PADI Deep Diver
The PADI Deep Diver course prepares you to safely explore deeper dive sites while improving your awareness, planning, and control underwater. Learn how depth affects your body, your equipment, and your decision-making — while building the confidence to dive safely up to 40 meters.
What you need
Course structure
Certification
Depth changes everything underwater.
Deep diving requires more than simply descending further. As depth increases, gas consumption changes, no-decompression limits become shorter, and awareness becomes more important.
This course focuses on safe deep diving practices, proper planning, and maintaining control underwater while building experience step by step in deeper environments.
Learn how depth affects both the dive and the diver.
The course combines theory, controlled skill development, and supervised deep dives. You’ll learn how to manage gas supply, recognize the effects of depth, and safely plan dives within deeper no-decompression limits.
How the course works
-
01
Theory and dive planning
~2–3 hoursLearn about nitrogen narcosis, gas management, no-decompression limits, emergency procedures, and how to safely plan deep dives.
-
02
Skill development
Controlled practicePractice descent techniques, buoyancy control at depth, monitoring gas supply, time awareness, and backup safety procedures.
-
03
Open water deep dives
Progressive depth divesComplete a series of dives at increasing depths while applying dive planning, practicing safe ascent procedures, and building confidence underwater step by step.
This course is perfect if…
- You want to safely explore deeper dive sites and environments
- You are interested in deep reefs, walls, and deeper wrecks
- You want to improve your awareness and planning underwater
- You want structured training before diving beyond recreational depth limits
What you will gain
Safe deep diving skills
Learn how to safely plan and conduct dives up to 40 meters while managing depth-related risks properly.
Improved awareness underwater
Understand how depth affects your body, gas supply, decision-making, and no-decompression limits.
Better buoyancy and control
Deep diving improves precision underwater, especially during descents, ascents, and safety procedures.
Access to deeper dive sites
Explore deeper reefs, walls, wrecks, and underwater environments within recreational depth limits.
As depth increases, gas consumption rises, no-decompression limits become shorter, and the effects of pressure become more noticeable. Deep diving requires additional planning, awareness, and control underwater.
Nitrogen narcosis is an effect caused by increased pressure at depth, which can affect awareness and decision-making. During the course, you’ll learn how to recognize and safely manage it.
After completing the course, you’ll be certified to dive up to 40 meters / 130 feet within recreational diving limits and your level of training.
