Altitude Diving Specialty

If you want to dive cool inland lakes...you need this course

Any time you’re diving at 300 to 3000 metres/1000 to 10,000 feet above sea level, you're altitude diving. If you want to explore the hidden world of a mountain lake, the PADI Altitude Diver Specialty course is for you.

Dive more challenging dive sites while you satisfy your curiosity for “I wonder what’s down there?” The fun part about altitude diving is that you can explore places many people have never seen.

The course is made up of two open water dives and a classroom session.  Dive planning is very different when conducting an altitude dive, you have to use different tables with altitude correction factors before you can know how long and how deep you can dive.

Some of the  things that you will be able to do after completing this course:

  • Describe the importance of the “pressure ratio” that dive tables and computers use to help divers avoid decompression sickness.
  • Explain how diving at altitude affects this pressure ratio.
  • Calculate the approximate atmospheric pressure for various altitudes up to 10,000 feet. 
  • Explain how far any decompression theory can be relied on to keep the risk of decompression sickness within an acceptable minimum, and why. 
  • Describe how the lack of empirical data (documented hyperbaric test dives) on altitude diving affects altitude diving, flying after diving and driving to altitude recommendations. 
  • Compare and contrast the theoretical and practical differences between altitude diving, flying after diving, and driving to altitude after diving. 
  • List the current recommendations for flying or driving to altitude after diving.

These are just a few of the academic topics that you'll learn during the altitude diving course.

Prerequisites are Open Water Diver AND some cold water diving experience. 

Course Cost is $125 and includes all materials, the class time, and the open water dives.  By this point in a divers training it is important that a student begins to obtain their own equipment (rentals are available but having your own gear is preferred).  


The Learning Materials Included

HiTek Scuba has put together the learning materials required to complete this program. The materials are specifically designed for the Pacific Northwest and to give you everything you need to safely learn to dive at altitude, specially written for our own backyard.
