Hi Mikel,
I think with regard to your sensors, you can find a chart that gives the pressure at that altitude, and then just set your calibration to 21% of that pressure.
I think it is better to actually measure the pressure when you are there, and act accordingly.
Then for deco, most computers would be able to figure it out if you set them to altitude. Something to beware of, not all the computers take into account whether or not you have acclimatised to the altitude.
Tables made by software can also do it.
Best to add some safety fudge into whatever deco you plan.
I am sure someone will come along soon with better details

Sorry, but do you mean that i 've to know the mb in this altitude (pj: 1030mb) and in the moment that i'm calibrating the Rebreather thell him that there are 1030mb and keep on calibrating?
I've a VR3 that i think that it takes the altitude automaticly.
Thanks for your help
Mikel
