All right,
I swear i am not trying to pick a fight...BUT
Well, first it sounds like i wouldn't shop there about the EAN Decals. Personally if they said I had to buy them I would ask how they could fill them without me having those labels on. I mean some newbie, in the shop could steel them and get ox tox
Or i'd say i don't want them and you can have your nitrox back!
Seriously though...kinda, how much should they charge you if they don't have a per cu ft fill plan?
I don't know about the shop you have, but here:
figure a pair of oms LP 119's, double dins, iso valve, bands, boots, and the air in them, maybe they weigh 100 lbs, just guessing.
we have to lift them up, bring them over to get analyzed, put the FO2 and PSI into the computer, take the doubles to the cascade, bring them over to the fill station to top them off, analyze them, put them some where till you come to pick them up, bring it over for you to analyze it yourself, and then carry them out for you. so, because you are just having them "topped off" the shop shouldn't charge the price of to EAN fills. Again, i am not trying to piss you off, just tell you what your shop might have to go through to fill tanks.
did you tell them when you needed the pony tank by?
