One word: trust.I don't get the hype and hope for Solid State O2 sensors.
Rebreather manufacturers have done an awesome job working within constraints of galvanic oxygen sensors (and developing rules to reduce likelihood of multiple failures at an inopportune time) but when in comes to anything giving life critical readings it sure would be better if failed sensors gave null readings instead of lying..
