Scubapro A700
The Scubapro A700 second stage, with its metal casing, screw-down casing cover, metal valve housing and over-molded accents, exhibits a real muscularity in design. It can withstand years of aggressive diving.
The A700 is an air-balanced second stage that reduces inhalation effort when diving at varying depths and supply pressures. It is a rugged, reliable breather with effortless inhalation and unmatched ease of exhalation.
The controls’ user controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
High-flow exhaust valve allows air to exit more freely and lowers the exhalation effort while directing bubbles away from your mask.
The A700 comes with an ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

Scubapro MK25 EVO
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.
MK25 EVO is cold water rated
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 is CE certified according to the latest EN250A European Standards for all diving conditions, including extreme cold water.
Excellent hose routing
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.
- Nitrox compatible to 40%
- 300bar DIN connection
- Weight: 572g
- Airflow at 2900psi (l/min/SCFM): >8500/301
- Intermediate pressure 9-9.8bar
- 2 High Pressure Ports
- 5 Low Pressure Ports
- Chrome-plated brass
Scubapro S270 Octopus
The ideal backup breather for your dive system, the Scubapro S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be counted on to deliver top-notch breathing performance when needed.
Air-balanced Scubapro S270 Octopus smoothes out the inhalation effort when diving at varying depths and supply pressures.
Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort.
Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can't grab onto when diving in extreme cold water.
The compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximize airflow.
High-viz yellow super-flow hose is 1m long with an oversized bore allowing more air flow on each inhalation.
- Dive/predive switch prevents freeflows when not being used
- Compact and efficient exhaust tee minimizes exhalation effort
- High-viz yellow front cover stands out, making it easy to spot when needed
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.
