SCUBAPRO has teamed its Mark 11 balanced diaphragm first stage with a new second stage, the R-195. Combining a classic downstream valve with a large diaphragm and a center-case purge button, the R-195 comes with a large dive/pre-dive switch that helps prevent surface free-flows. The reversible hose attachment feature lets you use the R-195 as a primary second stage, an octo reg, or the perfect choice for deco tanks.

In 2012, ScubaLab tested new and redesigned fins and these four models were this year's top guns.
