Hi, CF39 is most useful for mCCR guys (but not only for them) I dive with a rEvo III mCCR. I have to maintain ppO2 manually, so it's possible that the real ppO2 is sligthly under the targeted ppO2. So I take a safety margin for deco calculation. My target ppO2 is 1.3 As a safety margin, the OSTC set...

I'm diving a rEvo mCCR with hardwired Shearwater predator (reading the cells), with OSTC as backup for deco I'm still a beginner with the rEvo (30 dives only and only air as diluent until now) and now I'm diving this way (controlling MANUALLY my PPO2 with the kiss valve flow and add O2 / add dil but...

Heu... Tu as déjà plongé avec ton ordi ?
Tu peux voir tes plongées dans le logbook interne de l'OSTC ?

The blue LED flashes until no-fly time comes to zero - you have also the no-fly time displayed in surface mode.

For question 2, I don't know

We could expend this case to a more general : Would it be possible to have a second set of GF, less conservative than the chosen values in CF32/CF33, for critical situations (bailout, OC gas problem, whatever) - the idea is to switch underwater to this set when you dramatically need to go as soon as...

This Winter I've dived in waters as cold as 1 or 2°C (during the whole dive).

Does not seem to affect the OSTC.

Hi all, I've an OSTC mk1 (v1.60) I use it for trimix dives and also, most of the time, for air/nitrox dives. I don't use the same GF for a trimix or an air/nitrox dive - typically I use 30/80 for trimix or 80/80 for air/nitrox. Discussing this point is not the topic of this post. When I do an air/ni...

Great !

Hi, I've a mk1 OSTC with v1.60 on it I tried today the new CF42, with the blinking of the current gaz if a better gaz is available. It worked as expected, but I find that the blinking doesn't attract too much the attention to it (not so visible) - I would like to have a more visible blinking. Sugges...
