"HP / LP ports" is the number of high-pressure and low-pressure ports on the first stage, which caps how many accessories (transmitter, SPG, inflator, second second-stage) you can run at once.

Pros
  • 82X first stage puts 5 low-pressure ports on a 360-degree rotating turret, more routing flexibility than the smaller 62X-based regs
  • Twin Power System second stage lets you switch between relaxed natural breathing and boosted airflow, and at 192g it's far lighter than the all-metal Atlas/Epic second stages
  • Auto Sealing Technology keeps the first stage dry without a separate cold-water upcharge
Cons
  • Technopolymer second stage doesn't have the thermal mass of the all-metal Atlas ADJ 62X, worth weighing for serious cold-water use
  • Costs more than the smaller Ultra 62X for the bigger first stage and extra LP port
  • Too new in this catalog to have accumulated dedicated diver discussion yet, treat as an emerging track record

The Ultra ADJ 82X pairs Mares’s current flagship 82X first stage, a sealed, balanced diaphragm design with a five-port rotating turret, with a lightweight technopolymer second stage carrying the adjustable Twin Power System. It effectively replaces the Epic ADJ 82X as Mares’s top-tier adjustable diaphragm reg, trading some of the Epic’s all-metal heft for a lighter, more travel-friendly package.
