This Scubapro regulator package bundles a complete breathing setup: a first and second stage regulator, the R105 octopus as your backup, and the Definition Reg 10 bag to carry it all. Choose the regulator that fits how you dive: MK2 EVO/S270, MK11/S270, or MK11 EVO/R105. The MK2 EVO/S270 pairs a piston first stage with the compact S270 second stage, with a balanced 2nd stage design that reduces inhalation effort. The piston first stage has a chrome-plated brass body with 1 high-pressure port and 4 low-pressure ports, supports Nitrox mixes up to 40%, and uses a DIN connector. XTIS extends thermal insulation for better cold-water resistance, and at roughly 3.1 lb it’s built for comfortable handling with gloves.
The R105 octopus is your backup regulator, built with a classic downstream valve design and an adjustable second stage that’s pre-tuned for smooth, effortless breathing when you need it. Its metal valve housing holds up in cold water, and the high-visibility yellow faceplate with 39-inch yellow hose makes it easy to spot and reach in an emergency. The hose attachment is reversible for left- or right-hand setups, and at 0.8 lb it stays light enough for travel or sidemount use.
The Definition Reg 10 Regulator Bag keeps the whole setup organized and protected between dives. Its U-shaped opening gives easy access, a rain-proof YKK zipper with double sliders keeps contents secure, and a front zippered pocket plus inside mesh pocket hold small items. With a 10 L capacity, an adjustable removable shoulder strap, and an external webbing sleeve that slides over a roller bag handle, it moves from the car to the boat to the dive site without a second bag.
