SCUBAPRO's most compact, high performance piston first stage teams with its most compact, high performance second stage. The result: a top-drawer, travel-friendly reg system that delivers reliable airflow on demand, no matter where your dive travels take you.
The MK21 is SCUBAPRO's first balanced-piston first stage to be released since the introduction of the MK25. It is smaller and lighter than the MK25 and uses a smaller piston, but it delivers the same level of breathing performance. The MK21 also provides exceptional resistance to freezing due to the thermal exchange produced by the external fins on its polished chrome brass body. The MK21's innovative "smart" hose layout comes with a standard cap with four low pressure ports angled (+/- 20º) to maximize hose routing. This standard cap can be replaced with an optional cap that offers four low pressure ports at more extreme angles (0°/30°) plus a fifth centralized high-flow low pressure port - a useful configuration for technical diving.
The C350 is the most compact second stage in SCUBAPRO's line, so takes up little space when traveling. It is lightweight, breathes smooth and extremely easy, and offers a coaxial-flow inhalation effort control knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. The stainless steel front cover frame adds a bit of style.
The MK21/C350's size, weight and excellent breathing performance make it a smart choice for recreational divers in general, and just the ticket for dive travelers in particular.
