This seems to be the best place to discuss the SDA that I've found. So here's post number one from me. Hi everyone. 
I received my SDA yesterday, and although I haven't gotten it wet yet I've been reading through all the instructions like a good boy. It's left me with a few queries though. Can anybody answer them for me.
1) The manual says that the safety stop will kick in at 2x the depth set. Does that mean if I set 6 metres that anything above 12 metres will count as a safety stop? or does it only start counting near the safety depth?
2) I can find any mention of what ascent rate the SDA treats as the maximum. 10 metres / min ?
3) What's the "Global pO2 min" setting do? "Maximum" I understand, but I can't see why there would be a minimum set at around 1 bar.
That will do for now.
Thanks
