For the Garmin Descent, the way it's currently done is that start/end coordinates are captures as "extra data" strings, with a key of GPS1 and GPS2 respectively. End result: the data does get saved, but only the last coordinate is then used for the dive site. So I agree, there's no huge hurry about this. Looking at the actual data I do have, it does seem to be (a) more than precise enough to warrant showing on the map and (b) not useful as a _path_. For example, I did Blackrock in Maui as a "drift" dive (ok, so it took an hour and a half to "drift" a few hundred meters because there was no real current), and for that dive I got keyvalue "GPS1" "20.928930, -156.695058" keyvalue "GPS2" "20.926903, -156.696113" which if you look at a map looks exactly right, but if you draw a line between them it will go straight through the Sheraton Maui, because obviously the actual dive is *around* the rock. So I think Dirk's argument that we don't have good enough GPS location is wrong - but it is true that it might be hard to show them sanely. I think the Garmin Connect app showed the locations as a red and a green marker. I'm not sure that's great either.
