Actually, I prefer the "one per dive" model.

Sure, we can associate dive sites with gps coordinates too (and we
could just add them to the gtk tree model, so that when you pick an
existing dive site, the gps coordinates get filled in automatically if
they exist), but I personally prefer boat dives to shorediving by
quite a big margin, so most of my dives are off a boat.

And if I have the choice, and the companion app works well, I'd
definitely make the gps coordinates be per dive, instead of linking
them to some divesite registry or whatever.

I'd much rather I'd much rather just call the dive site "Molokini
crater" and then have the GPS location show where I entered the water,
than try to link the dive site. And depending on where you dive, the
same mooring well may be associated with multiple "dive sites"
(depending on exactly which part of a reef etc you go to), so you may
also have multiple dive sites associated with the same entry location.

Thinking that dive site and gps coordinates are somehow an 1:1
relationship is wrong.

I think the only real reason to link dive sites with gps coordinates
is "it's hard to get gps coordinates, so once you have them for one
dive site, look them up from the divesite". But that *should* be BS,
if we do things right. In fact, it should be easier to get the GPS
coordinates (since it can be entirely automated if you just have a
phone with you on the boat) than the dive site name (which tends to be
something that the locals make up depending on which part of the reef
etc).

Of course, then there are the people who just go to the same quarry
every weekend, or teach at the same exact site. They just don't care.
For them, having the gps coordinates per-dive might be redundant, but
the fact is, for that case you don't really care about the gps
coordinates at all (are you really going to look up the map of the
quarry you have gone to fifty times?), so that's not an argument -
that's just a boring special case, where it doesn't really *hurt* to
have per-dive gps data either (or no gps data at all, for that matter)
