Intro to Cave traning limits a diver to a single tank w/H valve installed. Other than Ginnie and in Fla, which LDSs offer Nitrox tank rentals with an H valve installed?
Thanks

but the Intro to cave training specifies a single tank with H valve.
From NACD Web Site:?? What agency is this?
Thanks. This is exactly the information I was looking for.I believe every agency offers a certification that specifies what amounts to "intro in doubles." Some call it Basic instead of Intro. Some have it expire and revert to Intro after 18 months or a year.
Doubles are easier to rent and because you should, barring an emergency, exit with 2/3 of your gas remaining instead of only 1/3 in a single tank, give you a wider safety margin for any big screw ups.
Some people are uncomfortable using them if they have never used them before, but I personally found doubles very easy to get used to. It's not a dumb idea to try and dive in them before the class.
