ScubaJim,

On your behalf we just contacted ScubaPro Corporate. They gave us a definitive answer that an Oxy2 that has a corroded PC board indicates water infiltration and that cannot be serviced as they have no access to replacement PC boards.

The manufacturer, Uwatec has not made the Oxy2's for 4 years now. ScubaPro will still change batteries, etc, but when it comes to parts, your out of luck.

They did say that Uwatec will not accept a return for repairs.

If you cannot find some used Oxy2's, then you can use Draeger's Oxyguage to monitor P02, or you can check out the various homebuilt means of monitoring Po2 with a VR3.

We have Paul Raymaekers on the forum here who prodcues the rEvo and I believe they produce a means of monitoring P02 for Dolphins.

Perhaps other Dolphin divers can chime in here.
