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 Fourth Element Thermocline Shorts - Men's are equivalent to 2mm neoprene. They are designed to be worn in warmer waters or under a wetsuit to increase thermal protection. The shorts can also be worn with the Thermocline Vest for a lightweight shortie wetsuit.

The Fourth Element Thermocline Shorts - Men's are a smart alternative to board/swim shorts as the close-fitting material won’t ride up under a wetsuit. Worn under board shorts, the Thermocline Shorts can provide that extra thermal protection allowing you to extend your season in the water with the freedom and comfort of shorts before moving to a full neoprene wetsuits. A high back means it won’t ride down when paddling or swimming.

Equivalent to 2mm neoprene

The original neutrally buoyant wetsuit system, Fourth Element Thermocline, is lightweight, machine washable and equivalent to a 2mm neoprene wetsuit without the wetsuit, making it perfect for those allergic to neoprene. Now made using recycled ‘Ghost’ fishing nets, Thermocline is part of Fourth Element's OceanPositive collection.
