You CAN even do your OW course to be combined with a drysuit course, so you don't ever have to dive cold and wet, even on your OW checkout dives. I think a lot of OW courses in the UK are actually taught that way by default (OW and Drysuit combined into one course).
Thank you; I did not know that! I like that idea. I assumed, incorrectly, I would need to do the OW as a prerequisite to any other course; a weird college mindset that I didn't even think to question. I expected the water in CA to be warmer; and it is warmer "in season". When I looked at the current temps I got a bit of a chill running up my spine I have to admit the aqualung 7mm looks quite comfy and is supposed to be quite good -- I was impressed when I compared 7mm suits to 7mm suits. Outofofficebrb is a CA diver in S.F. and it is much colder there. From her profile pic she looks petite (and quite pretty); she is diving in colder water and doesn't have as much "natural" insulation as I hehehe. Yeesh, tough decision. While looking I was thinking I would still need a thinner suit because I want to dive where it is warmer too. I also have had my eye on dry suits, so that would make 3 suits and they aren't cheap. I'm wondering now if I should narrow it down to 2 and take the dry suit course with my OW -- so many choices
