I was going to say something about fool-proof interfaces versus the ingenuity of fools, but it would sound flippant.DandyDon:But I've heard it on the boats: My computer beeped down there? I wonder why?
Given the title of this thread, it's important to remember that no dive computer is safe if you don't pay attention to it while diving. Or if you don't know how to interpret its display.
I heard a sobering anecdote (I've forgotten the source) about someone who incurred a deco obligation while diving with a Suunto computer. He interpreted the "STOP" display (which means you're going to have a mandatory stop higher up, later on) to mean "stop here, now." And patiently, foolishly waited for the display to change while using up air and going further into deco.
