hey all, came across a guy selling some used Al 80's on Craigslist. after a couple email exchanges, decided the guy was pretty shady, so am considering firing off a nasty reply. am i being too harsh?
(see email exchange and hypothetical nasty reply below).

Saw your ad on craigslist for the aluminum tanks. I was curious about some other info..do you know how old the tanks are? And when they had their last hydro, visual, and/or eddy current tests? also would be great if you happen to know what alloy aluminum they're made out of (particularly if they're Alum 6351). Thanks,

I've had them for 10 years. They have been great tanks for me. I've used them in my own hull cleaning business, while I was going to College of Oceaneering, and after as a commercial diver. during that time I kept them well mantained. I'm sure both need hydro and visual. I'm no longer diving, so my change in career paths can be your opportunity. Call to come by to check them out if interested. phone number was on the add.

I guess what i'm after really is all that good info stamped on the neck of the tanks. "DOT-3AL...etc, etc....hydro test dates, etc". That stuff will tell me pretty much everything I need to know. if you could pass that info on sometime, great, otherwise i'll pass. thanks,

Hi Adam,
The blue tank with the tank boot has the following:
CFC/DOT - 3AL3000-580
It had the hydro and visual in 08-01
The blue tank without the boot has the following:
3AL DOT-E6498-3000
P223111 USD
It had the hydro and visual in 08-01
hope this helps,



i'm glad i know to ask the right questions, and i hope you don't end up unloading those old tanks on some poor, unsuspecting newbie.

i suspected these were old tanks from the start, which is why i asked for their age. your answer, that you'd "had them for 10 years" wasn't a straight one, which made me even more suspicious. if that's really how long you've had them, you obviously got them used, which makes a huge difference. finally, i hoped to confirm the age by simply asking for the stamp info, and of course you left out the dates of manufacture and the original hydro history, which would've given an accurate age.

from the other info on the stamps it's pretty obvious that they're 20+ years old. not only that but at least one is made out of that troublesome Alum 6351 alloy.

if you've been in commercial diving for so long, you either: 1. know about these issues and are being a jackass by trying to pawn the tanks off on someone who doesn't know any better, or 2. you're really fucking stupid. do everyone a favor and be up front with your shitty gear in the future. hell, i might've still bought those tanks from you knowing their age, but the mere fact you tried to hide it makes you untrustworthy.
