Hi, Today I downloaded all my dives (since the Shearwater upgrade) with the latest qt-6 nightly, including the libdivecomputer log (see attached). I’ve added all of them to give logs with different tanks, gas mixes and usage.
Sunday I had a dive with a “close call” (feel free to ask details off-list) where I actually had to do a bailout on two gasses. So the log from 03/12 should give a “nice” view of a CCR dive. Unfortunately Shearwaters own application makes it very hard to read the details that, especially now, I would like to look into. Hopefully this data helps a bit more. — Attilla > On 17 Mar 2023, at 09:21, Attilla de Groot via subsurface > <[email protected]> wrote: > > Hi, > > Last December Shearwater fixed an issue on the Petrel3 that put a lot of gas > changes in the dive log.
