Classic downstream piston- The Mark 2 Plus is the best example of bulletproof reliability and trouble-free, minimum maintenance regulators. The classic downstream piston configuration is the simplest mechanism that exists to control the pressure drop from a tank to feed the second stage. The classic downstream valve is the first choice of diving centers and rental facilities worldwide for warm and moderate water temperatures. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming air flow. To close the valve and stop the air flow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.

This first stage epitomizes reliability and simplicity. Its standard Flow-By Piston design is ideal for divers who don't want to get bogged down with an overwhelming amount of bits and pieces, but still want the peace of mind that comes with a sound piece of equipment. This first stage is equipped with SCUBAPRO's Thermal Insulating System (TIS), which will keep your first stage functioning properly, even in frigid water. The MK2 has one high-pressure port and four low-pressure ports. The first stage body is manufactured from marine-grade chrome plated brass.

The R195 is a new design based on the heritage of the classic R190 second stage, re-engineered with modern features and materials. The R195 combines a classic downstream valve with a large diaphragm and classic purge button. It's simple and robust construction with a Techno-Polimer Valve Housing offers the utmost in reliability and makes the R195 the ideal second stage for new divers and a perfect choice for deco tanks thanks to its reversible hose attachment. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming airflow. To close the valve and stop the airflow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve. The classic downstream valve is featured in the SCUBAPRO R-Series; here "R" is synonymous with robust and reliable.

The R195 Second Stage has SCUBAPRO's Venturi Initiated Vacuum Assist (VIVA-patented system. The VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver-adjustable on all current SCUBAPRO second stages. The MK2-Plus/R195 Regulator weighs 36.9 oz (904 g), comes with a 3/8" Threaded Low Pressure Hose, Owner's Manual and is covered by a Limited Lifetime Warranty.
