I am looking to buy my first set of equipment A.S.A.P. Before I head out I want to be armed with some basic knowlegde but I can't seem to find a single source on-line for the basics. For example, where can I find info about the differences between regulators (piston, diaphram...), wet suits (full, farmer john, wet dry...), BCs (jacket, plate, wings...) I think you get the idea. I know this place is great for getting folks' opinions on specific gear/brands, but I want some sort of equipment primer that will let me ask educated question and make sure what a dive center is selling me is actually what I want. www.scubadiving.com has random info about equipment basics if you go digging. Can someone please point me to a more consolidated source? Thanks!
