Mares Ultra Adj 82X Regulator

416250 - Ultra Adj 82X

Mares’ Ultra family of regulators is aimed at meeting the needs of the most demanding divers, at a competitive price.

The Ultra’s excellent second stage is constructed in ultralight, ultra-resistant technopolymer. A result of continuous research and innovation; a characteristic that Mares is known for.

Vortex Assisted Design (VAD) allows for unobstructed airflow and consistent natural breathing at any depth.

The innovative Twin Power System offers further adjustment, allowing the diver to control the rate of airflow. A simple turn increases airflow on demand; designed for a diver working hard or making very deep dives.

The excellent Ultra ADJ second stage is pneumatically balanced with the Pneumatically Assisted Design (PAD) system, offering effortless and comfortable breathing in every situation.

Divers will also appreciate the option to fine-tune cracking effort (initial effort to start the flow of air) by simply turning an adjustment knob. Designed to be easily manipulated, even if wearing thick gloves.

The combination of PAD and Twin Power systems, paired with the option to adjust cracking effort, provides the best performance with the most comfort, under all conditions and at any depth.

The 82X boasts a swivel turret with five low-pressure ports - 4 radial and 1 vertical - to meet the needs of all, including advanced or technical divers. All LP ports offer Mares’ patented Dynamic Flow Control (DFC) for elevated and consistent airflow, at all depths.

O.P.D. (Optimized Port Design) is yet another unique feature of this first stage. Two pre-oriented high-pressure ports are angled opposite each other, allowing the diver to use a pressure gauge and/or computer transmitter at the same time. Additionally, the first stage can be positioned with the swivel turret facing up or down, providing maximum freedom of choice.

The 82X first stage is also equipped with Mares' Auto-Sealing Technology (AST) system, providing excellent protection against the intrusion of water or unwanted matter. A very simple mechanical solution keeps the internal mechanism dry and free of obstruction, consequently providing superior reliability.

Available in INT and DIN versions.

The Ultra ADJ 82X encapsulates a top of the line regulator for serious divers seeking only the best in quality, technology and performance - let’s discover more about Mares’ incredible tech features incorporated in to its design!

In nature, every time a fluid moves in a ‘vortex’, for example in the case of air, like a tornado, or in the case of water, in whirlpools which sometimes form in rivers, at the center of the phenomenon an area of depression is created. Mares regulators use this same phenomenon, sending airflow, via a special bypass, directly into the mouthpiece of the second stage using a rotating movement, a ‘vortex’, which creates a depression within the second stage during inhalation. This depression aids the lowering of the diaphragm, reduces breathing effort and, as a consequence, makes breathing noticeably more comfortable.

This ingenious solution, compared to the so-called “Venturi effect” on which all other regulators are based, allows for better breathing in all diving conditions. In fact, in regulators using the “Venturi effect”, the airflow is directed straight towards the mouth, often creating an unpleasant feeling of ‘injected air’. In Mares regulators, however, thanks to the VAD system, divers breathe easier, but above all more ‘fully’ and more naturally, even at depth.

VAD technology also proves superior when used in cold waters, as, thanks to this characteristic rotating air, there is a minor drop in the temperature of the second stage which, as a consequence, considerably reduces the possibility of free flow, which represents one of the most common risks in such diving conditions.

Many of Mares’ regulator models with VAD second stages have been approved and used by navy and military corps, including the US Navy, even for dives in extremely cold waters.

The VAD system, whilst maintaining its exclusive operational characteristics, has seen continuous improvements over the years, with a constant study of airflow both using test machines and on dives, which have led to optimum shaping of the bypass tube, as with the Ultra second stage which includes a “doubled-curved” bypass.

PAD

The abbreviation PAD stands for ‘Pneumatically Assisted Design’. With this system the diver has a “assisted-supply” second stage. Within the second stage there is an area of “partial compensation” of intermediate pressure, in fact, coming from the first stage, which allows the use of a much softer spring as a consequence and greater breathing comfort as an advantage.

The combination of Twin Power, ADJ and PAD systems, as found in the Ultra ADJ 82X, offers divers maximum performance, maximum possibility of personalisation and maximum comfort, in all diving conditions and at all depths.

This infiltration can damage the inside of the regulator, the hose and the instruments that may be connected to it, sometimes seriously. Furthermore, it can also cause contamination from bacteria, with possible health risks, or decrease the airflow of the regulator, with a consequent decrease in performance.

Unlike other systems available on the market, always aimed at avoiding possible infiltration, the AST system from Mares does not use springs or other metallic components, but is made only of pieces in technopolymer and elastomer which, as well as avoiding the formation of oxidation, rust and limescale, also have excellent mechanical characteristics, which guarantee great resistance to wear and abrasion.

The activation of the AST system is pneumatic. During the inhalation phase, meaning when there is a request for air, the internal part in elastomer expands slightly, allowing for the flow of air, whilst it closes during the exhalation phase.

This simple yet clever solution guarantees a flow of air without limitations. The drop in high pressure from the tank is, in fact, inferior to 0.5 bar, that is completely insignificant and definitely inferior to that of other anti-infiltration systems, so much so, for example, that Mares regulators equipped with the AST system greatly exceed not only European norms EN 250, but even the very strict Norwegian Norsok U-101 norms, to a depth of 400 meters!

The AST system can also be used for dives in very cold waters and with Nitrox mixtures.
