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 XDeep SMB 130cm Open is simply a long tube open at one end to inflate it using a regulator, exhaled bubbles or other means.

No dump valve is required as the air can expand out of the end of the tube; care must be taken to keep tension on the bouy to keep it upright and avoid air spilling out.

The reflective strip uses 3M Scotchlite reflective tape, which carries a Solas maritime visibility certificate.

A clear plastic tube is fitted to the side of the XDeep SMB to provide a place for small notes or a glow stick.

A big sling underneath makes attaching a spool or reel easy and filling the bag a breeze. A small loop of bungee keeps the SMB neat and tidy in storage.

The XDeep SMB 130cm Open is available in orange and yellow.
