This package builds a complete Scubapro regulator setup around the MK11 EVO first stage, paired here with the S270 second stage; C370 second stage and MK11/S270 configurations are also available if you’d rather choose a different combination. The MK11 EVO first stage uses a balanced diaphragm design for consistent airflow across depths and tank pressures, works with Yoke or DIN tank connectors, supports Nitrox mixes up to 40%, and is CE Certified to EN250A for warm, cold, and temperate water diving. The S270 second stage keeps things light with a fiberglass-reinforced nylon casing under a PU outer layer, plus a glove-friendly dive/pre-dive switch for use in the field.
Backing it up is the Scubapro R105 Octopus, a classic downstream-valve second stage with a metal valve housing built for cold-water durability. Its high-visibility yellow faceplate and 39-inch yellow hose make it easy to spot and hand off underwater, and the reversible hose attachment lets you set it up for either hand. Pre-tuned for backup duty, the R105 is meant to breathe smoothly the moment it’s needed, whether you’re diving recreationally or keeping it rigged for sidemount.
The Scubapro Definition Reg 10 Regulator Bag rounds out the package with dedicated storage for both regulators and your dive instruments. A U-shaped opening gives straightforward access, a rain-proof YKK zipper with double sliders keeps contents secure, and a front zippered pocket plus inside mesh pocket hold smaller items. At roughly 32 x 10 x 32 cm and 10 L capacity, it carries by its padded adjustable shoulder strap or top handle, and its external webbing sleeve lets it slide over a roller bag for transit to the boat or dive site.
