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.

OMS Smartstream Signature Wing System

The OMS SmartStream Signature System features a quick-adjust harness developed to alleviate adjustment challenges which may arise while donning a heavy rig. By pulling the waist straps forward, the shoulder straps secure to the diver’s shoulders and back - allowing proper adjustments to be instantly achieved.

This uniquely adjustable OMS system allows the use of OMS weight pockets or a place to hold a canister light. The system is delivered fully assembled with Performace Mono 32lbs Wing in different colours, backplate, harness, storage pac, weight pockets and required hardware.

This modular system gives you the choice to use the harness in its adjustable configuration with or without weight pockets (pull the waist straps forward to don and push them off to doff) or simply as a standard DIR fixed harness.

Ali backplate will have light weight aluminium hardware, buckles, triglides and D-rings whereas stainless backplate will come with SS hardware. With this innovative design from Ocean Management Systems all you need is a cylinder and your regulators.

The system ships fully assembled on a single tank wing with the OMS Weight Pockets already installed. The Performance Mono Wing also has stabilizing bars built into the wing to reduce tank shifting during a dive.

One size fits all

The OMS SmartStream was developed to alleviate adjustment challenges which may arise while donning a heavy rig with webbing without compromising from the continuous loop. Whether when donning the wing/harness or underwater, divers can make necessary adjustments by pulling the waist straps forward, through specially designed loops, tightening the shoulder straps and securing the wing/tanks to the diver’s shoulders and back.

Proper adjustments can be instantly achieved by using this system while it is also possible to thread the webbing in the classic DIR way with pre-adjustments.

The uniquely adjustable OMS SmartStream system allows the use of OMS weight pockets or, if the pockets are not required, a loop to hold a canister light.

This modular system gives you the choice to use the harness in three configurations.

  • On the fly adjustable easy on-and-off with OMS vertical weight pockets
  • On the fly adjustable easy on-and-off without weight pockets / with canister holder loop & extra buckle
  • Standard "DIR" configuration with pre-adjusted harness settings

Apeks MTX-RC Long Hose Regulator Set

The Apeks MTX-RC Single Cylinder Long Hose Regulator Set is designed for the diver that prefers a long hose configuration on a single cylinder. It is also the perfect set-up for the recreational diver looking to transition into twinset diving in the future, as the addition of another first stage creates a twinset regulator configuration.

Combining rugged, military grade engineering with the super-smooth breathing experience that Apeks regulators are renowned for, the MTX-RC single cylinder set dives your way.

Featuring the same freeze-resistant technology enjoyed by the whole MTX-R range, the MTX-RC resists freeflows in even the coldest temperatures, while offering the user the additional flexibility to dial it out for a comfortable breathe in less extreme environments.

All this is achieved using an innovative first stage design that protects the regulator from freezing and a full set of user controls on the second stage to adjust the breathing performance based on the diver’s individual needs.

Apeks MTX-RC Long Hose Regulator Set includes a tactical style messenger bag to keep your regulators safe on your travels. Perfectly sized for a laptop, it’s also your new work bag!

MTX-RC First Stage is cold water rated

The Apeks MTX-RC first stage has a unique over-balanced diaphragm design. As the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase faster rate than ambient. This results in superior performance at depth.

  • Satin plated brass body with heat exchanging ribs for maximum thermal performance.
  • Break through, innovative over-moulded first-stage endcap and environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage.
  • Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
  • 5 x medium pressure ports, 4 mounted on a rotating turret for improved hose orientation
  • 2 x angled high pressure ports for optimal hose routing and fitting of transmitters.
  • Double swivel hose for greater freedom of movement and comfort.
  • Easy to grip DIN hand-wheel or over-moulded yoke hand-wheel, only requires one hand to release.
  • Tested for Octopus use - EN250A to 60 metres cold water.
  • Nitrox/Oxygen compatible – Up to 40% O2 outside the EU (European Union).

Second stage with Breathing effort adjuster

The oversize breathing effort adjuster of MTX-RC second stage makes adjustment easy in cold water whilst wearing gloves. Protective bumpers protect the second stage from impacts and scratches in the most vulnerable places.

  • Ergonomic and simple to use venturi lever.
  • Large purge button.
  • Reversible second stage for either a left or right hand gas supply configuration.
  • A heat exchanger (patented) dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water for a more comfortable breathe.
  • Features an innovative Diver Changeable Exhaust system (DCE). The system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. The regulator is supplied with both sets of exhaust tees.
  • Comfo-bite mouthpiece
  • Flexible nylon braided hose, which has better cold water performance than traditional rubber hose.
