    If its a good deal then go for it but there are a few things to look out for. The computer is an older one so if somthing breaks on it you might not be able to get it fixed. That is the biggest thing. With a lot of computers now a days you might be better off buying new. The Oceanic VEO 1.0 is a great computer at a great price. It all depends on how much you can get the DataMax II for. It you are paying more that half of a new computer I would get a new one. Good Luck.

    The timer can fail the but depth gauge cannot. This means you can terminate a dive safely even with a completely blown device, then strap on your wristwatch and keep diving. Then you can buy the Veo, which incidentally, I don't like.

    I know this is a very old post, but I own a US Oceanic DataMax II and it is a dive timer, NOT a computer.
    I bought mine when Nitrox was just starting to emerge in the mid 80's. I liked these units, as the tables were being changed at the time, Nitrox was brand new & there were A lot of computers coming back to the shops, ruining many dive days & even trips at the time. My thinking is to keep it simple! IF I needed a separate computer, I could buy a computer for air &/or Nitrox at a later date. I've been on my Oceanic DataMax II for many years & I STILL love my old console w/ my bottom timer/depth gauge w/ the max depth "idiot needle" & tank pressure gauge. (I have a separate small compass that fits on my watch, which I've always had as a back-up, yet only needed once when my battery quit.)

    I've always been one to have back-up systems, as I've done a lot of cave, wreck, drift diving & work, thus always been a stickler to have that extra bit of technology, yet at the same time keeping it simple.

    Hi, I have a Datamax 2 that I would like to trade in for a newer model.

    Why? That computer does everything the newest and much more expensive computers do, with a few limitations that don't matter for most diving applications.

    A bit late to the game here but I just received a DATAMAX II and decided to try to ressurrect it.

    Changed batteries according to the steps earlier in this post. All went fine but the DE grease seemed to cause some issues. Guess it was pretty dielectric!. Cleaned that off and got the clock to turn on but it was a bit hinky in going from DIT to SIT.

    Took it on a dive (put it in my goodie bag) and it never really started timing my dive...just stayed on SIT. Then it just shut down.

    Suspected dirty contacts so I cracked her back open and the contacts looked fine but I grabbed the tried and true pencil eraser and scrubbed all the contacts. That did the trick.

    So here's what I found on the operation:

    Dive timer remains visible for about 12 hours after the last dive at which time it blanks out and apparently resets the dive number at this time as well.

    Surface Interval Timer remains visible for 24 hours after the last dive at which time it blanks out and resets.

    Obviously no ability to recall prior dive data.

    I'm sure this isn't the endallbeall for the DataMaxII but hope it's helpful!

    If anyone happens to have a printed manual for this unit i'd love to get a copy!
