Well any questions you have I'd be happy to answer... as for "certification"... IMO... all it's good for is giving you the ability to fill tanks when you need them... the REAL education comes from diving yourself, and diving with masters when you can... I lost interest in scuba once I got past OW2... about that time some people too close to me got hurt doing "standard" profile dives... scuba has a level of uncertainty to it... each person is affected differently at extreme depth... and unless you're a navy diver with a deco tank waiting on you... diving at depths greater than 100' on scuba is (albeit a small probability) like playing russian roullete...
Had several guys I know take a "hit" at depth and get paralyzed.... EXPERIENCED deep divers. One went down to pull out a stuck anchor and when he went to yank the thing out, a nitrogen bubble formed in his spine and that was it.
I can freedive just as deep as any scuba and not have to worry about that chit. Less gear, less drag, and less headaches... when scuba friends have to get in the boat to do their deco's... I just keep diving
... I've dove with kooks that had certs out the wazoo... book smarts, however, don't translate well at depth when chit hits the fan haha
