What's in the box: SCUBAPRO MK21 Regulator, First Stage Only, DIN

The SCUBAPRO MK21 is a new Compact-Sized Piston-Controlled First Stage. Close to 20%-Smaller than SCUBAPRO's MK25, MK21 is a Mid-Range Air Balanced, First Stage. Air Balanced Pistons deliver Significantly-More Air to the Second Stage than any other First Stage, while their performance is totally unaffected by the changing tank pressure. A Balanced Piston allows the use of Lighter-and-More-Sensitive Components, resulting in Ultra-Fast Breathing Response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced Piston First Stages are the first choice of demanding sport divers and professionals. A Balanced Piston performs equally in warm and cold water environments.

The MK21 First Stage offers the best compromise for the right price and the right performance with Ease-of-Maintenance. Cold Water Diving with SCUBAPRO-Diving conditions can be drastically different, including extreme cold water and outside temperatures, posing the possibility of a regulator "freezing". Therefore, Resistance-to-Freezing is Imperative for the diver. All SCUBAPRO Regulator Systems are CE Approved for 4300psi (300 bars) Cold Water Diving. Some models go even beyond this Super-Stringent-Qualification and have successfully been Tested-in-Extreme-Cold-Diving-Conditions at less than 39°F (3.9°C). As a Specific-Anti-Freezing-Measure, SCUBAPRO engineers have designed a Patented Finned Cap for the MK21 First Stages for Optimal-Cold-Water-Diving. This Finned Cap is a Thermal Insulating System (TIS).The Ribs of the TIS Act-as-a-Radiator to Increase the Surface-Area of Heat-Transfer from the Water to Warm-Up the Internal-Parts that have been Drastically-Cooled-Down by the Gas-Pressure-Drop.

The MK21 is manufactured from Marine-Grade Chrome Plated Brass, has a Balanced Composite/Stainless Steel Flow-Thru Piston and with the Standard Head it has 4-HF (High Flow) Low Pressure (LP) Ports with Hose Routing at +/- 20° Degree Angles and 2 High Pressure (HP) Ports, one on each side of the body. The MK21 First Stage weighs 19.6oz (555g) with externally adjustable intermediate pressure which allows authorized SCUBAPRO service technicians to quickly fine-tune and adjusts the first stage after maintenance without the need to disassemble it. The First Stage is covered by a Limited Lifetime Warranty.
