I`m bummed ... one of my dive buddies/coworkers is heading out to Australia til Sept for work. Lucky SOB. He`s got tons of exp ... as a dive master/guide on a liveaboard, but programming computers is dull but pays the scuba bills. I thought I didn`t use that much air (SCR btwn 18-19 psi/min for AL-80, wicked current cranks it up to 30), but he uses less - but I`m getting there. I guess it comes w/ the experience. I`m hoping to get divemaster cert by the end of the summer. It`ll be a nice sideline gig for the weekend, but more so for self fulfilment - kinda like a master`s degree. PhD (aka instructor cert) perhaps? Eh ... baby steps. See how dive master is first.
