What are you trying to do get him in trouble right off the bat (LOL). The dive shops around here can only do or will only do 3200 to 3300 psi in the Vancouver area . The place that used to do mine to 4500 vanished over night & ran with everybodys pre paid fill cards .I get mine filled in troutdale Ore. Sorry but I don't have a compressor as of yet or I would do it for you . There's a place in S.W. Portland that can do it from what I hear but haven't had time to check it out . P.M. me & I'll give you my number C/C might still have it. If you need some help I'll try, would like to meet up with you if ya have enough time . Hope the weather is good Darell P.S. forgot to add I'm 15 min away (Ridgefield)
