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 DUI FLX Extreme Maximum Mobility Drysuit is perfect for advanced technical divers and the most popular option for exploration divers.

DUI set out to develop the most comfortable and flexible drysuit to provide maximum protection for technically demanding conditions. In that mission, they discovered the perfect combination of materials and craftsmanship.

Using trilaminate fabric made of a Polyester inner and outer layer with the butyl-rubber interior slightly thicker than the TLS350 - adding additional puncture resistance. They then added Cordura overlays on the legs for increased durability though soft to the touch, just like your favourite pair of jeans.

DUI suits are famous for their exceptional fit allowing for a maximum range of movements while wearing the suit underwater.

All DUI drysuits have a 7-year warranty against defects in materials and workmanship with a 40-year history of standing behind this warranty.

Every drysuit is inspected multiple times throughout manufacturing and receives a final water test before leaving the factory.
