I would spend the next 3 or 4 years working towards AN/DP+rec trimix (or whatever they call it), NAUI T1, GUE T1, or one of the other entry level, ~160ft, normoxic OC trimix courses. When you have 75-100 dives in the 130-170ft range on OC mix with deco then you'll be in a better position to decide what's next. That would be a reasonable point to switch to CCR if you still aspire to 200+ft dives.
Wrecks like this one would be much better if divers were not obsessed with looting.
It doesn’t get thrown out and it’s not junk to the person that finds it. It’s a memento of a great dive and a wonderful day out. I’d love to find a Meg tooth, I’d make a little base for it and treasure it. The items you’re talking about will not be there for others to see but will be buried in tons of rotting steel, If there’s anything of value in a wreck the commercial operators move in and make a giant scrap yard of it,All of this junk ends up on some idiot's shelf where nobody ever looks at it and after 20 years it gets thrown out.
