I was on my first scuba diving trip with a brand new Garmin Descent G1. The very first dive was not recorded as I forgot to click save at the end of the dive. However:
- The watch worked fine during the dive
- The surface inteval was correctly shown (hence it knew I went diving)
Basically, I lost the whole data for one dive. Worst, I do not know if this dive was included in the calculation which could be downright dangerous. I had four dives on that day and I have no idea if the first one was even included.
On the image below, you can clearly see that the dive was taken into account for the Surface interval but was not recorded.
