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 self-sealing AP Diving SMB is inflated by simply purging a second stage in the open end when underwater. The really clever bit is in the mouth where the unique self-sealing baffle - or duckbill valve - is forced shut, forming an airtight seal, on inflation.

This self-sealing SMB also features a stream-lining flap which folds back over the mouth and prevents any sea-anchor drag effect when used in a current.

The AP Diving SMB can be used as a delayed SMB or inflated at the start of the dive and towed as a standard surface marker.

The SMB rolls up neatly and can be stowed in a pocket, attached to an external d-ring or wrapped in the dedicated SMB velcro pouch.

At the surface, the SMB is pulled upright by tension on the line and clearly marks the diver's position. The baffle prevents air spillage, and the buoy remains inflated making it easy for the surface crew to track the diver or for the diver to hold aloft and wave if separated from the boat.

A message slate, ID marker or reflector can be tied to the top eyelet.
