Suunto Vytec depth anomoly

I had to return my Vytec as it showed depths as being between 3 and 5
metres shallower than reality and showed "Surface" while 3 to 5 metres
down!!

IT WAS NOT THE EARLY RECALL MODEL

Suunto replaced it and said they had never seen that before.

A friend of mine took his brand new Vytec to Grotta Giusti and only
registered 12m in the second traverse (a cave passage known to be 18m
exacly) and the other 6 divers all logged 18m on their computers,

At 6m, his Vytec proudly said it was at the surface, a definite proof of
a fault.

Has anyone else had this? Seems statistically improbable that 2 divers
from Standard Life Dive Club buying 2 Vytecs from 2 different suppliers
18 months apart get the exact same major fault.

Anyone else found the "surface" to be wet and unbreatheable

Nope mine is working perfectly.

It sounds like a hardware fault.

Yes, I've seen it. And I have a theory as to what it is, after re-creating
it.
On the back of your computer there is the computer download interface, which
doubles as the "in water" detector.
If there is a bubble on it before you get in the water, and your suit traps
it there, the computer does not realise you are in the water until you have
gone down a bit, when the bubble is compressed enough that the contacts meet
water. Then it starts reading depth, and I think it calibrates surface
pressure from that point.

I might be totally off target, but that's my theory as I have trimmed out
the cut out on the side and it has never happened again to me.

If you look back to May 2001, you will see a thread reporting a
similar error with a Vyper. The power was re-setting at about 3m. It
is at power-on that the sensors re-calibrate for surface pressure, so
if it powers off and then on again at 3m (or 6m, or whatever) it will
consistently give you a depth of that much less than the real depth.

I was not the only person to report this error, and the explanation
offered by Suunto for the *error* was fine, but they were unable to
come up with a good reason for the re-set phenomenon. Something about
a tiny smear of silicon on a battery terminal. Hmmmm... They
replaced it for me, and I just keep touching wood (gently) with it.
