I am also saying that there is never any excuse to run out of gas unless you pop a low pressure hose
Don't you mean a high pressure hose, your tank will empty fairly quickly in that scenario compared to a low pressure hose ?
Also, what I am saying is that relying on wireless kit underwater (which all Suunto integrated computers use) without having an SPG and depth gauge is stupid.
Couldn't agree more, always have redundancy. I carry a spare mask, such a simple thing but a really unpleasant thing to happen if your mask gets knocked off and you lose it.
