    DRIS has a Solo on display and I looked it at yesterday. I realize how spoiled I am with regards to my shop.

    Point taken...having said that...some dive destination shops are mobbed...especially on weekends...it could be a long wait in the queue waiting your turn for the shop analyzer...

    My dive destination of choice does all their filling at night after the shop has closed...there may be 50 divers at the shop when the doors open on Saturday morning...all wanting their cylinders...and all needing to analyze their mix...

    I have an A-II Palm...excellent/inexpensive investment...and great time saver...

    And...why two computers of the same make/model...two potential inherent flaws...two computers down instead of one...

    I just asked them about the difference at the Midwest conference. Basically the Solo doesn't have the advanced features like a voltmeter for checking cells, etc. It just analyzes the mix.

    She already has a pile of cylinders.

    I can also tell you about the club kit which may or may not have had labels removed or been re-analysed when used 32% is topped up with air. In that case the shop might not have an analyser, you might not be present at the fill.

    Actually, that is a great example. We regularly dive in Pembrokeshire over a bank holiday weekend. The diving is usually quite shallow and it is a good opportunity to get new divers some experience. The skipper organises the fills. At the end of the day we put cylinders on a big trailer and they turn up magically filled the next day. Sometimes he can do Nitrox, sometimes not. Part of the training for Sports Diver is a nitrox dive, so taking along some cylinders of Nitrox is a good plan. Once those are used they will get an air top, overnight at the hands of the skipper. Analysing that resulting mix is best practice.

    It did once happen that I was given a dil cylinder full of oxygen by this process. Fortunately I analysed it before getting on the boat and so had a chance to sort it out.

    Analysers are not expensive, you don’t need to be a ‘tech’ diver to think of owning one any more than you need to be a ‘tech’ diver to plan your gas consumption.

    If is important to be sure what you are breathing is what you think it is.

    Gas logistic errors happen all the time. People really do die from not know8ng the mix in a cylinder.

    Primary computer failure fatalities? Not so many.

    Best way to spend money, 1/4 the cost on the more likely issue, or the whole cost on the unlikely issue? Hmmm tricky...

    The answer to me is easy... analyzer first. Honestly, I would suggest an analyzer before buying the first computer.

    Dont get me wrong, computers are cool and make life a little easier, but they aren’t nessecary to begin with. You can do a sh1tload of deco diving on a bottom timer and some wet notes. I get a kick out of folks that think they “need” a backup computer. Unless they are exploring Twin Dees, I contend that they don’t need a computer at all. Save that money and spend it on actually diving. If you find a point where you have $1000 laying around that you can afford to set on fire...then buy yourself a computer...or 2.
