Deep Planet Tech is a technical diving school based on Koh Lanta and Koh Tao, Thailand. Created to cater to the expanding market of technical diving, we make use of training on two of Thailands most beautiful islands (consisting of Koh Lanta Yai, Koh Lanta Noi and Koh Tao), and some of Thailands best diving. You have the opportunity to do technical diving with some of Thailands most spectacular marine life - mantas and whale sharks. We dont believe that technical diving should always be done on the sand! On a technical diving course with Deep Planet Tech we guarantee diving at some of Thailands best diving spots - Hin Muang / Hin Daeng and Koh Haa, for no additional cost. you could also become certified at Thailands top diving destination - the Similan Islands. As well as reasonably priced DSAT and TDI technical diving courses at Deep Planet Tech you can take advantage of Thailands cheap food and accomodation on one of Thailands most beautiful and unspoilt islands. during your technical diving course you can survive in basic accomodation for as little as 200 baht per day, right on some of Thailands most stunning beaches. Thailand is the perfect place to learn technical diving, particularly the island of Koh Lanta, located in South West Thailand, home to the best diving Thailand has to offer.
If you choose a technical diving course with Deep Planet Tech, you can currently choose from DSAT and TDI technical diving courses. Whats the difference? Basically not much - both certification agencies certify you as in technical diving, the only difference is that the courses vary very slightly in skills performed and knowledge given. TDI have been around for many years (its the oldest technical diving agency there is), providing quality courses in technical diving. TDIs diving courses are very flexible, and allow the instructor to throw in as many diving skills as he wishes (as well as the core diving skills required), to ensure that the diving skills of the student are of a high enough standard. The theory portion of the TDI technical diving courses are also very flexible, with classroom presentations required to be given by the instructor. The TDI course book gives vital information, but most will come from the instructor. TDI technical diving courses are very well tried and tested over the years and have proved to be some of the best technical diving courses around. If you choose a DSAT technical diving course you will have a manual that follows PADIs excellent past record in quality training materials. the DSAT tech deep diver manual is extremely comprehensive - so much so that if you choose, you can self study the entire theory portion of the course. If your knowledge reviews are suitable then the only part of the course you need to spend in the classroom is the exams - leaving you more time for diving! Both DSAT tech deep exams are very intensive, and leave you with a wealth of knowledge about technical diving. The diving part of the course again follows PADIs track record, providing a rigid and well structured diving course.
TDI technical diving courses:

Tanks:
Normal recreational diving usually involves one tank on your back. Depending
on your air consumption rate this may be 12 or 15 litres capacity.
Technical
diving may involve the use of one high capacity single cylinder (15, 18
or 20 litres),but much more common are double tanks. The capacity you
use depends on your air consumption rate and the depth / duration
of your dive.
a
few examples...
-a dive to 50m or less with bottom time of 15 minutes,
a single 15 litre cylinder may be fine.
-a dive to 60m with bottom time of 15 minutes you could use double 12
litre tanks
-diving
any deeper or longer than this would require the use of high capacity
double tanks - 15 litres or more
Common
manufacturers of tanks include Catalina, Faber and Luxfer
|
| The
manifold system |
| Instead
of having 2 independant tanks, the 2 tank valves are linked together using
a manifold. Using the manifold means that you are actually breathing from
both tanks at the same time. This means that you have only one air supply
to monitor and one pressure gauge. The manifold has a valve in the middle
which enables you to isolate the tanks if necessary (ie in the event of
a freeflowing regulator / burst high pressure hose). |
| Decompression
/ Stage tanks |
The
tank on your back is normally for the bottom or 'working' part of the dive.
When you enter the decompression phase of your dive, you usually have extra
tanks to breathe from. A deco or 'stage' tank isn't usually bigger than
12 litres. It could also be 5 or 3 litres, depending on how much decompression
you plan to do.
Decompression tanks are rigged so that they can be clipped
to the divers BC. The diver then has the choice of keeping the tanks with
him for the entire dive, or 'staging' them for retrieval later. |
| Aluminium
or steel? |
With
most tank sizes you have the choice of aluminium or steel.
Aluminium
tanks are lighter and easier to carry, but become very buoyant when
they are getting empty. In tropical waters where your exposure protection
is fairly thin (3-5mm) its not too much of a big deal. However if you're
in cold water, wearing 10mm of neoprene or a drysuit, that extra buoyancy
could become a problem.
Steel tanks are heavy, and require more air to be
added to the BCD to obtain neutral buoyancy at depth. On the other hand,
the extra weight does reduce the amount of lead you need on your weight
belt, and steel tanks are less positively buoyant than aluminium ones
when empty.
