ProVari is the only thing I own that will downregulate well for my preferred setup.
Fixed that for ya.

As far as I know, just about every regulated device starts around a down-regulated 3V as the lowest setting of it's adjustable range. The exception to this is the newer DNA and SX variety. Now whether or not the old cheap-o 33.3Hz devices will do this as well as a Provari, and what the lowest resistance any device will fire to, is another story, but there you have it.
Is why I sold my DNA's and Semovar. I like my Russian at .8 oms with 26 gauge Kanthal, around 3 volts.
Well, that's good you like it set there, because that's absolutely the only setting where you can vape that coil on a Provari.
2.9V, aka the very lowest setting on the Provari, is the
one and only setting on a Provari that will fire a .85Ω coil without exceeding it's 3.5A limit. Any adjustment above that will shoot you an error. Obviously, you cannot adjust down from the 2.9V setting.
Also, and this is totally anecdotal; if people think sub-ohming is a super small niche of the vaping scene, I'd imagine under-powering sub-ohm coils is a downright microscopic niche.
None of the others will actually deliver that (unless the battery is low.
Crank a Kick 2 to 10W and you have the exact same down-regulated vape on your .85Ω coil, and as a bonus, you can now even adjust lower or higher from there.
I'm not saying your Russian with a .85Ω coil at around 3V isn't a great vape to you, and that you aren't in a super happy place with your setup; just pointing out some mis-information posted that maybe/apparently you have come to think of as fact when it comes to numbers and such. On the plus side, even though you can't adjust a damn thing voltage wise with your .85Ω Russian setup, it is at least
consistently regulated at that 2.9V... so that's cool I guess.
