Shearwarter AI+GPS location data missing

[Doug Ray]

I recently added the Shearwater AI+GPS to my kit. Subsurface reads the tank pressure fine but I don't see where it captures the GPS data that I see in the Perdix 2 dive log. Is there a way import this as well?

Also, not really a problem, but diving with double-manifolded cylinders and one transmitter, I find I need to report a single cylinder with twice the rated volume (LP108, 216 cf) to get SAC rate calculated correctly. Is that the best way?

What version of Subsurface / operating system / operating system version
are you running?

There are pre-defined double sets as D8.5 / D12 / D13 / ..., but they
might not be the size you are using.

Hi Michael, 

I upload my dives from my Shearwater computer to Subsurface-mobile V:6.0.5504 because I found that Subsurface desktop version, same version number, was having difficulty connecting to my DC. I can then upload to the cloud and view from desktop.,

It looks like the D13 232 bar set is close but not quite same so I'll just add that manually.

Thanks,

Doug

Yeah, this is a bit too old to have GPS support for Shearwater dive
computers. Try a nightly build from
https://subsurface-divelog.org/latest-release/.

Yes, dive tanks are not really standardised - most of them are close to
the pre-defined sizes, but not quite there.
