This complete regulator set pairs Scubapro’s MK25T EVO/S620 X-Ti first and second stage with the R105 Octopus backup regulator and a 3-Gauge In-line Console, so you gear up for cold-water and warm-water diving with one matched setup. The MK25T first stage is machined from titanium for corrosion resistance in saltwater and has two opposing high-pressure ports so it can be mounted up or down to fit your rig. The matching S620 X-Ti second stage uses a titanium inlet tube and XTIS thermal insulation to protect its inner components and reduce ice formation in cold water, backed by an air-balanced flow-through piston for steady airflow regardless of depth or tank pressure.
The R105 Octopus rides along as your backup, built around a classic downstream valve and a rugged metal valve housing for durability and cold-water performance. Its 39-inch hose is reversible for left- or right-hand setups, and the high-visibility yellow faceplate and hose make it easy to spot and hand off underwater. The 3-Gauge In-line Console rounds out the set with a fluorescent-dial pressure gauge reading 0-6000 psi / 0-400 bar, an oil-filled depth gauge with a linear Bourdon tube movement, and an FS-1.5 compass with a 26-degree tilt for steady readings, all in a compact inline housing.
Choose DIN or INT connection type to match your tank valve when you order. Regulator, octopus, and console ship together as one coordinated Scubapro setup, so first stage, second stage, backup air, and instrumentation are covered in a single purchase.
