Questions about this course?


The Zuba Open Water course is an entry level course designed to teach non-certified Zuba (Z-Float Underwater Breathing Apparatus) divers to be safe and comfortable while enjoying the wonders of our oceans, lakes, rivers, pools and other waters.

This course is structured to prepare adults, 16 years and older, for Zuba diving without supervision of a dive master or instructor.  The course certifies the student in the use of proper equipment and proper Zuba diving techniques.  The course incorporates Zuba diving theory, knowledge and equipment configuration with precise Zuba diving skills and emergency procedures.  This course not only teaches you how to use the equipment, but it teaches you how to be a safe and environmentally aware Zuba diver.

Upon completion of the Zuba Open Water certification, a diver can use an independent Z- Float system, can purchase or rent Zuba equipment, and receive the necessary air fills from any dive shop.

The Zuba Open Water course is normally conducted over a 2 day period, and cumulatively involves a minimum of 10 hours of instruction including academics, confined water, and open water dives to a maximum depth of 20’/6m using air as a breathing gas.

Course Upgrades

Your Zuba equipment and certification are consistent and upgradable to become a fully certified Scuba Recreational 1 or Open Water diver.

Course Information

The Zuba Open Water course is designed to provide a introduction to Zuba equipment configuration, basic diving physics and physiology, situational awareness and understanding the aquatic environment.  The in-water skills will first be conducted in a confined water environment prior to entering the open water.  These skills will include, but not be limited to, snorkeling techniques, buoyancy, trim, propulsion, basic 6, and air sharing.

Course requirements include two hours of academic review and 2 hours of confined water training, a minimum of 1 skin dive and 2 open water dives, 1 of which will be an orientation dive and 1 will be a skills dive.
