Altitude Diver

Altitude diving introduces divers to the unique considerations of diving at elevation, where pressure changes and environmental factors affect planning and execution. This course focuses on understanding how altitude impacts dive profiles, decompression theory, and surface intervals when diving above sea level.

You’ll learn how to properly plan dives in mountain lakes and high-altitude quarries, adjust dive tables or computers, and recognize the differences between sea-level and altitude environments. The course emphasizes awareness, preparation, and accurate dive planning to ensure safe and enjoyable dives at elevation.

The Fun Part

Altitude diving opens the door to some of the most scenic and less-crowded dive sites available. From clear mountain lakes to high-elevation quarries, you’ll experience a different side of diving that many never explore — all while sharpening your planning skills and expanding where you can safely dive.

What You Learn

• How altitude affects pressure and dive planning
