Deep Diver
Down to 40 meters. Safe, prepared, fascinated.
The depths have a unique allure—different colors, a different kind of silence, and different creatures. With the Deep Diver Specialty course, you’ll extend your diving depth to up to 40 meters and learn what sets deep diving apart from other dives: physiologically, technically, and psychologically. You’ll head into
the depths—and know what matters.

WHAT YOU'LL BE ABLE TO DO AFTER THE COURSE
The Deep Diver course combines theory and practice into a compact, intensive program. Upon completion, you will be able to:
To understand and apply the interrelationships between physics, medicine, and psychology in deep diving.
To have a solid grasp of the fundamentals of decompression theory and to plan deep dives in accordance with the rules.
To be familiar with the technical requirements for deep-diving equipment—especially in cold waters.
Assessing your dive partner underwater, responding to their needs, and diving safely together.
The focus isn't just on technical skills: The course also promotes an awareness of the underwater ecosystem and how you can share your newly acquired knowledge as an experienced diver.
Theory (2 class periods)
The Physics of Deep Diving: Pressure Changes, Gas Solubility, and Changes in Light and Color at Depth
Medical Considerations: Nitrous Oxide Anesthesia, Oxygen Toxicity, Decompression Sickness – Recognition and Prevention
Psychological factors: depth-induced dizziness, overestimation, stress reactions
Fundamentals of decompression theory: no-stop times, safety stops, emergency procedures
Technical requirements for deep-diving equipment, especially in cold waters
Planning and debriefing of deep dives
Assessing and assisting your dive buddy at depth
Practical Training (2 dives)
The two practical dives will take you down to a depth of 40 meters in a controlled manner. You’ll put what you’ve learned into practice right away: dive planning, buddy check, buoyancy control at depth, and a safe ascent with a safety stop. The instructor will be with you every step of the way.
