Why Portland?

We’re located on the Isle of Portland (in Dorset) because Portland has been one of the most popular scuba diving locations in the United Kingdom even before we set up operations here back in the year 2000.

On one side, we’re minutes away from the sheltered waters of Portland Marina and Harbour, while on the other, it’s just a brief walk to reach our famous scuba diving destination Chesil Cove and start of the 16-mile-long Chesil Beach.  

Portland’s location makes it ideal for scuba diving, freediving, snorkelling and other surface water sports activities. 

Check out how many wrecks we have around here by clicking on Scimitar Diving's Wreck & Dive Sites chart!

Alongside dive clubs, many instructors and dive schools travel here to train and offer scuba diving certification ranging from open water diver to mixed-gas tech diving or rebreather diving levels.

Whether you’re doing a boat dive from Portland Marina or Castletown or a shore dive at Chesil Cove, Portland is well known for offering many possibilities: Reef diving to wreck diving and night diving, underwater photography or underwater videography. Anything other than cave diving is possible here.

Likely being the best-stocked diving shop in the UK, at Underwater Explorers we offer in-store scuba diving equipment advice and sales, as well as gas fills, to locals and visitors (read About Us).

But... If you’re googling “scuba diving shop near me” like some, look no further, there's DirDirect online.

Here at DirDirect, we list our cutting-edge equipment for worldwide delivery and we’ve got you covered whatever your level of diving: We’re your local dive store wherever you are in the world.

All that with over 20 years of experience especially in technical diving, from training to equipment, advice and sales.

If you dive deep, dive cold, or often find yourself on silty bottoms, the Scubapro MK19 EVO G260 Regulator is for you. While you don’t need to dive in less-than-pristine waters to appreciate this system, it’s a great choice for cold water or harsh conditions, which is why tech divers and cave explorers just love this reg.

The compact MK19 EVO first stage is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets.

The G260 second stage is the most imitated air-balanced second stage of all time. It 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.

Put these together, and you’ve got a winner, Scubapro MK19 EVO G260 Regulator.

Scubapro MK19 EVO G260 Regulator includes

    • Scubapro MK19 EVO First Stage
    • Scubapro G260 Adjustable Second Stage
    • Scubapro High-flow Regulator Hose

        G260 offer 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.

        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.

        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 Second Stage 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
        • Maximum low pressure: 203psi/14bar

        Scubapro MK19 EVO features

        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.
