OK. I am listing what the computer comes with............the computer itself, case, and a disc which I assume is the software. The computer is unconfigured at the moment meaning it is an air computer out of the box, but can be upgraded to a variety of configurations listed on the Cochran link in the first post ranging from simple one gas nitrox to multiple gas nitrox with helium. In order to get it upgraded I believe you would take it to a Cochran dealer or send to Cochran direct. From what I was told by the dive shop that offered the computer on the prize table the upgrades ranges from $100-$400. Even if you go with the "Cadillac" version $800 ($400 to buy the computer and ~$400 for the full multi gas/helium upgrade) is a steal for a brand new multi gas helium computer.
As for the five posts in nine years comment it should not be an indication of the frequency with which I dive, or the veracity of this offer. I have been a moderator on multiple spearfishing websites currently with Spearfishing Planet. Go there and see how many posts I have if you feel my post count is directly related to whether my selling a brand new tech computer at a great price is legitimate or not. Since I actually go diving more than most I don't have the time or inclination to post on every dive related forum.
Call Cochran or a Cochran dealer and ask them if $400 for this brand new item is a good value. Whoever buys this is getting a GREAT deal.
Please PM or preferably email me if interested. I live in the Tampa Bay, FL area. Thanks....
