i have been scuba diving recreationally for about 4 years now
and i just recently got back from a trip to catalina island and while i was there someone was telling me about free diving and how you can take someone with little experience and teach them to hold their breath for 4 minutes!! no problem!!
im into extreme skiing, dirt bike riding and scuba diving and this free diving subject intrigues me deeply
so whats the first thing i need to read to get me started and on my way
