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.

Recommended practice for suit inflation cylinder

  • Never allow the suit inflation cylinder to fully empty underwater
  • Storing cylinders with at least 2 bar of pressure in them
  • Keeping/transporting any empty cylinder with the valve closed
  • Drying and capping valves when the regulator is not attached
  • Periodic check against moisture/water buildup in the cylinder

Do suit inflation cylinders need testing?

Cylinders that may, during normal use, lose all gas pressure above ambient when underwater, such as side-mount, bail-out, marker buoy, buoyancy compensator, and suit inflation cylinders are at a greater risk of water ingress and internal corrosion when empty.

If freshwater is present in a cylinder, this can mean the loss of more than 2mm of the thickness of the cylinder wall within 6 months. This is increased to more than 5mm in salt water. (Diving cylinder walls are generally between 2 and 5mm thick).

While testing of the diving cylinder remains at 2.5 years for an internal visual and 5 years for a full hydrostatic test in the UK, a more frequent visual inspection by a certified test centre for suit inflation cylinders is recommended.

Deliveries outside the UK

Due to aviation regulations, the cylinder and valve will be shipped disassembled. It will be the customer’s responsibility to have the cylinder and valve re-assembled.
