That's all the pictures we have. We were supposed to meet the photographer today, but he didn't show. We should have more pictures in the next couple of weeks.

The box part is 1.5"X2.5"X3.25" (38cmX63cmX82cm).

You have a couple of choices. You could just piggy back the pins into the existing three sensors. But I would probably put a 4th sensor in. The Meg Shearwater only uses one battery box, so there's lots of room for a 4th sensor. You can just use a 9V battery clip or something like that to hold it. Then leave the other two molex connectors hanging.

On normal diving, you would have a completely independent PPO2 monitoring system. If the primary system fails, and you are in Truk Lagoon, you can keep on diving by plugging all three plugs into the main sensors and recalibrating.

In terms of redundancy, I am much more worried about the O2 sensor failures than electronic failures, so the independent sensor is attractive to me.
