the fathom hud has the disco mode and the low/high po2 range can be programmed. i don't think others have it. the regular shearwater hud doesn't.Could other people chime in on this point?
My understanding has always been that the whole point of huds (for example the narked@90 one) is that once you ppo02 drops or climbs too much, it will go into a disco mode and warm you.
Does it actually happen that you become so used to it that you can ignore the warnings?
i would consider a hud mandatory
