Chaps,
I just wanted to share this and see if any one else experienced a problem and if they did so they knew what the short term fix was.
For me it was a minor irratation that the HUD failed, the unit was still diveable and I did put about another 10 hours on it.
The reason you had to wait over 24 hours before swtiching both computers off and resetting is so the Shearwater does not loose your tissue loading and screw your deco up! Incidently to prevent it hold the ballast out to the side when you switch the torch on.
I think its great that the PRISM has been tested against this - but one of the things I love about the Meg, Bruce and Leon is if you tell them about a problem, then they work on the fix and within weeks release it!
For the record I don't think any unit is totally perfect and would not want to hide the fact I had an issue on my Meg, if I had wanted to I would have just spoken to Leon and Bruce on the quiet.
This is the only fault I have had though and I am sharing it with you all - I would worry far more about poor build quality or parts breaking or maybe being able to put a scrubber unit in upside down

it is my belief that no unit is perfect and what is the correct unit for one person with their very subjective scoring evaluation criteria will be different for others.
To end on a positive note on one dive some numpty dropped a cylinder on my shearwater hand set and.....nothing happened.
Now I'm off diving for the weekend *waves*
