Let’s preface this by saying I’ve been diving Shearwater computers for over 13 years, and I don’t think there are better dive computers.
The new Perdix 2 has 3 new dive modes that makes me scratch my head, “Air mode”, “Nitrox single gas” and “Nitrox 3 gas”, this is the sort of thing we see on just about any dive computer manufacturer out there, I’d call these recreational “wanna be” technical dive computers, they’re just regular computers with 3 gas capability but sucks at decompression diving.
I thought the industry was done with this “Air mode” thing too, pretty much everyone just understood that leaving the mix at 21% is “Air mode”, but then here comes Shearwater with it.
This being present anywhere else I wouldn’t question it, but if Shearwater does it, makes me pause to think, have I not understood this whole thing? It’s like when they started supplying surgical tubing for straps for their computers, I understood bungee cord to be far superior than surgical tubing, but if shearwater was sending out their computers with surgical tubing, I went, woah, what do they know about them that I don’t? Why not supply the computers with bungee? I mean, it’s shearwater, they know what they’re doing, right? It’s not engineers with little dive experience producing subpar dive gear pushed to the market by the marteking department of a large corporation manufacturer.
But it isn’t, bungee is far superior than surgical tubing.
So, to the dive modes, I’ve typed way more than I like too already, let me ask just the “Nitrox 3 gas” mode for now, I’m having a hard time understanding the real use of such a mode, it’s for recreational diving, aka, no deco. But let’s not be too strict, some recreational divers do go into deco, they call it “light deco” dives, or something like that. And that is deco done on back gas.
So, say such a diver now decided that the “light deco” they do warrants bringing a 2nd gas mix to accelerate the decompression, I mean, I get to this point in typing this and I’m already finding a hard time continuing and not describe a tech dive.
And the mode is designed to allow 3 gasses, in what agency/training are divers trained to use 3 gasses in which it doesn’t fall into the tech diving realm?
Even on the tech dive training, how many agencies/courses start students with 2 gas switches right at the entry level?
And what agency/training gives RECREATIONAL divers access to mixes higher than 40%? This question is also important when consider a dive requiring 3 gasses, which none are higher than 40% O2
So, please educate me and help me understand the real practical application of such a mode. In doing so, please provide an example dive with the depth, time and gases, that doesn’t fall into the tech diving category of course. And if managed to do so, please also contrast that with just using the “OC Tec” mode.
What’s next, future versions gonna lock divers out too?
