To enroll in a Master Freediver course you must be at least 18 years old and have a Advanced Freediver certification (or a qualifying certification from another freediver organization). You also need to have Emergency First Response Primary and Secondary Care (CPR and First Aid) training within the past 24 months. You can complete this training during the Rescue Diver course. Your instructor may also offer the Emergency Oxygen Provider specialty diver course at the same time.
The Master Freediver course consists of three main phases:
- Knowledge development about nutrition, relaxation and advanced breathing techniques. You'll study independently using the Freediver eLearning (or your instructor may conduct class sessions if not available in your language). You'll also complete independent research as part of the Master Freediver Assignment.
- Confined water session to improve static and dynamic apnea attempts, including a no fins dynamic apnea. Goal - static apnea of 3 minutes, 30 seconds and dynamic apnea of 70 metres/230 feet.
- Open water sessions to practice mouthfill equalization and perform warm-up and workup dives for free immersion and constant weight freediving. Goal - constant weight freedive of 32 metres/105 feet.
You need to have a freediving mask, snorkel, bifins, wetsuit and weight belt. Your instructor may allow you to use monofins. You'll also need a surface signaling device and a freediving computer (or depth gauge and timer).
