Crashing would be the least of the worries in my opinion. If it crashes, you as a diver know what to do and it’s no different from any other dive computer breaking.

My major worry would be bad sensor readings or software errors leading it to provide bad instructions on how fast you can surface, or how long you need to do decompression stops. Depending on the dive, it’s a situation where differences in the displayed numbers mean the difference between a great day and serious injury.

I really hope; but also expect that this is thoroughly tested.
