combined Advanced Nitrox and Technical Foundations course is ideal for divers looking to increase their knowledge and safety in the water, while extending both your depth and no-deco limits, in addition to giving you an introduction to Decompression diving.

Scuba divers learn how to handling rich mixes of oxygen for technical diving.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Dave Mitchell and Martin Edvardsson from their TDI Advanced Nitrox course conducted over 2 days on Koh Tao Island in the Gulf of Thailand.

Ok, by now you already know the benefits of nitrox, and no-doubt have been using it successfully for some time, but now we need to help you move onto the next level; the TDI Advanced Nitrox Course. Whereas up until now you have always used just one breathing gas from start to finish throughout your dives now you will learn to take advantage of an alternate nitrox mix during your ascent.

This course examines the use of air and the full scope of nitrox mixtures to depths not in excess of 40 metres. The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing air, EAN22-99 and oxygen for dives not requiring staged decompression.

Both divers had already completed their TDI Intro to Tech and gained valuable experience and time in technical diving gear allowing them to excell at the skills and requirements which left more time for diving!


Deep Decompression Scuba Diving

Technical divers train on underwater skills for decompression diving.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of James Foleher from his TDI Decompression Procedures course which was conducted over 3 days with the final days on a our local wreck.

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 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. 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)

James progresses on to his TDI Extended Range course next week in the next step in his internship.
