82X First Stage.
The 82X first stage is forged from brass, chromium-plated and finished with a pearly surface. This processing makes it highly resistant to abrasion, while providing a unique and elegant appearance. It features a balanced membrane diaphragm designed to ensure advanced and reliable performance at any depth.
The 82X features a rotating turret with five low pressure ports (4 radial and 1 vertical) to meet the needs of everyone, including experienced or technical divers. All LP ports offer Mares' patented Dynamic Flow Control (DFC) for high and consistent airflow at all depths.
O.P.D. (Optimized Port Design): Another unique feature of this first stage is two pre-oriented high pressure (HP) ports, angled opposite each other. The first stage can be positioned with the rotating turret facing up or down for maximum freedom of choice.
The 82X first stage is equipped with Mares Auto-Sealing Technology (AST), which provides excellent protection against the intrusion of water or unwanted substances. A very simple mechanical solution keeps the inside mechanism dry and free from obstructions, thus providing superior reliability.
The 82X is available in INT and DIN versions.

Ultra Adj Second Stage.
The Ultra Adj second stage is constructed from a new ultra-lightweight and ultra-strong technopolymer. The Vortex Assisted Design (VAD) allows unimpeded airflow and constant natural breathing at any depth. The innovative Twin Power System offers further adjustment, allowing the diver to control the speed of airflow. A simple twist increases airflow when required; designed for the very deep diver. The second stage Ultra Adj is pneumatically balanced with the PAD (Pneumatic Assisted Design) system, offering comfortable and effortless breathing in every situation.
The combination of the PAD and the Twin Power systems, coupled with the ability to adjust the breathing effort, provides the best performance with maximum comfort in all conditions at any depth.
A Superflex hose connects the first stage to the second stage and provides support and flexibility for comfortable diving.
Also available as an Octopus with the same features.
Meets and exceeds the requirements of the Norsok U-101 standard to a depth of 200 m.
