Spot on buddy!! I agree. I have been in enough zero vis in wrecks, caves, muck inland lakes and black rivers to have a high degree of certainty that I could see my HUD. The only place I doubt I could see my HUD would be in the bottom of Breavort lake in Michigan. Doing salvage type work like that in not a place for a CCR.

Cheers!!

No I have not been in a wreck silt out, but have been in cave (fine clay) siltouts where vis went to 'zero'.... I could still see the glow of my lights and gauges......but could not read them. That is what we are talking about here.

We are not talking about reading screens/gauges, but being able to see the HUD or at least the glow thereof to discern what it is telling you.

I do not believe that, short of physically blocking the HUD, one would not be able to see the glow and thus make out PO2 status in a zero vis situation.
