Mares Proton 42 Scuba Regulator

0

As a PADI dive master, my students frequently ask me about what kinds of equipment to purchase. The most inquired after equipment is the regulator. If you’re an avid diver, a regulator would probably be the most vital item of your scuba gear. After using several different kinds of regulators, I often recommend the Mares Proton 42.

When scouting for a regulator to purchase, I always ensure that it is not unbalanced. A well balanced regulator allows underwater breathing to come naturally, regardless of the depth of one’s dive. Unbalanced regulators are more difficult to use in low pressures. The Mares Proton 42 is balanced so it received a tick on my checklist. Additionally, some people ask me which is better – a piston regulator or a diaphragm regulator.

Personally I prefer a diaphragm regulator because it’s sealed from the environment and it corrodes less than a piston regulator, however because a diaphragm regulator is made of more parts, there is a greater chance of something going wrong in comparison to the piston regulator. The Mares Proton 42 is a diaphragm regulator but you would have already known that because a diaphragm regulator will always be a balanced regulator. Still on the topic of diaphragms, the Mares 42 Proton Metal Regulator uses the DFC system and a replaceable HP seat connector. So like any good regulator, this feature allows for the reduction of breathing effort and inhalation resistance, especially when taking a deep dive.

I also like the fact that the Mares Proton 42 first stage (connected at the top of the scuba tank) is made from hot-forged nickel plating and chromebrass while the second stage or demand valve (mouthpiece that blows bubbles) is made out of nickel and chrome-plated brass. This allows for ruggedness and thinner walls and reduces water drag. The second stage also has an anti-freeze function because the metal acts as a radiator. By the way the mouthpiece is made out of soft hypoallergenic silicone so after using the Mares Proton 42 I don’t feel like I’ve been chewing rubber like the discomfort I get around my jaw with other regulators.

I won’t go into hose routing as I might say something to spark vehement debate from adamant arguers of breathing long hose or breathing short hose. What I will say is that the Mares Proton 42 also has HP and LP ports that are set for optimum hose routing, whatever your preference.

I had hoped that the Mares Proton 42 was designed to handle a high oxygen concentration without fear of combusting, but no one has assured me of that, neither do any of its reviews and descriptions on the web. Nevertheless – so far so good. There is no ‘one fits all’ regulator. It all comes down to preference and what you can afford. Remember safety comes first, so look for a quality regulator with a good warranty.
