Sorry don't mean to hijack but why hasn't someone put a small LCD display to show the actual PO2 on a hud? Only the LCD would need to be housed I,d assume electronics to run it inn the head.

Please bear with me I,am new to this and trying to learn

Hi Paul,

For me the difference is seeing what the PPO2 values are as you breathe. The slight fluctuations that show the cells actually shifting, albeit by small amounts.

HUDs are a great safety feature, but they generally give you a 'Within Setpoint Range' or 'Out of Setpoint Range'.

Even the Smithers code HUDs do not give you the visual information that a glance at a display can provide.

HUDs significantly improve diver safety IMHO, for me they are there to compliment the displays, not the other way around.

Cheers,

Dave.

P.S. Not long to go now!
