Specialty Wreck

Wreck-diveThe lure of exploring sunken vessels, airplanes and automobiles is something most divers can't resist. The Wreck Diver Specialty course introduces you to wreck diving and helps you develop the skills and knowledge necessary for safe and fun wreck diving.

In 2010 we had our first official wreck when the Trident was purposely sunk just south of Shark Island in about 30 meters depth & in 2011 the Navy were good enough to sink one of their own retired battleships in about 20 meters depth quite literally right on our doorstep here at Big Blue.

Technical Diving

The technical diving department at Big Blue- Big Blue Tech, is run by long-term instructor Andy Campbell. The "tech shack" is located within Big Blue in Sairee village. Andy is always around to have a chat with. If you're in Koh Tao, you are more than welcome to pop in and have a chat.

What is technical diving?
Big-Blue-Tech-thailandTechnical diving is a different kind of diving that allows you to go beyond the limits imposed by diving on a single tank. You carry more gas and are therefore able to go deeper than the recreational diving limit of 40 metres. But you don't do this just for the sake of it. Some people want to explore and be able to go inside shipwrecks. Other like exploring caves. Unsurprisingly, a number of pioneering marine biologists are technical divers, as it allows them to go beyond the photic zone to collect new fish samples.

With each technical diving course you undertake, you will learn additional skills that will enable you to progress to the next level. The entry level course is the TDI intro to tech, which introduces you to the equipment configuration and gets you used to diving with two tanks on your back. You'll also learn skills similar to those learned in the open water course.

Even if you don't think technical diving is for you, the intro to tech course is really worth doing, as you will find that your buoyancy control and streamlining in the water will be hugely improved when you dive again on a single tank. It's also a very valuable course for anyone undertaking their divemaster training, as it will make you into a better diver, and a more knowledgable dive professional. Intro to tech will qualify you to dive on two tanks to the maximum depth that you are currently certified to.

Once you have learned the basics, you can progress through the courses below:

Advanced nitrox- Use additional gases as a "side-stage", containing enriched air nitrox up to 100% oxygen. Dive to 40m.
Decompression procedures- Conduct decompression dives using additional gases up to 100% oxygen. Dive to 45m.
Extended range- Dive to 55m on air, and use additional gases to accelerate your decompression stops.
Trimix- Dive to 60m by adding helium into your breathing gas.
Advanced trimix- Dive to 100m using helium breathing mixtures.
Advanced wreck- Allows full penetration into a wreck beyond the light-zone, depending on the gases you are carrying.
Sidemount- Carry two tanks on your side. Fantastic for wreck and cave diving.

If you know that you would like to do some technical diving, we have a number of packages to fit your budget. From a complete package, to lower cost speciaility packages that are tailored to suit the type of diving that interests you. You can see the full tech package here, and the speciality packages here.

For more information about technical diving, have a look at the Big Blue Tech website, and contact Andy at This email address is being protected from spambots. You need JavaScript enabled to view it.







If you've thought about making diving your life or maybe just reducing the cost of your vacations then becoming a Dive Master is the first step.
At Big Blue we treat our leadership level courses with the seriousness they deserve, while still maintaining the personal touch you just don't get elsewhere.

You'll find that there's no more rewarding experience than following the Big Blue staff through their work and becoming a part of our team.The course can be tailored to your individual needs and schedule, but remember, the more you put in, the more you will get out.

Hold your breath! FreedivingWhaleshark

Discover Freediving is your chance to get wet and experience what freediving is all about. Signing up for a Freediving Basic course is a great way to decide whether getting a freediving certification is right for you. You will learn the same skills as on the level 1 but without experiencing depth.

Duration: 1 day

Price: 3.000 Baht


SSI Freediving Level 1

Start freediving!rakelfloat500x300

The SSI Level 1 Freediving course is an introductory course with no previous experience required. In this course you learn the appropriate skills and knowledge to dive safely to depths up to 20 metres. The course includes theory sessions about freediving breathing techniques for before and after diving, a dry breath hold, relaxation, physiology and safety procedures. A pool session will include dynamic apnea (horizontal UW swimming) and depth where you will progressively learn about technique including adequate finning, body positioning and being more streamlined. The following day you go out on the boat and practice pull down and duck dive descents, equalising techniques and see how far you can go.

Duration: 2 days

Price: 5.500 Baht


SSI Freediving Level 2freedivelevel2500x300

The SSI Level 2 Freediving course is the Intermediate freediving course where the student will be introduced to further concepts for deeper freediving such as freefalling and new equalization techniques. These will improve your relaxation and conserve oxygen that consequently will help you go even deeper. The theory will give you a greater understanding of the natural changes that occur in your body when you dive called Mamalian Dive Reflex that helps you become more aquatic and how to trigger this changes faster to help you stay longer and go even deeper. You will also have a full body and specific thoracic stretching session where you will learn to improve your chest flexibility and therefore make a better use of your capacity. All these new skills will help you go over 30 meters in a relaxed, efficient and safe manner. Together with depth training you will have the opportunity to try breath holds in the water (static apnea) and continue with dynamic apnea to improve your finning and efficiency underwater.

Duration: 3 days

Price: 7.000 Baht
