Joe, I'm not sure if it's "possible", but who really cares?  At this 
point, there are other options available (rb without electronics, OS 
scuba, don't do the dive).  O2 sensors and water area  bad 
combination, there is water in the breathing loop (mostly vapor), the 
sensor has to be in there too...unless you have unlimited funds and a 
really good reason, why bother?

The real problem is all these guys who think the rb's are the cat's 
pajamas, are strapped for cash, buy an inspiration and go to the 
great reef in the sky.  It gives the sport a bad name!

Cheers.
