I was recently doing some work for a friend who, lamentably, went eBay foraging, for "a deal'" much as I tried to discourage him. The listing was from a seller, supposedly located in the Midwest -- by Midwest, I hope that I made it clear, that I was referring to Oslo, Norway, which turned out to be the physical location of the items, which came as quite a surprise to him. "Oh, I didn't tell you?" was the seller's response.
Apparently, eBay now allows for a 7000 kilometer margin of error, in terms of a seller's location . . .
My friend dropped by a box, barely held together with strapping tape. Inside, was a Poseidon Atmosphere mask from circa 2010; an older XStream first stage; an XStream octopus; a Cirrus double gauge; and a few low pressure hoses. He asked me about my first impressions; and I told him that the hoses seemed quite nice.
The mask and second stage free-flowed uncontrollably, when the regulator was pressurized, as everyone in the room anticipated; but there were more significant things to consider. The IP, for example, exceeded 12 bar -- higher than even the specs for the Cyklon; and was creeping upwards.
The following photos illustrate what I have typically seen, in terms of most used equipment -- and the pitfalls often associated with it. It is rarely ever a deal . . .
The first photos depict what appears to be vermin damage to the Atmosphere inner mask. It appears chewed. Other photos include corrosion to the seized valve assembly of the Jetstream PP; corrosion to the pressure plate (actually pitted; I have never seen that); the corroded adjustment screw; the OPV, which required a full twenty minutes of ultrasonic cleaning at 50˚C to even remove the valve piston from a solid plug of salt; and spectacular corrosion to the combined upper and lower pin guide, a part which no longer exists in quite that form. What wasn't shown, were the slew of o-rings, which could not be removed intact; that, and several grams of sand in the FFM; and the Atmosphere's visor clamp, a total loss, its screws forever rusted in place.
Afterwards, I had to take a hose to my work mat, to remove the filth.
In his pursuit of a bargain, he now has an invoice for several hundred dollars in replacement parts, should it even be restored; and a good amount of labor, if I really put the screws to him, for not taking my advice. Also, since the first stage is an older model, it requires a specific upgrade kit -- something my friend never even considered or heard about, while impulse buying . . .
