    DiveNav has now closed for business which leaves owners of their products looking for replacement sensors and batteries along with calibration gas for the CO testing products. The original CO sensor is made by DD Scientific in Great Britain. The sensors are reasonably priced but shipping directly form the UK is quite pricey. The O2 sensor is available widely but generally costs around 80 USD. A US distributor has recently opened up shop and can supply these sensors at a very reasonable price.

    The sensors you will need are
    CO sensor is part number S+4 2ECOH (it is the exact part found in the COOTWO)25usd
    O2 sensor is part number S+AOX (it is an equivalent substitute for the part found in the COOTWO)30usd
    shipping is 12.95usd
    Both sensors including shipping will run you 67.95usd

    These prices are valid if you are willing to wait to add it to another order that they have coming from UK. They order about every week. With demand they will begin to stock the part. If you ask them to order one immediately the CO sensor will be 60usd.

    Tiffany is delightful and very helpful. They have a wide array of gas testing supplies.

    If you need to calibrate a CO sensor you will also need bump gas. I got mine from Grainger to avoid shipping charges. They have 17l and larger bottles. This is the link for 34L https://m.grainger.com/mobile/product/GASCO-Carbon-Monoxide-24VN14
    You will also need a regulator valve and a method for metering it into the device during calibration.

    I will sticky this thread for future reference and will allow additional posts that have additional information on service and supplies for our orphaned products. I will come in later and clean up any posts that are just attaboys. Hopefully we can keep this page clean but further discussion can continue in the original thread from which this one was born. It can be found here.

    I had the same issue and just popped one of these in today. Worked like a charm.

    The O2 sensors are standard dive sensors. Many people, myself included, "retire" their CCR sensors into O2 analyzers. My Cootwo currently has a sensor from my Meg in it.

    Thanks for helping to round out the details. I don't have CO/O2 meters but use some of these things in my day job so wanted to make sure that everyone is aware of additional items needed for their specific meter and cal gas tank combo.

    @tursiops that rotometer should work as a less expensive alternate.

    DiveNav says the flow rate through their ball at the end of the Cootwo is limited to 0.5 l/min. So any flow rate higher than that is probably OK.
    The Sensorcon flow calibration rate should be 0.5 l/min (but you have to limit it yourself), so that's a good all-around number.

    Well I went ahead and bought a CO and O2 sensor through Tiffany at McNeil Int. The total with shipping to Indiana was just under $68. The sensors arrived today and things looked to be in order. The CO sensor looks identical to the one in my Cootwo and of course the part number matches. I did not install the CO sensor as I am waiting for my calibration gas to arrive.

    The O2 sensor is slightly larger than the OEM version but not by much. The only main concern is that the base of the new sensor is shaped differently. I was able to easily squeeze it into the housing which then allowed the front and back pieces to fit together. Once reassembled, I used the app to set the installation of a new O2 sensor and then performed a calibration. The calibration process was normal, and I successfully tested a couple tanks. I didn’t have any mix gas on hand so I couldn’t confirm anything other than just air. The O2 sensor from DD Sci. seems to work just fine and at $30 a piece it’s hard to beat. I’ll follow up on how things go with the CO sensor once I have the calibration gas.
