Scubapro has taken its time-proven Mark 11 balanced diaphragm first stage and teamed it up with a brand new second stage, the R- 195. The R-195 is based on Scubapro’s classic R-190, which enjoyed a well-earned reputation for reliability. The R-195 continues in this tradition, but is built with modern materials and offers additional features. Combining a classic downstream valve with a large diaphragm and center-case purge button, this reg comes with a dive/pre-dive switch that’s shaped and sized for easy grabbing and helps prevent surface free-flows. The reversible hose attachment feature enables you to use the R-195 as a primary second stage or an octo reg, plus is the perfect choice for deco tanks. Bottom line: the Mark 11/R-195 is a workhorse reg set with a solid pedigree, combining dependable breathing with functional versatility.
