    I don't blame Paul, not at all - I'd be madder than a cut snake if I were on the receiving end of it.

    Just suggesting an alternative coping strategy, is all. :)

    Thanks Paul And Bruce for the lesson in calibrating in air, to think some other Manufactors are bragging how great it is to calibrate in air. Can't wait to hear from their fanboys.

    But I actually learn things from Pauls responses.

    If you can see the tree though the forest, Paul and others like Bruce, when they choose to respond (even in this environment) still bring data to the table that is good for the board.

    I believe, that the calibration air, is valid if we consider the deviations and the response speed of the microprocessor, the micro-variations are continuous. I have used many rebreather ,calibrated in air and O2, i have not noticed significant changes in reading. I am not referring to the specific case, but I think the air calibration should be seen as "The biggest error in o2 sensor calibration can be made ​​by the user", then as a simplification to avoid wrong gas or other stupid things. That's it, it's clear more accurate the reading will be better, but the reading is dependent on a multitude of parameters including cell o2. Bruce is surely right, but any electronics/calibration will deviate.

    If only we could get Paul and Bruce to agree to a monthly "random fact about stuff" post, it would be a lot less painful for everyone :)
