I don't think you understood what I meant - I mean why would you want a digital gauge at all? It's expensive, more likely to go wrong, and often quite inaccurate. I'm yet to find a piece of electronics with some sort of computer chip in it that has been reliable, so why would you want an electronic display telling you how much longer you can breathe for, rather than a needle sliding up a scale? If you want one then that is of course your choice, but I'm just interested in the advantages that you see in a digital gauge.
I have over 200 dives in the last year using an air intergrated Vyper Air. Bottom line, it works.
