I am getting my gear configured and ready to take a intro to cavern class by the end of the summer. The reason I am waiting this long is to really become used to my new BP/W set-up and hose configuration, from changing over from a jacket-style BC. My question to you certified cavern, cave divers, and instructors out there is about doing my intro to cavern class with a single tank set-up. Will I be required to have an H-valve on my single tank in order to take the class or will a standard K-valve be ok for the intro class?
