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

Scubapro S270 Octopus

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.
