PADI/DSAT Courses

Now Mermaids Dive Center is DSAT Trimix Diver and Trimix Instructor Training Facility, the only one in Pattaya!

PADI Basic Nitrox Diver

First you need to decide that you would like to extend your diving limits. Maybe you want to do longer dives. The PADI Basic Nitrox course shows you how to do this. We simply add a bit more oxygen to the air you are breathing, and by the process of elimination reduce the nitrogen. Therefore you absorb less nitrogen while you are diving. By using a set of adjusted dive tables we can now dive longer. Maybe you’d like to spend an hour on the Asia Pottery Wreck at 23 meters (don’t steal the pots!)? Can do!

DSAT Semi Closed Circuit Rebreather Diver

Do you want to get those U/W photos that nobody else has? The PADI Semi Closed Circuit Rebreather Course let’s you do this, and any Basic Nitrox Diver can join. The Rebreather simply re-cycles the oxygen you breath out right back to you, with a filter to eliminate the carbon dioxide. You can dive the Draeger Dolphin Rebreather for 2 hours with a tiny five liter tank - and almost no bubbles. The fish you are trying to photograph don’t even know that you are there! How about surprising a Goby or cleaner shrimp with a rare photo opportunity?

DSAT Gas Blender

Ever stop to think about the gases we breathe when we dive? In technical diving we use many different gases to optimize our bottom time and decompression obligation. The DSAT Gas Blender course teaches you to safely and accurately mix Nitrox mixtures for all levels of diving. You will be certified to blend these gases for use in diving operations. As a course option we can also introduces you to the blending techniques used for Trimix  Mix your own gases and do your technical diving with confidence!

DSAT Apprentice Tec Diver

Are you the engineering type (fiddles with everything that can possibly come apart and go back together)? Ever looked at those technical divers and wondered what all that gear is for? The PADI Apprentice Tec Diver program teaches you the basics of using double tanks, stage bottles, and other technical diving gear. Within a safe 40 meter depth limit you will practice and master all the techniques used by technical divers under the close supervision of Mermaids staff. Build the skills and confidence you need to take your diving to the next level!

DSAT Deep Tec Diver

Is there anything to see a bit deeper? The PADI Deep Tec Diver, PADI's first course in Decompression Diving, lets you use double tanks to carry more gas down to 50 meters. You can do decompression dives using Nitrox and 100% Oxygen in 2 deco tanks, so that your body is purged of excess Nitrogen very quickly. How about an exciting dive to 50 meters for 30 minutes in the Samae San Hole. Who wouldn't like to see an untouched coral reef with up to 10 meters visibility and large schools of Angelfish and Batfish? Is the legendary Samae San ammunition dump somewhere out there? This course can be combined with the PADI DPV Diver course for some amazing technical dives using the U/W scooters and double tanks - You can spend your entire decompression obligation on the reef!

PADI Instructor Training is available for qualified Instructors at all levels!

IANTD Courses

IANTD Advanced Nitrox Diver

To get even more bottom time you can take the IANTD Advanced Nitrox course. In this course we teach you how to use a tank with 2 valve openings and 2 regulators (H Valve) for greater safety in the 30-40 meter depth range. If you blow an O-ring - No Problem! We also show you how to safely perform decompression dives. By using a gas mixture of 50% oxygen and 50% nitrogen you can do short, safe decompression stops. The nitrogen in your body from the dive will quickly be eliminated through your lungs. How about a 30 meter dive for 60 minutes searching for lost dive gear off the Hardeep?

IANTD Normoxic Trimix Diver

Does exploring the Samae San Deep wall appeal to you?. The IANTD Intermediate (Normoxic) Trimix Diver course allows you to travel from 50 -60 meters along the vertical wall off Shark Fin Rock in Samae San. We do this by replacing the nitrogen in your tanks with helium.  This new gas, Trimix,  reduces nitrogen narcosis and enables you to think clearly at deeper depths. You can be at 60 meters and only feel the narcosis of a 30 meter air dive! All those Giant Stingrays sitting in the sand at the bottom of the ledge are now safely within reach of your cameras!

IANTD Instructor Training is available for qualified Instructors to Advanced EANX Level!

Advanced Trimix Diver

Advanced Trimix will involve four dives in the 60 meter to 90 meter depth range using hypoxic Trimix with O2 Decompression.
