I searched the forum and noticed that there has been one older topic related to this but not fully to my needs.
I've got a Garmin Vivosport that tracks my heart rate (its water restistant till 50 meters, so capable for diving). It can export files as .fit (i cannot add it as an .fit attachment as its not the right format, so added as .zip - you need to extract it first). I would like to know if I can merge this with the dive imported via my Shearwater Perdix AI? I tried importing the .fit file via the garmin importer, but failed to do so - 0:1 dives imported it said.
I think it would be best (for me) - if it can be merged as profile 3.
Any ideas?

Thanks a lot!
