R390 Second Stage $170
(first stage and computer sold separately)
The R390 regulator's classic design and downstream valve second stages are ideal for sport divers and diving programs. The downstream valve technology used in the R390 has been perfected by SCUBAPRO and has proven itself to be reliable and convenient to use. Another feature of the R390 is the user-controlled Venturi Initiated Vacuum Assistant (VIVA). The VIVA system reduces the amount of effort divers expend when breathing; this patented technology is user-managed and is available on all current SCUBAPRO second stages. The R390 combines a time-tested, fourth-generation downstream design with rugged construction and dependability.
