The E8's have been in the shops around here for a little while now, it helps that the tanks are made at a factory only 70 miles from here.
I wouldn't understand why a diveshop wouldn't fill them. I know that they might have an issue filling them all the way up to 130cuft. level, but they should at least fill them to the 104 point (2640psi) that they have been certified to for years now. It's basically the same tank put through a higher pressure test to get the higher rating.
The whole DIR / GUE thing is starting to gain momentum around here. We have a club, called D.E.E.P. midwest that uses all DIR gasses and gear setups. We have members from 4 states that come to participate in wreck divig projects, and some of them are also involved in some cave diving stuff as well. A few freinds of mine just got back form diving the Gunilda and the Judge Hart, both up in Canada. I was invited but couldn't come up with the cash, and I have been selling off all of my tech stuff to pursue freediving more seriously.
There are still a few die hards around who bad mouth it every chance they get, but I stopped diving with them a while ago because they kept running out of gas on deep dives- it's not DIR to know what your SAC rate is.:duh These are also the guys getting bent because they can't seem to follow a table or read their computers through the fog of narcosis.:head
I have had a chance to dive with GUE trained divers, that I had never met before, and had wonderful dives. All of our gear, gasses, deco tables, and attitudes matched up at the dock. On the bottom, even with less than 3' of vis and 3- degree temps, we worked like a team who had been diving together for years. There really is some beauty to the simplicity of the whole system.
A buddy of mine is bringing Andrew and Michael back out this fall for another DIR-F class. The one held last spring was a sell out and there are already people signed up for the next one.
We even have a mulit-county dive rescue team forming to do mixed gas, DIR style, recovery work that the other teams can't handle safely.
