Become a qualified rebreather scuba diver with our CCR courses.

Cave diving is the pinacle of our technical diving courses.

Technical diving courses from OC Advanced Nitrox and Trimix to CCR rebreather.

All our Technical scuba diving courses and Tec diving specialties.

Technical diving courses Below are listed all our tec diving courses, but before to jump to the scuba diving "dark side", you can give it a try!
You can dive fully geared with a technical diving gear on our special "Discover Tec" or "Intro to Tec Diving" programs, because after all, you do not know if you will like to become a technical diver.

Technical diving is not "hard," like many scuba divers thought, as a matter of fact having twin tanks on your back or side-mounted will put yourself in a safer position (horizontal) more naturally than a single tank.
But most important you will have an exceptional knowledge of diving, physiology, and physics than anyone else in the recreational diving domain won't have.

A tec diver does dive its dive tables. During a technical diving course, you will learn to do your decompression tables as you will be able to do decompression dives. As a matter of fact, a tech diver does not need a diving computer, just a bottom timer.

Overall tec diving allows you to go deeper, for example to visit a wreck at 80 meters (260 feet), and stay longer like 2 or 3 hours underwater if you want.
But your technical knowledge can be applied to your recreational diving like staying one hour at just 20 meters (100 feet) if you wish.

Does a tec diver need to carry all those tanks (cylinders)?

Yes, a tec diver carries many tanks (cylinders) underwater and no, underwater it's not heavy at all!
You can swim fast too. During a technical diving course, you will learn some unique propulsion skills and will understand how easy it is to move and carry many tanks (cylinders) even again a high current.

On a classic, basic and no hypoxic configuration a tec diver have a set of twin tanks (cylinders) at the back and 1 to 2 sling tanks (cylinders) on the left side, familiaryly called deco (for decompression) tanks.

The back gas (twin tanks) is the bottom gas, the gas or mixed gas you use for your dive. In the deco tanks it's usually a 50 percent nitrox's tank and an O2 (100% oxygen) tank used to accelerate the decompression time which can be cut to more than 50 percent.
For example if your decompression time using air as a deco gas, is 1 hour, with the 50% nitrox and the O2 gases it can become as short as 25 to 30 minutes of decompression time only.

Discover tec diving PADI

The PADI Discover tec diving.

PADI has a program to discover the technical way of diving with this intro to tec. Suit up with a tec diving gear and take it to the test. Once you have tried the basics of technical diving, you will know if you want to go further in technical diving and going deeper or stay longer underwater. This is a unique experience.

The SSI intro tec

The SSI intro to tec diving.

With the SSI intro to technical diving, you will make a dive fully geared as a tec diver to test if you will like to become a tec diver. This pseudo diving course is not a real course; it's a session where you will try the technical scuba diving and make one dive, just to know and test, if you will continue on the technical diving path or not.

The PADI tec 40 course

The PADI tec 40 course.

Transition from recreational SCUBA diving to technical diving and build up your knowledge and skills as you will get to gain experience in this adventure. The tec 40 course is the first level to take your first step into the world of technical diving. The tec 40 certification will allow you to dive down to 40 meters with a set of twin tanks (cylinders) and a sling tank (cylinder).

SSI XR foundation course

The SSI XR foundation courses.

The XR foundations course is intended to provide divers a piece of training to improve their skills to a high level in tec diving and procedures. The XR means Extended Range, and this course will give you the foundation to extend your scuba diving range.

The PADI tec 45 course

The PADI tec 45 courses.

Take a step ahead in your technical diving as you take the tec 45 course and enhance your knowledge and skills to go further with a new set of mixes to use for deepening your adventure. During this course, as you improve your skills, you will also learn how to accelerate your decompression time with different Nitrox.

The SSI XR diving course

The SSI XR diving course.

TTake your technical diving to the next level to independently plan and extend your bottom time. This course will give you the thrill of exploring deep reefs, as you are staying longer underwater. With the SSI extended range (XR) diving you will dive to 45 meters deep as this course includes six dives, which are typically conducted over five days.

The PADI Tec 50 course

The PADI Tec 50 course.

Go for more and obtain a recognition on gaining a high level of skills and knowledge as you take the Tec 50 diving course to learn to dive further to enjoy the adventure. This technical diving course is the equivalent of the "old" DSAT Tec deep diver where your back gas is air and learn to accelerate your decompression time with multiple deco tanks filled with nitrox up to 100% of oxygen.

The SSI technical XR diving course

The SSI technical XR diving course.

The SSI technical XR diving course provides tec divers with the training to conduct two-gas switch, multiple-stop decompression dives to a depths of maximum 50 meters during the course, using specialized diving procedures. This course can be considered as the equivalent to the PADI Tec 50.

The PADI tec trimix 65 course

The PADI tec trimix 65 course.

Go deeper with your technical scuba diving as you take the PADI Tec Trimix 65 and learn the advantages on using a trimix normoxic (a blend of helium, oxygen, and nitrogen breathable at the surface) during a 65 meters (210 feet) dive. As you go deeper, the nitrogen will give you narcosis, so to solve this problem we replace a portion of the nitrogen gas with helium.

The SSI normoxic XR course

The SSI normoxic XR course.

Get certified to dive deeper and longer to explore the greatness of the ocean and dive at a maximum depth of 60 meters (200 feet). Learn to use a trimix normoxic gas (normoxic allow to breath the gas on the surface) to dive down to 60 meters. By replacing a portion of nitrogen with helium, your mind will be as clear as if you dive to 25 meters only, you will be at 60 meters though.

The PADI tec trimix diver course

The PADI tec trimix diver course.

Take on the extreme technical diving course as you go down deeper than 90 meters (300 feet) and be part of the elite group who accomplishes this course. This trimix course will make you a "Full trimix" diver, diving with a hypoxic gas (trimix, heliox, triox). You will also dive with hyperoxic trimix gases to learn how to compensate "the counter diffusion" effects and so much more.

The SSI hypoxic XR diving course

The SSI hypoxic XR diving course.

Go to the extreme and use all your knowledge, skills and equipment and take your adventure down to 100 meters and be certified with the hypoxic XR diving to discover the spectacular underwater world with no limits. The hypoxic XR diving course is composed of 6 dives for four days, where you will learn to use a travel gas going down because of the hypoxic and nonbreathable gas on the surface as your back gas.

PADI tec sidemount diving course

The PADI tec sidemount diving course.

The PADI Tec Sidemount course will teach you on the proper sidemount configuration. You will learn to dive with four sling tanks (cylinders) side-mounted, where two tanks are your back gas, and two tanks are your deco gas. The course can take two or more days, depending if it's a transition between a tec diver who want to swith from a "classic" back-mount gear, or if you want to learn tec diving but directly with a sidemount scuba-gear.

The SSI technical sidemount diver course.

By learning the SSI Technical Sidemount Diver Course, you will learn how to dive side-mounted with at least four tanks (cylinders) where two tanks are your back gas and the two others tanks will contain your decompression gases. The SSI Technical Sidemount Diver Course can be combined with your XR and Technical Extended Range if you prefer to start your tec path as a side-mount diver.

The SSI XR nitrox diving course.

The SSI Nitrox diving course is a particular course from SSI where you can dive with a standard recreational diving gear, but you will learn to carry a sling tank (S40, 5.7 liters type) of 50% nitrox. You will also study to do a shot decompression with an air deco table, but you will do it on the 50% nitrox as a safety measure.

The SSI cave and full cave diving courses.

Diving in an overhead environment has its inherent danger, the cave diving course, as well as the full cave diving course, will teach you how to explore properly any caves in the world. Finning techniques, cave gear, exploration reel, spools, jump and gaps, arrows and cookies will become a familiar language once you are a certified cave diver.

The SSI Technical Wreck Diving course.

The purpose of the Tech Wreck Diving Course is to provide divers the knowledge for doing deep penetrations into shipwrecks with unlimited decompression down to a maximum of 60 meters / 200 feet (during your course). None only you will learn to lay a line, but you will learn about a lost line, lost light, both (lost light and line at the same time) and the different missing diver procedures.

The PADI Tec 40 CCR rebreather course.

In the near future, the deep technical diving will be mostly made on a Closed Circuit Rebreather, as diving deep on open circuit is indeed cumbersome. All starts with the Tec 40 CCR (Closed Circuit Rebreather) course, to enter into the technical scuba diving realm. But nowadays the most uses of the different types of CCR (electronic / eCCr, and manual/ mCCR) are made by photographers because they do not produce bubbles which scare the fishes.

The PADI tec 60 CCR rebreather course.

The PADI Tec 60 CCR (Closed Circuit Rebreather) diver is the next logical step of tec diving with any type of CCRs (eCCRs or mCCRs). You will use a normoxic trimix or a normoxic heliox as a diluent (breathable on the surface). You will also learn multiple decompression stops for a maximum depth of 60 meters (200 feet) during the Tec 60 CCR course.

The PADI tec 100 CCR rebreather course.

The final training in the PADI Tec Closed Circuit Rebreather is the Tec 100 CCR Diver course. The training includes the use of hypoxic trimix and heliox as a diluent and as a bailout. You will learn to plan and dive hypoxic gases on any CCRs (eCCRs and mCCRs). The maximum depth during the Tec 100 CCR diver course is 100 meters (330 feet).
