Garmin Descent x50i experience?

So I’m not sure how to download the dive, but the Garmin Dive app does show a little more data.

You can connect the device to a computer with a USB cable and copy the FIT file directly (just like a flash drive). Or if the activity has already synced to Garmin Connect then you can download the FIT file there. Post a copy here and we might be able to figure something out for you.

Looking at my MK3i under Dive setup in the Garmin Dive app, the GF is shown next to each selection. If you select Custom, the default is 35/75.

Attached is the file. I was not able to attach it directly so I renamed it as .zip (I did not actually zip it). You will need to rename back to .fit to use it.

I uploaded your file into FIT File Viewer. It shows Low GF % = 97% and High GF % = 97%. Those are technically valid settings but quite odd and not something that most divers would intentionally pick as a custom conservatism setting. The really weird thing is that at the start of the dive you were already at 108% N2 loading, so you were past the NDL when you entered the water. At one point you had over an hour of deco, which obviously doesn't make sense.

You're probably dealing with some kind of device failure so you'll need to contact Garmin support. It's possible the device had some kind of pressure sensor or software failure and either it never cleared nitrogen loading from the previous dive, or kept accumulating during the surface interval due to thinking you were at a higher ambient pressure.
