The Abyss 22 Navy II is Mares’s cold-water and technical flagship, a fully sealed, all-metal balanced-diaphragm regulator built for ice diving, drysuit divers, and anyone diving in genuinely cold conditions where a sealed first stage matters. It’s not the reg for someone counting grams on a warm-water trip, but for cold water it’s one of the more rigorously tested options in Mares’s lineup. Also sold in an INT/yoke configuration.
