Re: simple HUD I'm still happy with Uri's unit - we've done a few mods to make it even more MCCR friendly (which I'll post after anothe couple of dives - tommorrow hopefully).
It gives me a simple green=OK type signal with easily understood flicker-if-high, flash-if-low, add red if far out of range sequence of signals. It is very easy to understand under water and gives you outputs of all 3 cells.
