    I nearly spat up coffee - that was so funny. I did my original course with Bill High - he was as dry as Mark.

    Me, too. Both classes were the same as I described above.

    It isn’t a matter of blame, it’s a reminder to the owner of the tank to insure that an expensive mistake is not being made.

    I know the expertise in performing a VIS varies widely from shop to shop in my area. If this were to happen to me, I would take it to my hydro shop unless I could absolutely confirm the issue myself, which isn’t likely.

    No one has done anything wrong, and if the OP lets the shop condemn the tank, it doesn't bother me, it’s no money out of my pocket

    I think you are really splitting hairs here. My point was that a dive shop does not have the authority to condemn or destroy a customer's tank. You apparently agree with that. Of course if you give them permission they can do whatever you gave them permission to do.

    No I am not splitting hairs. The use of term "legal" / "illegal" has a very specific meaning. You used it incorrectly. Because of that it diminishes what follows.

    Definitely looks like cracks in the pictures that I received. On the higher magnification...to me...it looks like another crack is forming (above the obvious ones).

    @Barnaby'sDad well I'll be damned, that's a first for me! I called my buddy that does all of my hydro's and he says he's only ever seen 2 steel tanks with actual cracks in the threads. Both were spun Asahi's. He hydro's about 200 bottles/day and has been doing it for about 20 years...
