TEC DIVING COURSES
PADI Tec Diving
Technical Diving allows you to go beyond the limits of recreational “no-stop” diving. With technical (tec) training, you can plan longer dives at shallower depths or explore more advanced depths and challenging environments. It’s the next step for divers who want to expand their skills, knowledge, and experience the underwater world in ways few ever do.
Benefits of Technical Diving:
Increased Range: Explore depths beyond 40 meters / 130 feet.
Expanded Environments: Dive in caves, shipwrecks, and other unique or overhead environments.
Advanced Skills: Learn to use specialized gas mixtures and decompression techniques.
Specialized Equipment: Gain proficiency with advanced gear configurations designed for safety and performance.

PADI Tec 40 Course
3 DAYS
The PADI Tec 40 Course is your first step into the world of technical diving , the bridge between recreational diving and full technical decompression diving. It’s designed for divers who want to go beyond recreational limits and start exploring the methods, equipment, and mindset of tec diving.
You’ll complete:
7 knowledge development sections
4 practical application sessions
4 open water training dives
During the course, you’ll build on your existing diving experience, learning to plan and conduct limited decompression dives to a maximum depth of 40 meters / 130 feet. Whether you’re moving up from Tec Basics or starting your first Tec Certification, the Tec 40 course gives you the skills, confidence, and understanding to continue your journey into deeper and more advanced diving.
What you will learn:
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 Problems
Equipment to be used:
You'll use full technical dive equipment (double back mounted tanks or technical sidemount configuration) plus one decompression cylinders.
Gases to be used:
You'll dive Air or EANx, including up to 50 percent enriched air for decompression. If you’re taking the Tec 40 Trimix Diver course you’ll also use trimix.
PADI Tec 45 Course
2 DAYS
This is a course where you rise to the challenge and commit to becoming a technical diver. The PADI Tec 45 course extends your depth limit to 45 meters/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’ll complete:
3 knowledge development sections
3 practical application sessions
4 open water training dives
There is also an option for divers to earn a Tec 45 Trimix Diver certification.
What you will learn:
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. Tec 45 Trimix students will also learn about diving trimix.
Equipment to be used:
You'll use full technical dive equipment (double back mounted tanks or technical sidemount configuration) plus one decompression cylinders.
Gases to be used:
You'll dive Air or EANx, including up to 50 percent enriched air for decompression. If you’re taking the Tec 40 Trimix Diver course you’ll also use trimix.
PADI Tec 50 Course
2 DAYS
As a Tec 50 diver, you’ll have the knowledge and skills to make extended range dives to a maximum of 50 meters/165 feet. You’ll know how to make dives with multiple decompression stops using two decompression gases. It’s not easy to reach this level. Earning your Tec 50 certification opens the door to deeper diving expeditions.
You’ll complete:
3 knowledge development sections
2 practical application sessions
4 open water training dives
There is also an option for divers to earn a Tec 50 Trimix Diver certification.
What you will learn:
The Tec 50 course consists of five knowledge development sections, four practical application sessions and four training dives. The primary focus of this course is learning advanced dive equipment options, techniques and procedures using two deco cylinders, and how to plan more complex dives. You also learn more how to handle emergencies, support diving considerations, and sharpen your thinking as a technical diver. Tec 50 Trimix students also learn about dive planning and diving with Trimix.
Equipment to be used:
You'll use full technical dive equipment and may use technical sidemount configuration, plus two decompression cylinders.
Gases to be used:
You will use Air, Nitrox and 100% Oxygen during your decompression dives.

Why Tec Diving?
Here are the main reasons divers choose to get into technical diving:
Explore deeper sites – Tec diving allows you to go beyond the 40-meter/130-foot recreational limit to visit deeper reefs, walls, and wrecks few others ever see.
Access more challenging environments – It opens the door to overhead environments like caves, mines, and deep wreck penetrations where standard recreational limits don’t apply.
Extended bottom time – By using different gas mixes and planned decompression, you can stay longer at depth to explore or complete complex tasks safely.
Skill development – Tec diving pushes your planning, buoyancy control, gas management, and problem-solving skills to a higher level, making you a more confident and capable diver overall.
Adventure and personal challenge – Many divers are drawn to tec diving for the mental and physical challenge—it’s a way to test limits responsibly and achieve new goals underwater.
Scientific or professional goals – Some divers pursue tec training to support underwater research, photography, archaeology, or conservation projects that require deeper or longer dives.

Frequently Asked Questions
about the PADI Tec Diving Courses
-
YES! We will dedicate one instructor exclusive to your course and the maximum size of the group is 2 people.
-
Trimix is a breathing gas used in technical diving that contains 3 gases:
Oxygen (O₂) – supports life and metabolism.
Nitrogen (N₂) – helps balance the mix but can cause narcosis at depth.
Helium (He) – replaces part of the nitrogen to reduce narcosis and make deep diving safer.
-
Doubles involve carrying two tanks on your back, while sidemount involves carrying one or two tanks attached to your sides.
Doubles are often considered more comfortable for long, open-water technical dives and are simpler to start with, offering more gas volume with less complexity in gas management.
Sidemount provides greater flexibility, better streamlined trim, easier transport, and easier access to valves, making it ideal for confined environments like caves, and for divers with certain physical limitations.
