A first test version that includes support for downloading (via USB, on a computer) from the Garmin Descent is available.
There are a few shortcomings, still, but I think it's reasonably functional already. The two biggest issues are
a) no events are downloaded - this is simply code missing in our parsing algorithm and should be added reasonably soon.
b) the downloader right now offers ALL activities, it doesn't filter for dive activities. So unless you remember when your dives started, you may end up with weird super short/shallow "dives" in your dive log. Again, something I expect us to fix pretty soon.

You can find binaries here: <>

For Windows simply grab the subsurface-4.8.1-...exe - that's an installer
For Mac we don't have a signed DMG as we do for releases, instead there's a - which you can download, unpack, and then manually run (your Mac may complain about it being unsigned, depending on your security settings... worst case you may have to run the Contents/MacOS/Subsurface file directly
For Linux there's an AppImage there.

I'd be very interested in feedback how this works out for you.
