Product Overview

With advanced performance and reliability, the Mares Prestige 15X Regulator is a compact primary regulator at an incredible price point.  Loaded with Mares’ high end features, this regulator meets all the diver’s demands at any depth.

The first stage of the Mares Prestige 15X Regulator is built with chrome plated marine brass.  It is both balanced and environmentally sealed, preventing water and contaminants from entering.  A diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for water to enter.  Utilizing A.C.T. (Advanced Coating Technology), performance, safety and reliability are optimized.  The valve is covered with a hard Polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty" PU) reaches new levels of durability. The new valve is 600% more durable than its predecessor.

Featuring the DFC system, the intermediate pressure is minimized during inhalation, allowing the Prestige 15X to provide stable air flow even under extreme conditions.  The First Stage is equipped with 4 LP ports with 3/8" and 2 HP 7/16" ports for attachment of a Pressure Gauge or Air Integrated Console.

The Prestige 15X includes a medium-size second stage made of ultralight techno-polymer. The large purge button is effortless to use while wearing gloves. The VAD system delivers excellent and natural breathing at any depth.  In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.  Mares’ Mesh Grid is a patented design which reduces the impact of water flow onto the second stage diaphragm, eliminating free flows even in strong currents.

The Mares Prestige 15X second stage incorporates the Fluid Dynamic Deflector, which is engineered to receive and properly direct the airflow from the bypass tube to the mouthpiece. Combined with the VAD system it delivers very natural and effortless breathing.
Included with the Prestige 15X is a superflex hose which is light and flexible for maximum comfort. The super flex hose has 3/8" threads and is 31.5" (80cm) in length. The regulator weighs 34 oz. (965 g).  The Mares Prestige 15X is nitrox compatible up to 40% oxygen (EAN40) out of the box.

This product can only be shipped to U.S. addresses.

Perfect for recreational diving

Used this on three dives on a recent trip to Anacapa Island in Souther California. I am very happy with the regulator - comfortable mouthpiece, light weight, very easy to breathe on various depths and orientations (horizontal, upside down, overturn, etc.), no problem at all, routes air to the side of your face/mask nicely so you have a very clear view. Unbeatable price from (with a small discount). Highly recommended.
