This month, you get to find out about my lazy side. When it comes to my regulator, I want to feel its presence as little as possible during a dive. When I need a breath of air, I want it to be as effortless as breathing on land. And when I carry it from destination to destination, I want it to weigh as little as possible. Oh, and I'm not usually too coddling with my gear, so I need to be able to stand up to a fair bit of abuse.
Between trips, my regulator of choice, the SCUBAPRO MK25T/S600T , usually just sits in my dive bag. No special treatment. No hallowed place on a shelf or hanging on the wall. When I pack for a trip, I simply check that it's still there, solid in my knowledge that when I arrive at my destination, it'll be the last piece of equipment I need to worry about.
There's a lot of cool technical stuff about this reg, too. The first stage has a solid titanium body, yoke and components. That means when cockroaches finally die off on this planet, this first stage will still be ready to go. And titanium is not only strong, it's light, which fulfills my lazy requirement nicely. It also utilizes a patented overbalanced piston that's a mix of composite and stainless-steel material. And the intermediate pressure can be externally adjusted, which means that you get optimum airflow through the MK25T's five low-pressure swivel ports and two high-pressure ports.
Air is an important component of the breathe-in, breath-out requirements of diving, which takes us to the S600T second stage. I've adjusted the cracking pressure on this second stage so that it requires so little effort, I hardly notice the exertion of inhalation. No need to waste energy trying to suck air from the tank, and it provides me with this effortless supply of air regardless of my depth. The S600T is also lightweight and compact, which I've been thankful for while facing down the strong currents you find in Coco, Fiji and the Tuamotus. And during all this, the mouthpiece keeps the reg firmly in place without undue effort that could lead to jaw fatigue. There's also a diver-adjustable venturi assist, which honestly I've never touched since it came out of the box. I leave it wide-open, where the breathing is easy, and don't mess with it. The purge valve has a light touch, even with thick gloves. The whole thing is made from a tough-as-nails technopolymer material, which, thankfully, not only holds up to my rough treatment but also repels any of the odd assortment of smells that permanently reside in my dive bag.
