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.

TDI CCR (Rebreather) Mod 1 course in Thailand

Technical divers study the delicate art of closed circuit rebreather diving

Koh Tao, Thailand

Big Blue Tech celebrates the successful graduation of Nick Amidy, Tony Alba and Thomas Hallstrom from their TDI Mod 1 ISC Megalodon CCR course conducted over 5 days on Koh Tao Island in the Gulf of Thailand. This course was also attended by Ben Reymenants, Simone Reymentants and Kris Harrison.

The CCR Mod 1 course is the first certification level for divers wishing to learn the safe assembly, use and diving of a closed circuit rebreather issued through technical diving certification agency TDI (technical diving international)

Military, photographic, and recreational divers use a CCR (closed circuit rebreather) because they allow long dives and produce no bubbles. Closed circuit rebreathers generally supply two breathing gases to the loop: one is pure oxygen and the other is a diluent or diluting gas such as air or trimix.

The major task of the fully closed circuit rebreather is to control the oxygen concentration, known as the oxygen partial pressure, in the loop and to warn the diver if it is becoming dangerously low or high. The concentration of oxygen in the loop depends on two factors: depth and the proportion of oxygen in the mix. Too low a concentration of oxygen results in hypoxia leading to sudden unconsciousness and ultimately death. Too high a concentration of oxygen results in hyperoxia, leading to oxygen toxicity, a condition causing convulsions which can make the diver lose the mouthpiece when they occur underwater, and can lead to drowning.

In fully automatic closed-circuit systems, a mechanism injects oxygen into the loop when it detects that the partial pressure of oxygen in the loop has fallen below the required level. Often this mechanism is electrical and relies on oxygen sensitive electro-galvanic fuel cells called “ppO2 meters” to measure the concentration of oxygen in the loop.

The diver may be able to manually control the mixture by adding diluent gas or oxygen. Adding diluent can prevent the loop’s gas mixture becoming too oxygen rich. Manually adding oxygen is risky as additional small volumes of oxygen in the loop can easily raise the partial pressure of oxygen to dangerous levels.
The course started with a session in the swimming pool where students starter to learn the fundamental skills related to all rebreathers before progressing on to open water diving.

The successful completion of the Mod course signals the start of Mod 2 where all the students progress on to decompression diving on a ISC Megalodon CCR


Introducing Technical Diving in South East Asia

Senior scuba diving instructor receives technical diving certification.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Dean Jenkins from his TDI Intro to Tech course conducted over 3 days by TDI Instructor Ash Dunn off the coast of Thailand on Koh Tao Island.

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!

TDI’s Intro to Tech course is a useful stand-alone course for the diver who wants to become a more skilled, more proficient diver regardless of if he intends to move on to technical diving. The course may also be used as an introduction to the TDI Advanced Nitrox course and the TDI Decompression Procedures course. And finally, it is also a good refresher for certified technical divers who may want to refresh their skills or have them re-evaluated by a TDI technical instructor.


BSAC Extended Range Diver Course in Thailand

British Sub Aqua Club Thailand provides technical diving certification with a edge.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Etienne De Beer from his BSAC Extended Range Course conducted over 4 days by BSAC Extended Range Instructor Trainer Ash Dunn on Koh Tao Island off the coast of Thailand.

The Extended Range Diver [ERD] course is a full technical diving qualification, enabling you to make deep decompression dives using high percent oxygen nitrox mixes [up to 100% O2] to accelerate your decompression stops during ascent.

During the course the divers explored deep rock pinnacles, a shipwreck and shallow areas for skill practice creating a variety of conditions and experiences from limited visibility to crystal clear conditions.


BSAC Dive Leader Internship completed in Thailand

BSAC (British Sub Aqua Club) provides attractive alternative to other professional diver courses with a one on one internship.

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Chris Shaw from his BSAC Dive Leader course conducted over 3 weeks by BSAC Instructor Ash Dunn on Koh Tao Island off the coast of Thailand.

The BSAC Dive Leader provides a professional diving certification and ability to work in the diving industry to experienced divers who are looking to improve their personal diving skills and learn more in-depth training and methods.

We offer several professional internship courses including the PADI Divemaster Course, SSI DiveCon Course, TDI Technical Divemaster Course and SDI Divemaster Course. The BSAC one is unlike any other professional diving level in many ways, which is what made it an attractive option for Chris.

The course focused on Chris’s diving skills and ability with one on one guidance from his instructor. This was essential since the BSAC Dive Leader course includes decompression diving, certification to 50m and oxygen administration.In addition Chris had to perform in limited visibility, at night, on a drift, from a boat and marshaling in combination with mock helicopter rescue drills.

The BSAC Dive Leader course is catered to train british divers to supervise diving activities in England but the training and confidence taught through the program in less demanding conditions meant Chris could complete the course in 3 weeks and not 6 months.

During the BSAC Dive Leader Course Koh Tao had a few days of rough weather, high seas and wind giving Chris a taste of British diving conditions as he performed the last of his training dives at our deeper dive sites on a twin set. Chris made most of his training dives in technical diving gear since he completed is TDI Intro To Tech course before starting his internship.

From this course Chris can continue his professional career in becoming an instructor or on to deeper technical diving.

TDI Extended Range Diver Course Completed

The pinnacle of deep air diving certification achieved in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of James Foleher from his TDI Extended Range Diver course which was conducted over three days on two separate wrecks in the on Koh Tao Island in the Gulf of Thailand.

As with many of the courses in the TDI training programme, this Extended Range programme serves to add more knowledge and skills to your diving development and leaves you qualified to take on more challenging and adventurous dives.

The course will reinforce much of what has been looked at on previous TDI programmes, but will go into greater depth, as well as introducing some new concepts/ideas.

This course will provide the training and experience required to competently utilize air for dives up to 55 msw (metres of sea water) that require staged decompression, utilizing nitrox mixtures or oxygen during decompression. The object of the programme is to train divers in the proper techniques, equipment requirements, hazards of deep air diving to this depth.

This certification is the maximum depth rating allowed before moving into mixed gas or trimix diving which James will participate in during the later parts of his technical internship.


Introduction to Technical Diving Course in Thailand

Scuba Divers take their first leap into technical diving in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Paw and Dave from their TDI Intro to Tech course conducted by Technical Instructor Ash Dunn and assisted by Technical Intern James Foleher during 3 days of study and diving on Koh Tao Island off the coast of Thailand.

The TDI Intro to Tech course certifies the student to use technical diving equipment and methods to their own recreational diving certification depth and limited to their personal comfort level and experience. The benefit of this course gives the students redundant air supply, more gas and allows the student to gain experience in the equipment before committing to the later and more expensive technical diver training. Many of our dive master interns have completed this course allowing them to dive daily in a “twin-set”.

This course has also taken advanced propulsion techniques and an emphasis on trim and control into account giving the students a great foundation for technical diving in the future.


SDI Solo Diver Course in Thailand

Divers learn the skills to dive solo without the need of a buddy.

solo diver

Koh Tao, Thailand

One of Big Blue Tech’s most popular courses, the solo diver program teaches experienced recreational divers how to safely dive independently of a dive buddy or strengthen your buddy team skills. The course stresses on proper dive planning, personal limitations, accident prevention as well as the benefits, hazards, and proper procedures for diving solo.  You will also learn the additional equipment that is required for solo diving including it’s proper usage and assembly. This is the prefect course for underwater photography and underwater video divers.

Big Blue Tech is the only center in Thailand offering this course and are proud to issue Dom Couture his certification. The prerequisites can be daunting for some with a required age of 21 and minimum 100 dives logged. But those with the experience can take the challenge and learn to dive without the comfort or inconvenience of a buddy.

SDI point out very clearly the faulty buddy system where it’s often a matching of people who are not equal and in many situations more experienced divers have to deal with less experienced divers who can pose a risk in certain situations.

The first training agency to offer a Solo Diving certification was Scuba Diving International (SDI) in 1999. As of 2008[update] they remain the only agency to formalize this level of diver training


Introduction to Tec Diving in Thailand

Technical diver training begins on Koh Tao

Koh Tao, Thailand – Today Big Blue Tech starts a tec course for Magnus Baer who comes from season and has been travelling for the past 4 months on a round the world trip.

Magnus has been to Koh Tao before working on the Island as a diving instructor so this would be a familiar setting for him t o learn more challenging diving.

Magnus’ tech diving course will include the ‘Intro To Tech’ , ‘Advanced Nitrox’ , ‘Decompression Procedures’ and ‘Extended Range’ modules from TDI (Technical Diving International) which is the leading and most recognized technical diving certification agency in the world. TDI’s motto of ‘We lead, Others Follow’ is indicative of their and our style of technical diving.

While Magnus joined us for specifically TDI training it was the small touches provided by Big Blue Tech which made the difference. The equipment provided for use during the course is staggering and top of the line.

Magnus was issued the following equipment today for use for the duration of his course.
–    Boots, OMS Slipstream Fins, 3mm Wetsuit
–    OMS 60lbs Double Bladder Wing with Aluminium Back plate and Comfort Harness
–    Oms Thigh Pocket, 2 lift bags, OMS Cavern Reel, Finger Reel
–    Titanium Knife, Wrist Slate, Primary and Secondary Torch
–    Backup and Primary Mask
–    Uwatec Bottom Timer and Depth Gauge
–    Suunto Vytec Ds, Compass
–    Apeks XTX 20 back gas regulators
–    Scubapro decompression regulators
–    Personal O2 tank, personal twinset, personal lean mix tank and hardware
–    OMS deco clip hardware and rigging

This is the standard equipment issued to all our students and fun divers. The choice to use this equipment has been based on years to testing other types to fail.

In addition to equipment, Magnus was taken through a refresher of his dive theory including basic physics and physiology to help bring him up to speed with the coming theoretic knowledge needed to succeed on this course.

At lunch Magnus was also taken out by James, Ash and Andy from the team for his 800m swim test which was completed under the required time of 10 minutes.

Tomorrow would be the start of the shallow water skills with his Intro to Tech course which focuses on buoyancy, trim and water control, which is a required foundation for all future technical diving.
