As it's an active store visited by divers from around the country and world regularly, if we can't make it to the phone for any reason please leave a message and we'll get back to you asap.

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.

  • Corrugated hose top centre
  • Inflator hose included
  • Interior zipper backing
  • Dump valve lower left

  • Inner bladder polyurethane material, ultrasonically welded fittings and seams

Backplate with OMS SmartStream Harness

The OMS Backplate with SmartStream Harness was developed to alleviate adjustment challenges while donning a heavy rig with webbing without compromising from the continuous loop.

Whether donning the wing/harness or underwater, divers can make necessary adjustments by pulling the waist straps forward through specially designed loops, tightening the shoulder straps and securing the wing/tanks to the diver’s shoulders and back.

Proper adjustments can be instantly achieved by using OMS SmartStream Harness, while it is also possible to thread the webbing in the classic DIR way with pre-adjustments.

The uniquely adjustable OMS SmartStream system allows the use of OMS weight pockets or, if the pockets are not required, a loop to hold a canister light.

The aluminium backplate comes with lightweight aluminium hardware, buckles, tri glides and D-rings, whereas the stainless backplate will come with steel hardware.

  • On-the-fly adjustable easy on-and-off with OMS vertical weight pockets (not included)
  • On-the-fly adjustable easy on-and-off without weight pockets / with canister holder loop & extra buckle
  • Standard "DIR" configuration with pre-adjusted harness settings
  • One size fits all
  • Comes fully assembled with aluminium or steel backplate
