Taking the lead from sirielle, I have Photoshopped in comments indicating what you're looking at (since dive gear can look pretty mysterious to a non-diver) and explaining what's what for anyone who is interested. The only thing I couldn't photograph were the air tanks, which we returned yesterday. But that's one of the more boring items anyway.
Oh, and if you see strange numbers painted on the stuff...it's rental equipment! The wetsuits, BCD, gloves, hood, and regulator are all rental gear.
