Re: Frog abandonned...

The big difference between OSTC and Frog is that the first one is open source. Even if they discontinue it, some skilled people might be able to release a firmware. Frog was not open source therefore the upgrade options were limited only to the manufacturer.

I don't think it is necessarily a ...

Re: Questions about Nofly computation

It's about calculating for each tissue the atmospheric pressure limit you can't go below considering the saturation of each tissue. Then you keep the highest calculated pressure from the previous calculation and apply an atmospheric pressure to altitude conversion formula. Atmospheric pressure might ...

Re: Questions about Nofly computation

I don't know if cabin pressure loss are common. Luckily, I've never experienced such as thing despite a dozen transcontinental flights each year.

It's hard to tell what would happen between the effect of ambiant pressure and exact amount of O2 in your oxygen mask, also considering that the plane ...

Of course… but it can take very long time!

Yes, with the rule that the longer you wait, the safer it is in mind and that all deco model are just real-time simulation of body saturation and certainly not the truth (ie your real desat level), I believe that the most ...

Re: Questions about Nofly computation

Have a look at for no fly computation
http://www.achim-und-kai.de/kai/tausim/saett_faq_e.html#k5

On the DR5, I reprogrammed the unit to show no deco time and max altitude. No Fly time is still visible somewhere but it is of no use for me. Assuming everything goes fine, air cabin pressure is likely ...

Re: OSTC 3

- The OSTC/DRx/DR5 sensors are from Intersema/MEAS. This is a swiss manufacturer.

- Many dive computer manufacturers use sensors from this company (e.g. Suunto, UEMIS). Those manufacturers are not exempt from trouble with these sensors.

- The "Made in Switzerland" like any product from any other ...
