Mares Regulators — Smooth Breathing, Built on Patented Airflow Engineering
A regulator's job sounds simple — deliver air on demand — but the engineering behind making that delivery effortless at any depth, in any temperature, is where Mares has invested decades of development. The result is a lineup built around two complementary patented technologies: VAD (Vortex Assisted Design), which creates a swirling airflow pattern that directs air toward the mouthpiece to reduce inhalation effort, and PAD (Pneumatically Assisted Design), which adds pneumatic assistance for high airflow even in extreme cold or demanding depths.
At DiveCatalog.com, we carry the current Mares regulator lineup — first stages, second stages, complete sets, and octopuses — as an authorized dealer.
The Mares Regulator Range
First Stages — 15X, 62X, 82X
The 15X is Mares' accessible entry first stage — a balanced diaphragm design in lightweight Ultralight Technopolymer construction, suited to entry-level and training scenarios. The 62X is genuinely remarkable engineering: at 63mm and 464g (DIN), it's the smallest first stage on the scuba market, 10% smaller and lighter than its 52X predecessor with 30% less internal volume, while still delivering Auto Sealing for smooth airflow across diving environments. The 82X steps up further with a 360° rotating turret and Dynamic Flow Control (DFC) for maximum airflow, aimed at recreational and technical divers who want the most capable first stage in the lineup.
Second Stages — Dual ADJ, Ultra ADJ
Mares second stages use the VAD/PAD combination to deliver smooth, low-effort breathing. The Dual ADJ 62X pairs the compact first stage with a pneumatically balanced second stage featuring Dual Adj control, while the Ultra ADJ 82X brings the Dynamic Flow Control system to the second stage as well for divers who want maximum tunability across depth and exertion levels.
Octopuses — Atlas, Ultra, SXS, Rover
The Atlas ADJ is an all-metal octopus with high thermo-conductivity, purpose-built for cold-water diving where the lack of moving parts inside the bypass prevents ice crystal formation. The Ultra and Ultra ADJ octopuses use lightweight, resistant technopolymer construction with Mares' Twin Power System, letting divers adjust airflow speed for harder-working or deeper dives. The SXS (Second eXtra Small) is built for extreme compactness and can mount on either the right or left side. The Rover octopus is the rental-fleet workhorse — rated to over 113,000 venting cycles with a dynamic-hinge vent button designed to resist free-flow in strong currents.
Understanding VAD and PAD
VAD (Vortex Assisted Design) creates a controlled swirling motion of air inside the second stage as you inhale, directing the flow toward the mouthpiece rather than relying purely on demand-valve mechanics. The practical effect is reduced breathing resistance and a more natural feeling inhale, particularly noticeable at depth where standard regulators can start to feel like work.
PAD (Pneumatically Assisted Design) works alongside VAD in Mares' higher-tier regulators, using a pneumatic boost to maintain high, smooth airflow even in cold water or at extreme depths where standard mechanical designs can struggle. Combined, VAD and PAD are why Mares' premium regulators are rated for genuinely demanding cold-water and technical diving conditions, not just fair-weather recreational use.

Frequently Asked Questions — Mares Regulators
What makes the 62X first stage special?
It's the smallest first stage in the scuba market at 63mm and 464g (DIN configuration) — 10% smaller and lighter than its predecessor with 30% less internal volume, without sacrificing the Auto Sealing performance that maintains smooth airflow.
What is the difference between VAD and PAD?
VAD (Vortex Assisted Design) creates a swirling airflow pattern that directs air toward the mouthpiece, reducing breathing resistance through fluid dynamics. PAD (Pneumatically Assisted Design) adds pneumatic boost to maintain airflow in cold or extreme conditions. Mares' higher-tier regulators combine both for maximum breathing comfort across the widest range of conditions.
Why choose an all-metal octopus like the Atlas ADJ for cold water?
All-metal construction conducts heat more effectively than technopolymer, and the absence of moving parts inside the bypass prevents the ice crystal formation that can cause free-flow or regulator failure in genuinely cold water.
Is the Rover octopus suitable for personal ownership, or just rental fleets?
While it's specifically engineered and tested for rental-fleet durability, the Rover's rugged construction and proven reliability make it a perfectly capable personal octopus for any diver who values toughness and field-proven performance.
