Just saw another post in another area of SB, person talking about tanks and getting "cave fills". I did not know what a cave fill was until I got my first one in Florida ( not in cave country ) a few years ago. Took my tanks to a shop, and just asked for a fill. Guy chatted to me and I told him I was vacationing and was going to be doing my cavern course. When he was done he said he had given me a little extra, a cave fill. Now I am used to getting a few hundred pounds extra, cool down and all that, but the fill was at 4000lbs, I might have come close to frying an egg on the tank it was so hot. I have to be honest, ( and this has happened again on my double 130's a 4000lb fill) it kind of gives me the heebee geebee's tossing a set of tanks with 4000lbs in them into my truck and driving with them. I know the burst disk should be what goes if the pressure gets to high, and I have been around for one of them going, but still.
Ironically I have never gotten a "cave fill" in cave country.
So what are the thoughts of the experienced folks, ( I am new to cave diving), is my concern unfounded, or am I making a good choice when I say, 3600-3700 in my 130's is plenty?
My experience filling in cave country is that I get the 3600-3700 at the most. My understanding as well is the high pressure can do damage to a first stage.
