Scubapro G260 MK25 EVO with R105 Octopus

Scubapro G260 MK25 EVO with R105 Octopus combines Scubapro’s flagship first stage with a second stage engineered to excel in harsh conditions. You get a system that any diver can take on any dive, anywhere in the world, and be assured of rock-solid performance and reliability.

The Scubapro MK25 EVO first stage delivers an ultra-fast breathing response, great sensitivity and extra-high airflow, making it the ultimate do-it-all first stage for all water temperatures.

The Scubapro G260 second stage is the most imitated air balanced second stage of all time. It smoothes out the inhalation effort at varying depths and supply pressures.

The Scubapro R105 Octopus offers dependable breathing performance in a classic downstream design with a dive/pre-dive VIVA switch and reversible hose attachment.

Scubapro G260 MK25 EVO with R105 Octopus includes

• Scubapro MK25 EVO Piston First Stage
• Scubapro G260 Adjustable Second Stage
• Scubapro R105 Octopus
• Scubapro High-Flow Regulator Hose

G260 delivers ultimate breathing sensitivity

Scubapro G260 second stage offers effortless air delivery and outstanding reliability, this is the go-to second stage for cold water or technical diving with a chrome-plated marine-grade brass body.

A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes. A Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water.

Rugged reinforced technopolymer design features Scubapro’s largest second stage casing and diaphragm for the ultimate breathing sensitivity, regardless of position in the water.

High-flow exhaust valve reduces exhalation for better overall breathing comfort.

Scubapro G260 features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer. Metal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.

The ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

• Nitrox compatible up to 40%
• Weight: 9.7oz/275g
• Airflow at 2900psi/200bar: 1800 l/min - 64 SCFM

MK25 EVO is cold water rated

Scubapro MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant air delivery on demand, great sensitivity and extra-high airflow - regardless of the water’s cold.

Air-balanced flow-through piston design provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.

Patented XTIS (Extended Thermal Insulating System) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance.

Anti-freeze protection radically increases breathing reliability when diving in extreme water temperatures.

Scubapro MK25 EVO First Stage Regulator is CE certified according to the latest EN250A European Standards for all diving conditions, including extreme cold water.

Two high-pressure and five high-flow low-pressure ports on a swivel turret maximise hose routing options.

External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

DIN or A-clamp first stage?

Most of our divers prefer DIN fitting on the 1st stage regulator. A DIN regulator has a threaded post which screws into the inside of a DIN tank valve and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank.

YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened.

Both regulators seal to the scuba tank through an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators with their own o-ring.

DIN fittings are commonly accepted as more secure, but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
