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
The original COPIS had a "feature" that caused it to lose the calibration when the power was off so therefore required recalbrating every time it was powered up. The new COPIS II retains calibration data.
