Hi,
Why is it not necessary to calibrate the COPISII every dive? or is this irrespective of the type of unit - depending on what/when you are diving etc?

Thanks

Why would you re calibrate a unit that was already calibrated correctly? My hammerhead can go weeks between calibrations. The calibration gets checked before every dive (air and pure O2) but it doesn't get re calibrated unless doesn't match the known gases.
