I agree that being comfortable in water is a key to being a good scuba diver. I just don't see how free diving makes you more comfortable in water than scuba. I grew up free diving in Puerto Rico and back then, as a kid, I could free dive to 30 ft, while some of my buddies could dive to 60. Not that I couldn't dive to 60, I felt more comfortable at about 30. In scuba, I feel equally comfortable at any depth as I did at 30' free diving as a kid. I have done some free diving to about 40' in Hawaii, and again, I felt as comfortable free diving then as I do now in scuba. I only had 1 dive at that time, a resort dive I did in St. Lucia 6 months before.
Now, what I will agree is that people who are accustomed to snorkeling or free diving will, perhaps, not have as much comfort issues straping on scuba as someone that has not ever snorkeled or free dived before; the mask can be somewhat intimidating, and breathing in and out the mouth is an acquired skill.
MIKE FERRARA:
It also doesn't do anything to teach breath control (even when handling a problem) because you're not breathing.
I agree with Mike on this. I believe Mike is referring to the breath control at depth that only comes from being on scuba, and the buoyancy control that comes as an inevitable result of breath control at depth. This cannot be done while freediving.
QUIMBY:
I will never believe someone who is a accomplished freediver is not in better control of his body in the water than someone who hasnt.
Again, speaking in my experience, I do not notice the difference. I have friends who have not free dived a day in their lives and are as in control of their bodies as I am, and I grew up free diving.
QUIMBY:
They are more tuned to the demands of their lungs, and more ready to deal with any situation with or without equipment.
I fail to see how controlling the lungs at the surface implies control of the demands of their lungs at depth. It doesn't mean I disagree, it means I just fail to see the connection.
