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.

The Atomic T3 Regulator is the Atomic Aquatics signature regulator. Atomic forged a new Titanium standard for the T3, making it the absolute finest regulator you can own, regardless of price.

The T3 Regulator delivers unprecedented reliability and performance. Incredibly lightweight and corrosion-resistant materials make the T3 a perfect choice for travel in exotic locations where finding service is a remote concept.

Pair it with Atomic Ti2 Octopus.

Atomic T3 Titanium Regulator

T3 Titanium Regulator

Developing the lightest regulator in the world requires heavy reliance on precision engineering and machining. First and second-stage components are precision-machined from solid Titanium billet.

The T3 first stage is designed using minimal material and machined from a solid piece of Titanium, requiring 23 individual operations.

All machining operations are performed in a single continuous milling session at Atomics’ Atomica manufacturing facility. That means each component is carefully and expertly crafted under our watchful eyes to conform to only the most exacting standards.

Comfort Swivel

Divers deeply admire many exclusive features of Atomic second stages that make diving easier. One of the most acclaimed is the Atomic Comfort Swivel which allows 30° rotational movement without hose binding or kinking.

The T3 Comfort Swivel is all-Titanium with black PVD coating for the highest level of corrosion resistance you can take in the ocean. Once you dive more comfortably with it, you’ll wonder why no one else ever thought of it.

Automatic Flow Control

The Atomic AFC is so advanced they were granted a US patent for its design. The venturi effect inside a second stage makes it breathe easy, and the Atomic AFC eliminates the manual adjustment normally needed to regulate venturi effect as you dive deeper.

No dials to turn or buttons to push, but they include a rapid adjustment knob for rare special situations. A computer-designed airfoil inside the mouthpiece is connected to a pressure-sensing diaphragm, allowing the airfoil to change position in response to depth.

The AFC is the reason Atomic regulators breathe with a comfortable natural feeling at any depth.
