Advanced Sidemount Cave Diver course

There is sidemount…and then there is advanced sidemount.

  • Basic Sidemount Diver is a course you would take either before or in conjunction with your beginning Cave Diver training. It’s goal is to train you to use sidemount as a primary gear configuration, much as you would backmounted doubles. Other than for dealing with possible entanglement, it does not get into cylinder removal or passing through extreme restrictions that might require dropping one or both cylinders.
  • Advanced Sidemount Cave Diver is a course that goes well beyond this. It deals specifically with passing through the tightest of restrictions — restrictions that, invariably, require shedding one or both bottles.

This is an extremely advanced form of cave diving and, as such, entails considerable potential risk. Managing this risk is a big part of what we cover in this course.


  • Be at least 18 years old
  • Have 50 or more logged dives
  • Be certified to the Full Cave Diver level or equivalent
  • Possess Nitrox Diver certification

As you will be diving sidemount during this course, you need to be able to document prior training or experience in its use. This includes several sidemount cave dives.
