tec diving - explore your limits!

In recreational diving you are taught to observe a set of limits which means that you dive without being obliged to make any decompression stops on the way to the surface. Technical diving allows you to go beyond the recreational limits.
If you have the desire to explore deeper or simply want to stay longer at depth then you must undertake training to acquire the knowledge and master the skills and techniques to keep you safe! We offer courses which allow you to try technical diving, take your first steps or continue your training.
Technical diving is not for everyone and requires a certain mindset, discipline and commitment. It’s not necessarily a natural progression and many accomplished divers never choose this route.
 Our technical trainers have amassed some great experience diving the deep ship wrecks in the Gulf of Thailand and Egypt too.  This is some of the hardest and intense dive training you will ever take, it will give you a new respect for diving and broaden your knowledge and experience immeasurably.

where to start?

We offer a range of courses so that you can test the waters, start on your adventure or continue your training. If you have an existing qualification and don’t know what your next step is, contact us to find out.

If you just want a little taster then have a look at the PADI Discover Tec Diving Experience or the PADI Tec Basics course.  These have the lowest entry levels, limited depths and no decompression and are just right for helping you decide if you want to take it further.

PADI Tec Deep is the “Big Daddy” of your training, qualifying you to extended depths and multi-gas decompression.  You can break this course down into three consecutive levels if you wish, offering you time to get the relevant experience and qualifications you need to complete the Tec Deep.  These courses are also ideal if you have limited time!  First is PADI Tec 40, followed by PADI Tec 45 and then PADI Tec 50.

Trimix is your next step and this will allow you to extend your limits beyond the oxygen toxicity level imposed by air.  Again this can be broken down into two stages.  The first is PADI Tec Trimix 65, which as the name suggests extends your depth limit to 65m, and allows you to dive using any normoxic Trimix blend.    A normoxic Trimix blend will have no lower than 18% oxygen  in the mix – this means essentially that it will support life at any depth.  However to go deeper you need to have even less oxygen in the blend to be safe from its toxicity.  If you are ready for this step then you will take the PADI Tec Trimix Diver course.

Closed Circuit Rebreathers (CCRs) are the diving technology of tomorrow – today !  They are becoming increasingly common place amongst the tec community – if you are serious about your diving then this is what you are using.  These super bits of kit circulate your gas, allowing you to dive both longer and more efficiently than you ever could on open circuit.

tec diving liveaboards

Master Divers has always enjoyed a long standing relationship with the tec diving community and it’s always been a base of operations for the technical diving liveaboards.  The original founders were true deep water explorers and it’s how Ayesha and Wilco first encountered Master Divers. The team set out to explore The Gulf of Thailand with the goal of discovering long lost ship wrecks.  To their credit, in less than three years they had discovered over 30 wrecks which had lain unseen for years.  The cream of the crop was the WWII Submarine the USS Lagarto but many more lie in the depths virtually undived and ripe for exploration.  You can view the schedule here and we can include trips within your training courses to give the best experience possible – contact us for package prices.

The biggest find was the USS Largarto, a WWII US Submarine lost for over 60 years. The discovery was so note worthy that many magazines wanted her story within their pages. Ayesha has been responsible for the writing and photography of the majority of features :-  Lagartos Lament for Scuba Diver Australasia, Sub Vision off Koh Tao for Diver UK and she made is into  Sport Divers 100 Essential Wreck Dives too.
