Scubapro’s Mark 25/S-600 has been restyled for 2013 and is now available in four versions. Each model offers its own unique
cosmetics, coatings, and construction materials, but they all have one thing in common—awesome performance. In ScubaLab
breathing machine tests the Mark 25/S-600 has consistently outpaced all regulators, past and present, in sheer muscle reg performance. And in the ocean it breathes like a dream.
