Welcome to Dive Gear Reviews, a comprehensive guide to scuba diving equipment. Scuba diving is an expensive pursuit, so looking up reviews for a particular article of equipment is a wise precaution before investing any hard-earned money in it. However, consumer reviews may or may not be written by an experienced diver, and magazine reviews could be suspect due to the advertising ties of the publication in question. Dive Gear Reviews provides cross-referenced reviews assembled by an expert, making it possible to see at a glance what multiple sources said about a particular piece of scuba equipment. If one magazine loved a scuba regulator or a dive computer, but the consumers hated it, that information will be found here.

Scubapro Mk21/S560 Scuba Regulator Review

Written by Dive Gear Reviews Editor. Comments Off on Scubapro Mk21/S560 Scuba Regulator Review Posted in: Over $500, Scuba Regulators

Understanding Scubapro regulators means seeing them as paired units, rather than complete articles. This particular unit combines the Mk. 21 first stage and the S560 second stage. Although paired as a set, both halves are available separately and can be combined with other Scubapro parts. Many divers upgrade their Scubapro regulator systems by taking an old first stage and replacing the second stage or visa versa.

The Mk21/S560 combination is Scubapro’s major mid-range regulator system. The balanced Mk21 uses a smaller piston than th Mk25, but delivers the same performance. So, it’s smaller and lighter, but holds the line on quality. An added plus are the chrome fins on the body, giving the regulator better thermal regulation. That helps guard against freezing in cold water.

The S560 is a balanced mouthpiece with an inhalation control knob and a Venturi, on-off switch. The first adjusts air flow, and the second is the safety against free-flow accidents. Finally, the polymer casing keeps the weight down to just 6 ounces (172 g).

The Scubapro Mk21/S560 is compact and lightweight enough to count as a travel system, making it an ideal example of a piece of scuba equipment that bridges the gap between home area and vacation diving equipment. It was a 2014 Best Buy choice for Scuba Diving, and a 2015 Editor’s Pick at Sport Diver.
