S620Ti is reliable and easy to breathe

The Scubapro S620Ti Second Stage 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%

Scubapro MK19 EVO First Stage

The compact, lightweight Scubapro MK19 EVO First Stage, with its environmentally sealed system, dry ambient pressure chamber, plus user-friendly LP port swivel turret, this regulator system is uniquely well-suited to handling cold water and the harsh diving conditions often encountered by technical divers.

The Scubapro MK19 EVO adopts a new dry ambient pressure chamber that enhances freezing resistance while ensuring consistent airflow and maximum durability in the coldest conditions.

With a swivel turret and five LP ports which maximise hose routing options, this first stage is built not only for professional, military and technical divers but also for recreational divers who need superb cold water performance in a lightweight, small, compact size.

The MK19 EVO is designed to be the ultimate first stage for cold water or contaminated diving conditions. Its design makes it substantially smaller and lighter than the original MK19. 


Air-balanced flow-through piston in a chrome-plated marine-grade brass body provides constant and effortless airflow unaffected by depth, tank pressure, or 
breathing rate 


An environmentally sealed system prevents water and pollutants from fouling the inner mechanism. Its dry chamber has a double spring, making it more compact and reliable. 


Two opposing high-pressure ports allow the first stage to be positioned either up 
or down and provide an optimum hose/transmitter layout. The swivel turret has four High-Flow LP ports plus one axial Super High-Flow LP port to maximise hose routing options. 


• Nitrox compatible up to 40%
• Weight: INT 232, 885g; DIN 300, 665g 

• Airflow at 2900psi/200bar: (l/min/SCFM): >6,900/244 

• Intermediate pressure (psi/bar): 133-142/9.2-9.8 


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.
