Was a absolute steal for $199 so can?t complain about the price it?s hard to beat. Well built all around and comfortable Only con I had was first few uses it felt like it needed a little better air flow. After while it works as intended so don?t be alarmed if it?s not 100% out of the box

Very nice setup, my buddy has this and love's it, I haven't got to use mine yet, but looks great. Really great people to deal with at Leisure pro. Top notch service.

I have used it for years already, down to temperature of 50. They are a workhorse.

Such an amazing reg! Used it for 5 dives in Cozumel and Tulum so far. Very easy to use, respirations easy/unlabored, underwater without audible vibrations. I was able to change my own matching Mares MV octo without a problem. The diving guides were able to change the BC inflator hose and gauge with ease before my diving days started. Assembly onto the tank was effortless. The upgrade to the 15X was a major plus. I'm 1000% happy with this purchase!

Good value for money. I use mine in warm water and have many 100 ft dives with it, no problems at all so far.

after first dive started making whistling noises and vibrating diaphragm noises.

This was a gift for my stepson who is just learning to dive. Looks to be a really nice reg and he loves it.

Really enjoy the sizing and flow of this unit. I have logged over 40 dives and it is just a work horse. I really am enjoying knowing that i have a solid product and that I am just diving instead of worrying about the durability of my gear!

Lightweight and reliability is what the Mares Rover 15X Regulator provides for the diver, with the regulator weighing only 35.45 oz. (1,005 g) with the hose. Reliability does not mean lack of high performance with the combination of the Mares 15X 1'st-stage and the Rover 2'nd stage. The chrome plated marine brass first stage regulator is a balanced diaphragm design which is inherently environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The Instinct 15X uses A.C.T. Advanced Coating Technology. This patented technology created to optimize performance, safety and reliability. 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.
Another unique feature of the first-stage is the dynamic flow control (DFC). The DFC system minimizes the intermediate pressure drop during inhalation. The 15X first stage guarantees a stable flow of air, 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 techno-polymer second stage has superior performance. The patented mesh design of the second stage cover reduces the pressure of water flowing onto the regulators diaphragm and minimizes free-flow. Even in a strong current it eliminates the need for a knob to de-tune your air delivery system- advance technology through basic physics. All Mares second stages are a reliable downstream valve design and offer the unique patented Vortex Assisted Design (VAD) system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.
Mares Rover second stage incorporates the Fluid Dynamic Deflector, developed after in-depth studies and tests of fluid dynamics, 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. Rover 15X has a 3/8" threaded 31.5" (80cm) hose and is Nitrox ready up to 40% oxygen out-of-the-box.
