Basic Nitrox

Nitrox was originally viewed by the major diving agencies as dangerous. Even going so far as to call it a "voodoo gas". But as agenies such as TDI took the lead in demonstrating that nitrox can be used safely for recreational and technical diving, these other agenies soon followed suite. Nowadays, nitrox is a standard part of recreational diving. 

The TDI nitrox speciality course teaches the benefits and limitations of using higher mixtures of oxygen in your Scuba cylinder of up to 40%. There are many advantages to using nitrox as opposed to air, but additional considerations are required to dive safely on it.

The course covers:

  • Benefits of use
  • Limitations of use
  • Oxygen concerns
  • Tracking of oxygen, manually, and using tables
  • Methods of blending
  • labelling and analysing

The course can be conducted as a no-dive course, or can inlclude 2 dives, which take half a day and 1 full day respectively.

Course requirements:

  • Minimum age 18 years old (15 with parental consent)
  • Be an open water diver, or be enrolled on an open water diver course

BSAC Dive Leader

BSAC Diving in Thailand

Many BSAC divers often get frustrated with the number of dives they can do in the UK- usually at weekends. Bad weather also means that some of these diving trips have to be cancelled or postponed too. We can hardly change the weather conditions, but the frustration it can cause is understandable.

As a BSAC Centre of excellence, Big Blue Tech Thailand offers BSAC courses all the way up to dive leader. As we dive every day of the year, and have warm tropical waters on our doorstep, these courses can be completed in a matter of days for ocean diver, and just a few weeks for dive leader. This is a great solution for those BSAC divers that really want to progress a little faster than the conventional route.

A BSAC Dive Leader is an equivalent qualifiation to the PADI and SSI divemaster programs. A BSAC dive leader is considered competent in planning dives for groups of divers and managing those dives and, if necessary, managing rescue situations. The dive leader course is comprehensive, consisting of a mix of classroom-based and practical lessons that give divers confidence to plan, lead and manage dives, and deal with emergencies. Leading a dive increases enjoyment, confidence and experience as a diver. Upon qualification, and if desired, depth can be built progressively to a maximum of 50m. Dive Leaders are also eligible to progress to Open Water Instructor.

Big Blue Tech Dive Leader program

The dive leader course can be completed in two weeks, and consists of 12 classroom lessons, 7 open water dives, 2 dry practical lessons and 20 dives (which may include the open water lessons), in a range of conditions. The course covers the role of the BSAC Dive Leader, Dive Planning and Management, Delayed Surface Marker Buoy (DSMB) use (midwater deployment), dive leading demonstrations, basic life support with Oxygen administration and practical management of diving incidents, casualty assessment, dive planning, shot recovery by simple lift and review of rescue skills. The cost of the program is 30,000 baht; around 600 pounds, and includes all dives, and equipment. If you can fit more dives in during the two weeks, or are planning on staying longer, you won’t be charged any extra!

The one thing we cannot offer is cold water.. sorry about that! Once back in the UK, we recommend that dive leaders practice their new skills in with other dive leaders or more senior divers, in order to ensure they are competent in cold water and bad visibility. 

Solo Diver


Whilst most dive resorts around the world don't allow people to go solo diving, there are times when, for instance you live by the sea and have no-one to accompany you on a shallow shore dive. Solo diving has historically always been frowned upon, but in recent years attitudes have slowly changed, due to the major diving agencies beginning to offer specific courses for diving by yourself.

The SDI speciality course is very thorough, and discusses equipment issues, gas planning, pros and cons of the buddy system, stress management and self rescue. Managing risk is also a big part of it, as is knowing when solo diving is and isn't appropriate. 

The theory and techniques that you will learn on the course are invaluable to any diver. Even if you don't think you will ever go solo, the course will make you a much more attentive, aware, and capable buddy. If you are an underwater photographer or videographer it is simply a must-do course.

Course outline:

  • Theory sessions
  • Equipment workshop
  • 2 days
  • 2 dives

Course requirements:

  • Minimum age 21 years old
