it says it's rated to 40 meters, which is good for most recreational diving. This would not apply for deeper dives.

I'm curious to see what they have for using it with diver communication and collaboration. If one diver sees something of interest, they can easily notify other divers. I'm not sure if or how well Bluetooth works underwater?

The haptic vibration would be useful to notify about reaching maximum bottom time, and for decompression rest stops while ascending.

But I think I would still keep my traditional dive computer next to pressure gauge in my diving setup.

I wonder if they will have a wireless pressure sensor on the tank so you can also track air pressure and consumption? That would be neat.
