SCUBAPRO MK21 First Stage, S560 Second Stage + Added SCUBAPRO Pressure Gauge (Imperial)
AN EXCELLENT MID-RANGE REG SYSTEM
Everything is near-new condition. Used on only 2 dives, always washed immediately with fresh water and stored properly indoors. I am the original owner.
The compact and lightweight MK21/S560 is a full-featured reg combo that's easy to use, offers SCUBAPRO reliability and is priced right, making it the ideal mid-range system for a variety of diving scenarios. Its overall ease of use and reliability also makes it an excellent choice for travel divers. (Retail Price: $719)
-The MK21 is SCUBAPRO's most compact balanced-piston first stage. Smaller and lighter than the MK25, it uses a smaller piston but it delivers the same level of breathing performance, no matter how hard you're breathing, how deep you're diving or what your pressure gauge reads.
-The air balanced S560 second stage features a lightweight techno-polymer casing and comes with full user controls, including an inhalation effort adjustment knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It can be counted on to breathe dry and easy, regardless of depth or your position in the water.
-SCUBAPRO Pressure Gauge (Imperial) installed
Extremely reliable safety necessity. Ultra-compact brass case, offering psi from 0-5000 in 100psi increments. Simple analog gauge is easy to read with a large clear face. No batteries, nothing to charge, no electronic screens to rely on. Fluorescent Dial makes it readable in dark or night dives conditions as well. (Retail Price: $154)

-----TECHNICAL INFORMATION-----
--MK21 First Stage:
• Air-balanced flow-through piston provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Polished chrome plated marine grade brass body is close to 20 percent smaller than the MK25, making it an easy travel companion.
• Two high pressure ports, one on each side of the body, allows the first stage to be positioned either up or down.
• Standard "smart" hose routing cap offers four low pressure ports angled for more convenient hose routing (+/- 20º).
• Redesigned yoke allows for easier mounting on a cylinder, and redesigned cap protects internal components from water intrusion after the dive.
--S560 Second Stage:
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• High flow exhaust valve reduces exhalation effort to lower overall work of breathing.
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
• Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
