| Nawty,
I am sure my Gekko has 'basic' dive planning. I.e. I can, whilst on a surface interval, put a depth in the computer and it will tell me the NDT for that depth. It is simplistic, as it works on one depth for the duration of the dive, but seems to suffice.
If you are sat on the boat, and you know the next dive is at 25m, you can easily see how much NDT you have at 25m. Is this what you want?
