NAUI Cave Level II  
 NAUI  cave level I is quite an extensive class, and allows you to complete many pleasurable and interesting dives, in fact Cave Level I may be all you need to perform the dives that you want.     However; for those who wish to go further and increase their penetration range or level of dive complexity then a NAUI cave level II can provide the additional training you needed to expand your explorations as safely as possible. 

Class prerequisites:
Cave II is a class for those who are already comfortably executing cave dives. 
  • Minimum Age 18
  • NAUI Cave I level or equivalent
  • NAUI Decompression techniques or equivalent.
  • A minimum of 100 logged dives
  • A minimum of 20 logged cave dives since level I graduation

In general I will chat with each individual regarding their diving experience and motivation for the class.  Cave II is an advanced class and it is expected that all basic cave diving skills are already mastered by the prospective student.  If possible I will try to schedule a review dive or obtain a recommendation from previous instructor(s).  

Skills Required to Complete the Class

  • All Cave Level I skills
  • Knowledge of and execution of a cavern survey
  • Five cave dives using at least one stage cylinder completed to the satisfaction of the instructor.
  • Ability to plan and execute cave II level dives including decompression, gas management and complex navigation.
  • Perform the required skills maintaining controlled buoyancy and trim using two stage cylinders.
    1. Helicopter turns
    2. Back up at lest 10 feet
    3. Drop and recover stages
    4. Shut down and switch within 15 seconds
    5. Rescue of a diver simulating Oxygen Seizure.
    6. Survey a cavern and create a map.
    7. Gas Sharing exit 200 ft
    8. Gas Sharing exit in blackout conditions 200ft.
    9. Cave navigation with multiple guidelines and the use of maps for dive planning.
    10. record data from dives to use for future planning.

The class has several lectures and a minimum of 5 dives,  This can be accomplished in a 6 day class, or it can be  broken down into weekend chunks over a period of time.    The class starts out with classroom and skill review,  this is then followed by progressively more complex cave dives which will incorporate the necessary cave diving survival skills.    

It should be noted that participation in the class does not guarantee certification.   Should you not get certified at the end of the class I will provide you with a guide as to which areas require more practice,  and I will happy to assist you with working on this.  In most cases it is not necessary to repeat the class, simply work on the skills that are outlined and then demonstrate you have mastered them.
