wait, the tanks were free? where'd you find them, craigslist dumpster diving section?
No, there was a sign on the side of the road that said "Free Diving gear". I stopped and looked and took it all. Two regulators, old but still functional and good for parts. A BCD but not the kind I'll use. A wetsuit, small ladies. Lots of assorted small stuff like a beacon light, keepers, snap links, two masks and a flashlight. Five steel 72's. Three of them were still within the Hydro test date although all of them need VIZ's. Those three were put aside while I concentrated on the two others.
One looked good but was out of Hydro date. That one passed the Hydro test but failed the Viz. I'll tumble it and get it done again. (But someplace else!) This is the one that started me wondering about the lack of consistency of their procedures. The last tank looked pretty rough. I was planning on refinishing it as a project if it passed.
After I checked all my "free stuff" over, I ended up with a pile of small items and hardware that are all serviceable, a couple of old regulators that actually have good IP's, a BCD that I'll never use and five steel 72's, at least three of which are perfectly are perfectly usable. All for free.
Now, I am absolutely positive that someone such as yourself would never stoop to such a disgraceful low and shame yourself by taking and using free SCUBA tanks (Gasp! The horror!) but I have no such silly or stupid hangups so I'll use these tanks.
P.S. If you see any signs for free Scuba gear, point them out to me.
