    The full scale business is mechanics. The guts can work over whatever range you like, but the visual only needs to go to 300bar.

    I wouldn't use the psi gauge unless I was in the us. Like I said - very limited market. It's a risk to be aware of though. If the yank has lots more gas then you to start with and you both divide by three. He breathes more and then has a problem - there is insufficient gas in your tanks to get you both out.

    Give the Yank a slap and throw a bar gauge at them telling them to pull themselves together and enter the 20th century.

    350bar is good for cave divers...

    Never blow hot and let it cool?

    Simple black on white, please. If you must, a red bit at 50bar.
    Why red to mark the 50 bar? You can't see red below, say, 8 metres and it appears black.

    why not, for example, use a double === marker for 50 bar. Or some other non-coloured indicator to highlight the 50 bar - invert it? [50]

    Why not let "50 bar" indicate where 50 bar is?

    RED indicates the least accurate section of a gauge apparently. well thats what a clanky spanner flinger told me many years ago

    No red please. I do some dives where the red should start at 20bar, I do other dives where it needs to be at 150bar.

    Exactly. Red at 50 bar is just an arbitrary number. I have a gauge where they've decided to put it at 70. The numbers all need to be clear and in the same plane though rather than rotating with the dial.

    Ali 80 FS.

    I really hope this happens. I prefer glass as they're easier to read. But I break em.

    Plastic uns scratch up where I go and get impossible to read.

    Either way, I buy often. But the glass ones I buy (DIR direct?) normally will still work enough to get you home when the crack. When the plastic ones get scratched, they're just not readable at all

    Cheaper, simpler and no boot is all I want.
