I think it’s Vinzant. The setup works and breathes alright, but the placement of the suit inflation bottle on the left side + the optimal setup of the canisters means that there’s a high sensitivity to how much gas is in the wing. 8” cylinders like those worn in the video set the center of the inflation (or oxygen, if not butt mounted) higher away from the scrubbers and thus allow for some gas in the wing. The same placement on small cylinders is a little more difficult and doesn’t leave much room for the wing to inflate (and needs to be correct wing size).
Boat diving in a wetsuit without suit gas and a pair of doubled AL40s with a couple others of deco bottles? Super slick. Once you start adding things on top of it or move towards bigger cylinders, you’re much better off with a rack or a traditional 3L setup on a rebreather. If it’s a couple times a year thing and you only want to own one unit and can’t handle the SW on a moving boat, it’s good enough. Can’t really recommend it without hesitation though.
