Scuba Diving Regulator + Pressure Gauge Combo - SCUBAPRO MK21/S560

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) -Low Pressure Inflator (LPI) / Alternate Air Source hose -----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. ******************************************** 𝗧𝗢𝗧𝗔𝗟 𝗖𝗢𝗠𝗕𝗜𝗡𝗘𝗗 𝗥𝗘𝗧𝗔𝗜𝗟 𝗣𝗥𝗜𝗖𝗘: $𝟴𝟳𝟯.𝟬𝟬 ********************************************
