Discover Tec Diving
The Discover Tec Diving Experience
PADI Discover Tec allows you to try out technical diving equipment and procedures.
What you’ll learn
You will learn about technical diving and try to put it into practice. In addition, Discover Tec experiences can also be credited for the Tec 40 course.
The Diving Equipment You’ll Use
You will need basic diving equipment and try technical diving equipment.
Prerequisites
To participate in Discover Tec Diving, you must:
• Be a PADI Open Water Diver (or equivalent certification from another dive organization)

Tec 40 Course
If you’re interested in technical diving, but don’t yet qualify for the PADI Tec 50 course or the PADI Tec 45 course, you may want to consider enrolling in the PADI Tec 40 course. The latter is the first subdivision of the entire PADI Tec Deep Diver course and consists of the first four dives. From the moment you have the chance to do one of these confined water dives (such as in a pool), many divers begin Tec 40 courses during the winter months, ready to continue in open water with the arrival of spring.
You will learn how to:
- Use decompression software and dive computer to plan and decompression dives with no more than 10 minutes of total decompression and no deeper than 40 meters/130 feet.
- Use a single cylinder with a decompression gas containing more than 50% oxygen (EANx50) to increase the safety margins required during the decompression dive.
From the moment it is part of the course, your PADI Tec 40 course training is credited to you for PADI Tec 45 and Tec 50 courses.

Tec Trimix Diver Course
The PADI Tec Trimix Diver course takes you to the limits of deep technical diving, opening the door to pristine dive sites that few, if any, divers have ever visited.
What you will learn
The PADI Tec Trimix Diver course aims to increase the depth limit of technical divers already trained and qualified to use air, enriched air and oxygen for technical dives over 50 meters, with decompression. Scuba diving with trimix is at the extremes of technical diving – the maximum depth achievable with this technology has yet to be established.
The course is for Tec 50 or Tec Trimix 65 divers (or those who hold an equivalent certification from another diving organization). The course increases depth limit skills by training you in the use of trimix (a mixture of helium, oxygen and nitrogen).

Gas Blender Course
More and more people are diving using enriched air and as a result this means that the demand for enriched air refills is also growing.
Therefore, in order to meet the demand, there is a need for someone who is qualified to handle such refills. This is where the PADI Gas Blender course was born.
The latter can lead to one of these two certifications: PADI Gas Blender or PADI Trimix Blender.
What you’ll learn
The Gas Blender course will train you to become a qualified gas blender, allowing you to provide gas blends to appropriately certified users.
You will learn about the physical properties of oxygen, the risks associated with it, the requirements for its use, and the notions necessary for cleaning equipment. To conclude, you will learn the five methods of obtaining the right enriched air mixture and the various methods used to obtain the correct helium mixtures.
The Learning Materials You’ll Need
What are the four main types of oxygen? What is “clean” when it refers to oxygen? What are the five methods for mixing Enriched Air Nitrox? These questions and many more will be answered in the Gas Blender manual.
In the role of a gas mixer, you must have achieved the necessary confidence regarding the physical properties of oxygen, its various qualities of form and purity, the risks associated with it, and its special requirements for use. The Gas Blender Manual and its CD-ROM, in collaboration with your instructor, will help you familiarize yourself with the procedures and techniques necessary for gas mixing.
Prerequisites
You
• Hold a PADI Enriched Air Diver certification (or hold an equivalent certification from another dive organization)
• Be at least 18 years old
Tec Sidemount
The Tec Sidemount Diver Course
The Tec Sidemount offers the same benefits as the PADI Sidemount Diver course, but allows you to dive with 2 or more tanks, thus increasing the duration of your dives.
The Tec Sidemount Diver course is an excellent way to enter the world of technical diving, as the skills you learn will train you to handle different tanks on the same dive. To take advantage of the advantages offered by the “sidemount” configuration, also with regard to the transport of cylinders, you can combine what you learn in the Tec Sidemount Diver course with what you acquire with other “tec” courses with open circuits, or with certifications already achieved.
Prerequisites:
- Be certified PADI Advanced Open Water Diver, or hold qualifying certification from another educational organization
- Have logged at least 30 dives
- Be at least 18 years old
- PADI Enriched Air Diver certification recommended
PADI Rebreather Courses
Do you think that rebreathers are only for technical diving? Well, think again, because the latest rebreathers are lightweight and easily portable units that employ advanced electronics to simplify their use. Rebreathers allow for longer no-decompression times, reduced gas consumption, and the encounter of unparalleled life forms.
What is a rebreather?
The main difference between a rebreather and an open-circuit unit is that the former reuses some or all of the gas you exhale. There are two basic types of rebreathers: closed-circuit rebreathers (CCR) and semi-closed-circuit rebreathers (SCR).
To introduce divers to recreational rebreather diving within the no-decompression limits, PADI Rebreather and Advanced Rebreather Diver courses use Type R units: Type R rebreathers are electronically controlled, provide a backup of all major systems and simplify training and use.
All rebreathers used in PADI courses must have been third-party tested, and their manufacturers must ensure that these units meet a very comprehensive list of requirements.
Since each model of rebreather is different from the others, you will need to qualify for the use of each one. However, once you’ve qualified, you don’t have to repeat the entire course to become certified for a different model of Type R rebreather: the PADI Rebreather Qualifier program focuses on the theoretical and practical knowledge needed to use a different model of Type R rebreather.
PADI Rebreather Diver
In this entry-level rebreather program you will learn how to use Type R rebreathers up to a maximum depth of 18 meters/60 feet and within the no-decompression limits.
Prerequisites:
- Hold PADI Open Water Diver and PADI Enriched Air Diver certifications (or qualifying certifications issued by another recognized organization);
- Have logged 25 dives;
- Be at least 18 years old.
PADI Advanced Rebreather Diver
This course extends the basic knowledge already learned and provides training up to a maximum depth of 30 meters (40 meters if you are PADI Deep Diver certified), including carrying a “bailout” tank.
Prerequisites:
- Possess PADI Open Water Diver and PADI Rebreather Diver certifications (or qualifying certifications issued by another recognized organization) for the Type R rebreather used in the course;
- Have logged 30 dives;
- Be at least 18 years old;
- Hold PADI Advanced Open Water Diver certification (prior to PADI Advanced Rebreather Diver certification).
