When I took the class I was not given any option. The unit came with a single fischer connector for a shearwater. Edd did not give me any options or discuss any options with me. Going into the class at the time there were very few discussions on the unit since it was fairly new. Nobody talked about the options available, including Edd. So going in I just went with what Edd said was standard and what "everybody" he was putting in the unit was using. I don't like having just one p02 monitor. It may not be necessary in some peoples' eyes, but I feel it's important. The reason I worded my response to the op the way I did (discuss with the instructor first) is because I wasn't given options. I was just told this is how it comes. Maybe that's changed, but it is still a very important thing to discuss imo.what single PO2 comes stock?
Because you can say that but it's not correct.
The unit comes with the PO2 monitors that the users chooses, including none if they choose that.
I have looked at the Ginnie death, the conclusion many have come to I do not share
As for the ginnie death, the sw didn't kill him. It was a factor. His carelesness and (potentially) lack of experience for the diving he was doing (that is my opinion, so why I say potentially) is what killed him. Based on everything I know of the death (and I've been privy to all of the details) is that complacency/distraction is the culprit, but the inline shutoff and lack of secondary p02 monitor were major contributing factors. As I said before, not every diver is perfect. I know I'm not. So having safety nets is nice.
