Individuals looking to acclimate themselves to freediving methods and safety protocols can receive breath-holding know-how with Nautilus’ F.I.I. Intro to Freedive and Safety Course, a full-day class that gives diving neophytes a firm foundation in tankless diving and the basic knowledge required for future freediving education.
