It does work!
We have been working with the developer of Dive Log for quite some time (they have integrated into Dive Log support for our DCbuddy BLE device) and they are quite good!
Yesterday I finally had a chance to dive with my new Petrel 2 and not only did the computer work flawlessly (it's so great to be able to clearly see all the info needed on one screen and all the other dive details with simple single button presses), the direct download into Dive Log worked equally as flawlessly. It's really great to see my dive profile along with all the other pertinent information in my digital logging software. Thank you DiveNav for that and thank you Shearwater for an amazing dive computer.
