I think I'm finally getting what you are trying to tell me. You are saying that even though Shearwater has announced they will offer the Petrel 3 with 4-pin connector, you are saying that they will not sell it to anyone except a CCR manufacturer.
You're saying that DGX and others will not be able to offer for sale the Petrel 3 with 4-pin direct to the consumer. Even though they offer the NERD2 in JJ, O2ptima, and generic DiveCAN versions, and you can buy the analog NERD2 with 4-pin connector (and 3 Molex connectors) from DGX as well (technically, a rEvo part, but anyone can buy it, as far as I know).
Shouldn't we expect rEvo to offer the Petrel 3 as an analog monitor with 4-pin connector, just like they offer the NERD2? So then you could buy it from DGX also?
If you're in a whiteout, can't see your Petrel 3 monitor, and you feel it buzz, what do you do? Dil flush?
If you're in a whiteout and can't see your non-Petrel 3 monitor, shouldn't you do the same thing?
Does having the haptic feedback make it okay, when you cannot see your monitor, to continue diving without doing a dil flush (presuming it has not buzzed)?
I'm unclear on why the haptic is a MAJOR safety improvement. If it was a MAJOR improvement in safety, it seems like Shearwater would have added it before now. It's not like the concept of having a vibrating alarm in your dive computer is new.
