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.

Innovations in design mean that the Apeks MTX-R Regulator Set perform in almost freezing water at a depth of over 60 metres, something that very few other regulators on the consumer market can boast. The MTX-R is not just an extremely reliable regulator but also very easy to service “ in the field”.

The military has been using Apeks regulators for over 20 years and now Apeks have put that military expertise into a brand new military specification regulator, exclusively for the consumer market.

The “M” in MTX stands for Military and the “R” for recreational version and the new MTX-R is based on the MTX, a regulator that was developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test.

Apeks MTX-R Regulator Set includes

  • Apeks MTX-R First Stage
  • Apeks MTX-R Second Stage
  • Apeks Flexi Regulator Hose
  • MTX-R Messanger Bag

Over-balanced First Stage

The cold water rated Apeks MTX-RC first stage features a unique over-balanced diaphragm design – as the diver descends, the overbalancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.

Over-moulded innovative endcap and environmental diaphragm, a forged 1st stage body offers maximum thermal performance.

The Apeks MTX-RC has forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation. Angled HP ports for optimal hose routing and fitting of transmitters.

  • Suitable for cold water use (below 10°C / 50°F)
  • The 5th 3/8” UNF medium pressure port includes a protective bumper when not in use.
  • Forged first stage body with heat exchanging ribs for maximum thermal performance.
  • Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
  • Nitrox/Oxygen compatible – Up to 40% O2 outside the EU (European Union)

MTX-R Second Stage

The Apeks MTX-R Second Stage Regulator performs in almost freezing water, something that few other consumer market regulators can boast.

The reversible (right and left hand) Apeks MTX-R Second Stage has a redesigned and enlarged, patented, heat exchanger which surrounds the valve mechanism, dissipating the cold caused by gas expansion.

Metal has also been incorporated into the front cover. Large protective elastometer bumpers on the sides and top protect the 2nd stage, which comes with a comfobite mouthpiece.


In addition to its extreme cold water ability, the Apeks MTX-R Second Stage Regulator is rugged, strong and designed to withstand the knocks and bumps that come with life on an expedition.


  • Simple to use second stage with no dive adjustment controls and a reduced chance of free flow.
  • Reversible (left or right hand)
  • Patented heat exchanger surrounds the valve mechanism, dissipating the cold caused by gas expansion while drawing in the warmth of the ambient water.
  • Comes with comfort-bite mouthpiece

Tested for octopus use to 60m in cold water, this regulator set from Apeks is truly unique. The MTX-R is not just an extremely reliable regulator but also very easy to service “ in the field”.
