Scubapro S620Ti Second Stage Regulator is reliable and easy to breathe

The Scubapro S620Ti Second Stage Regulator embraces the best features of Scubapro's renowned S600 in an upgraded, state-of-the-art design.

Delivering excellent performance, the S620Ti's work of breathing has been reduced by 37% over the Scubapro S600 second stage, providing effortless airflow under all dive conditions.

The large purge button improves water circulation, and the new exhaust tee directs bubbles out of the field of view. It's a stellar combination that can be relied upon to deliver top-line performance in all dive conditions.

The full titanium inlet tube is ultralight, the large purge button improves water circulation, and the re-engineered exhaust tee increases performance while directing bubbles out of the field of view.

Air-balanced valve smoothes the inhalation effort at varying depths and supply pressures.
Rugged reinforced technopolymer case and the front cover can withstand years of aggressive diving.
Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
Uses the S600's large diaphragm inside a compact casing for maximum breathing sensitivity.
User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
Super-flow hose features an oversized bore allowing more air flow on each inhalation.
Ultra-comfortable compact orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
Airflow at 2900psi/200bar: 1850 l/min.
Nitrox Compatible up to 40%

MK17 EVO 2 First Stage features

The Scubapro MK17 EVO 2 First Stage elevates performance and reliability. It also improves compactness and freezing resistance. Consequently, it stands as a top-tier sealed diaphragm first stage from Scubapro. For many years, the MK17 line has been Scubapro’s leading sealed diaphragm first stage.

Moreover, the MK17 EVO 2 is more compact and lightweight. It exceeds both its MK17 EVO predecessor and the MK19 EVO. Furthermore, a NEW forged body and dry chamber enhance it. A twin spring layout increases reliability and compactness.

Additionally, two newly designed HP ports sit at a 15-degree angle. This design simplifies HP hose routing. Therefore, it eliminates the need for a transmitter adapter. A Scubapro transmitter now attaches directly to the first stage.

Sealed balanced diaphragm design creates a compact first stage. This suits cold water or contaminated diving conditions. Besides, an air-balanced diaphragm delivers consistent airflow. It does this regardless of depth, tank pressure, or breathing rate.

Furthermore, a dry chamber is completely environmentally sealed. A dual diaphragm system keeps out contaminated water. The rib design enhances heat exchange. This makes the first stage cold waterproof.

Nitrox compatible up to 40%.
Diaphragm 1st stage.
DIN fitting.
Chrome-Plated Brass construction.
Suitable for warm, cold, and temperate waters.
Two HP Ports.
Four LP Ports.

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.
