    For your situation, yes, trimix analyzer should be very high on your list. Because you can get a fill and not know what it is and the shop doing the fill can't tell you either. (topping off a trimix fill with air).

    Still comes down to what level are you at. Doing trimix, sometimes getting an air top off, you need to know.
    But just doing Nitrox, any shop doing a nitrox fill better have a good tester. Or get an inexpensive O2 analyzer.
    There just isn't a single answer when you are mixing apples and lemons. Are you talking about $100 for a little O2 testing, or $700 for a second computer or a trimix analyzer? Can't lump those together.

    My beloved Michigan has the longest coastline of any US state. :D

    That would be the second longest shoreline, not coastline. :wink:

    It’s on my list. But I don’t need to get it now. Class deco dives won’t be until next June-July. Another deco bottle and a Thermolution heated vest are higher on the list. I can always just get all air fills at DRIS after class until I have an analyzer. It’s just an hour each way (minimum with no traffic, 90 min with traffic).

    <My process works for me when it is MY TANKS NOT LOANERS. I should have said that from the start. My fault.

    Haha. Correct. I always forget about our brothers to the north. Probably not a lot of divers up there. I'll restate, longest in the CONUS. :wink:

    Say you have 90bar of 18/35 and get an air top to 230 bar, you will end up with something like 20/13 or 20/14. I claim that is essentially air.

    Having said that, I like having a trimix analyser.

    You mean in Michigan? I thought I read somewhere that Michigan was early with adoption of the diver down flag.

    What three more regs? I’ve already got a set for my doubles and a deco reg. I’m pretty much fully equipped already. All I need is a heated vest, another AL40, and a primary light (forgot to mention that in a previous post). I’ve been very careful with my purchases and bought what would work for tech.
