About Scubapro Mark 2 Plus Regulator, First Stage Only

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, weighs 24.9 oz (706 g) and is covered by a limited lifetime warranty. Regulator does not include the Low Pressure Hose.

    Comments about Scubapro Mark 2 Plus Regulator, First Stage Only:

    I use this daily. I generally dive over 200 times a year, without and without students. I have had the mark 25 but It seems to need service more often. The mark 2 is very reliable and at the depths I dive, 0 - 130', an unbalanced regulator is fine.
