This quote from the Luxfer site, and I could not agree more.
This whole Visual Inspection/O2 Clean thing is IMO a LOT of BS that the LDS has created in many ways. Certainly we want things to be safe... BUT, I just researched this a LOT as I was looking at used tanks.
I can take my tank to the Local Hydro place myself. They do the Hydro at 5000psi (3000psi tank), clean the tank, and do a visual inspection. That costs about $15.00, and that is the majority of the work. But THEN the LDS will NOT fill the tank until it has been Visually inspected by a LDS.. HELLO? It just passed a 5000psi Hydro test, and a Vis.. IT IS READY to be filled. So what does our LDS charge for a Vis? $20!!! WHAT? That is MORE than the Hydro place charges for the complete Hydro AND a Visual inspection.
It get's worst. If you puchase a tank from ScubaToys, it will come with a Vis inspection sticker from the Dive shop, is new, and ready to be filled. However the LDS won't honor the vis even thought it's obvious that the tank is new, and ready for a fill. Why? IMO it is punishment for not putting up the $200 they want for an AL80, and purchasing online.
IMO this is a throw back from the days when LDS's price fixed everything, and this is one of the few area's where they are in control. My buddy purchased ALL of his dive gear from our LDS at foolish prices. He then came to them with used tanks that needed O2 clean and a vis (he hydro'd them outside of the LDS). They initally refused to even fill them with air, and were wanting $100 to O2 clean two tanks. Worst, the only guy in the shop that does O2 cleans is heading to Indonesia for three weeks so they told him it would be at least a MONTH before he'd get a fill. At my suggestion he put his foot down, and basically demanded an air fill. They agreed, only after this very valuable and profitable customer complained.
IMO this is all foolish.
