TecRec Courses

Discover the balance and efficiency of sidemount scuba diving with your PADI dive instructor. Many divers find sidemount tanks are more comfortable and easier to put on in the water. Sidemount diving is also beneficial for divers who want improved balance and prolonged dives.

Take technical scuba diving training DSAT Discover Tec lets you try technical diving equipment and procedures.

What You'll Learn

You learn about technical diving and get to try it out. Plus, Discover Tec experiences can also credit towards the Tec 40 course.

The Scuba Gear You'll Use

You will need your basic scuba gear and you will try technical scuba diving equipment.

The PADI Tec 40 course is where you transition from recreational diving to technical diving. It's a natural progression from Tec Basics, or it can be your first tec diver course. It is the bridge between no-stop diving and technical decompression diving. You will gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet and use up to 50 per cent oxygen as a decompression gas.

The Tec 40 course consists of seven knowledge development sections, four practical application sessions and four training dives. You'll learn about:

• Technical diving risks and responsibilities
• Technical diving equipment, dive equipment configuration, and use
• Team diving and communication
• Decompression and gas planning using dive planning software
• Team diving techniques and emergency procedures to deal with free flows and out-of-gas situations
• Thinking Like a Technical Diver
• Handling Underwater Problem

The PADI Tec 45 course extends your depth limit to 45 metres/150 feet. You will learn to plan and execute single and repetitive decompression dives using a single decompression cylinder with up to 100 percent oxygen. You will use double cylinders, which can be either back mount or sidemount diving configuration. Tec 45 is a prerequisite to Tec 50.

Your Tec 45 training consists of seven knowledge development sections, four practical application sessions and four open water dives. Building on what you learned in the Tec 40 course, you will focus on additional techniques, procedures, and emergency skills. You will learn more advanced decompression, gas planning, decompression models, and fine-tune your thinking like a technical diver. This is a course where you rise to the challenge and commit to becoming a technical diver.

The Tec Gas Blender course includes three practical application sessions, but no dives. During independent study and instructor-led review, you learn:

• About the advantages and disadvantages of different blending methodologies.
• To blend enriched air and trimix blends to within one percent of the target mix.
• About the potential hazards related to handling oxygen, and how to manage those risks.
• To demonstrate the steps for oxygen cleaning equipment, along with the requirements for oxygen service.
