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.

An octopus should breathe easy and not add panic to a panic situation. It should travel light and be ready to perform even though rarely used. It should not be an afterthought. The Atomic B2 Octopus is all that and more—a clone of the Atomic popular B2 primary Second Stage.

Titanium B2 Octopus

A Safe Second may not be your first choice for air supply. But the B2 Octopus could be. Since a conventional Octopus is not used as often as a primary, corrosion could set in and degrade performance.

The all-Titanium design and components of the Atomic B2 Octo make it more reliable and ready when you need it. The B2 Octo breathes just like a primary, making it the first safe second choice for almost any dive situation.

The Best Features of the Atomic Family

The B2 Octopus is not a brother or a cousin of the B2 primary second stage. It’s a clone. The same Atomic Regulator family design, engineering, precision manufacturing and features are all there.

The patented Atomic AFC Automatic Flow Control and Titanium Seat Saving Dynamic Orifice ensure crisp, natural breathing performance. The patented PVD-coated Brass Comfort Swivel ensures easy movement. The Neon Yellow cover and extra-long 36” hose are the only differences.

Comfort Swivel

Divers also shouldn’t have to worry about turning, twisting or looking over your shoulder. The popular Atomic Comfort Swivel removes that concern by allowing 30° range of motion without hose binding, pulling or kinking. The B2 Comfort Swivel is polished Stainless Steel with black PVD coating.

Atomic B2 Octopus features

The B2 OCTO is the most comfortable and easy-to-use Safe Second ever designed with all-Titanium construction for corrosion protection and lightweight.

All Atomic Aquatics Safe Seconds feature our exclusive 2-Year / 300 Dive Service Interval and Limited Lifetime Warranty that is not contingent on proof of service.
