Whats in the box:1st Stage, 2nd Stage, LP Hose MK2 Plus First Stage
This first stage epitomizes reliability and s implicity. Its standard 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 p eace of mind that comes with a sound piece of equipment. This first stage is equ ipped with SCUBAPRO's Thermal Insulating System (TIS), which will keep your firs t stage functioning properly,even in frigid water. The MK2 has one high-pressure port and four low-pressure ports. R295 Second Stage
This second stage offers an ideal balance of quality, comfort, and reliability. The R295's downstream valve means you can dive breathing easily - both literally and figuratively. The R295's streamline design, minimal weight, and orthodontic silicone mouthpiece mean jaw fatigue and pain will be a thing of the past. Its streamline shape also means that drag is practically a thing of the past. Just as important as the R295's smooth diaphragm action is SCUBAPRO's guarantee of unsurpassed quality and workmanship.
This VIVA-patented system 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.
