    I love mine. I use it stand alone, but the procedure is simple.

    I just got a CooTwo a week ago. I have not used it yet. I plan on using it with my iPhone.

    My old O2 and CO meters each failed within a week of each other for dramatically different reasons. Faced with buying two new analyzers to replaced the broken ones the CooTwo made the most sense to me.

    The only time I use the shop analyzer is if mine is not available.

    At 50 dives, I thought I had this diving thing figured out. At 100 dives, I realized how wrong I was at 50.

    I own couple O2 analyzers and a He analyzer since I do my own basement blending. I'll usually always use a shop analyzer but I double check mixes with my own.

    I don't own a CO analyzer unit but am thinking of picking one up. Question for those with the Sensorcon CO analyzer...Does it work OK for analyzing scuba tanks?

    I had one, and it seemed to be good. I could "blow" a positive number, but it usually read 0 on my tanks. The one exception was when a shop had a problem, and warned everyone not to use gas from that one day. My Sensorcon read high, so I am pretty sure it is safe to rely on it. I got a Coo2, because it does both CO and O2, and sold the Sensorcon.

    I've got the Sensorcon as well and, like Forrest, can blow a positive number, but all of my fills have always read zero. My LDS has an O2 sensor that we verify the fills with when I pick them up, but they don't have a single CO analyzer in the building. The first time I got fills there, I didn't own a CO analyzer yet, and I was nervous as hell the entire dive trip. Their explanation was that they "passed all of their quarterly checks and have never had any problems."

    Well, you never have problems until you do. And the likelihood of it happening the day of your quarterly check instead of weeks or months before is well... ya know.

    I also have a Sensorcon; it works fine. It came with a scuba adapter which consists of a plastic DIN cap with a hose and a T-fitting that attaches to the inlet of the analyzer. I'd guess that it would work just as well without the adapter.

    It is overdue for calibration, but I haven't bothered to get it calibrated as my breath always reads 1-2 ppm and all of my scuba gas so far has read 0 ppm. That seems adequate to me.

    Blowing a low CO number on exhaled air is normal, especially for older people. Our metabolism generates small amounts of CO as well as the normal CO2.

    Life long smokers will frequently blow 5-10 ppm CO in exhaled air.

    See section #6 in link below.

    I use my Sensorcon with a breath bump test, same as Morgan. Mine also gives me the nag screen for recalibration but it seems to work fine otherwise. With things I've heard from other users, I don't dare send it in for a re-cal. It might not ever work properly again.

    I also have individual O2 & He analyzers that get used whenever a shop analyzer isn't available, can't be trusted, or just isn't convenient.

    The most powerful minds are the ones that can be changed.

    For Tech/Cave, I analyze on the boat, or at the bench, even if I just analyzed the same bottle 15 minutes ago at the shop. For recreational I analyze before I leave the shop, and mark it with my own brand. If tanks don't go from shop to boat. I store them at home, and reanalyze when I pull for use. My usual buddy follows the same protocol.
