REGULATOR Scubapro S600/MK25 Classic

Isnt this where we came in
Remember, remember, the fifth of November. I remember 5 November 1983. It was my first trip to dive in a flooded slate quarry in Leicestershire.
I went to try out my shiny new rubber Viking drysuit. Until that day I had always dived in limpid, clear, blue water. What a daunting prospect that Stoney Coves grey lake made.
 My regulator was a Spirosub. It had all the outward design appeal of a tin of baccy - Three Nuns on the end of a hose.
 It didnt give me much air, but I never expected much. However, what it also didnt do was go into an uncontrollable free-flow because it froze. Those days were yet to come.
 During the next decade, the folks at Stoney Cove would regularly see divers disappearing in a cloud of bubbles before climbing out mouthing curses about their kit.
 Before that, regulators had given air-flows that were puny enough to make those trying to breathe from them feel like asthmatics. So manufacturers addressed the problem and increased their regulator performance to something approaching todays acceptably high levels.
 However, at about the same time, they also adopted lightweight technopolymers in the construction of second stages. This meant less weight on the mouthpiece and far more diver comfort. Great for the majority of divers who spent their time in the Caribbean, Red Sea or Indian Ocean, but not so good for that small minority, worldwide, who spent their weekends diving in cold, fresh water.
 Delivery of vast quantities of depressurised air in conditions close to freezing was asking for trouble. Many of us got that trouble, because the technopolymers used had a low coefficient of conduction. In an attempt to warm the air, some manufacturers tried adding bits of metal as heat sinks.
 Bring back the baccy tin! That never froze. There is no substitute for metal in coldwater designs, as many regulator manufacturers have now realised.
 Some have abandoned plastic in the quest for safe low-temperature use. Its a classic solution to a modern problem.
 The Scubapro S600/MK25 regulator is close to the acme of that manufacturers achievements. It can deliver exceedingly high quantities of air with a low work-of-breathing .
 Recent modifications to the first stage have been designed to further reduce the problem of icing. Now Scubapro has gone all the way - all the way back to where we came in because, reminiscent of the old classic Scubapro MkV and MkX, the new Scubapro S600/MK25 Classic has a chrome-plated brass front to its second stage!
The Scubapro S600/MK25 Classic costs £399.
