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.

Features of Scubapro S600

Scubapro S600 Second Stage is a compact, high-performance, air-balanced second stage with multiple diver adjustment possibilities. It adapts to all diving conditions and the diver's taste.

The air-balanced valve technology of Scubapro S600 Second Stage features a balancing chamber in the second stage mechanism, slightly offsetting the force of the downstream air entering from the first stage. This reduces spring tension and decreases the inhalation resistance to the lowest possible level. The result is super smooth breathing in all conditions.

Precision moulded carbon fiber and technopolymer housing: low friction, lightweight, corrosion and cold water resistant for long life and sturdiness.

User controls of the S600 include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.

The ultra-comfortable orthodontic Scubapro mouthpiece of the S600 is easy to grip yet doesn't inhibit airflow.

  • Nitrox ready for up to 40%
  • Weight: 193g
  • Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM
  • Maximum low pressure: 203psi/14bar

MK25 EVO first stage features

Scubapro MK25 EVO First Stage Regulator 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 First Stage Regulator 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.

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.
