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 OMS SmartStream Quick Adjust Assembly allows a continuous loop, one-piece harness to be used as an adjustable one which will fit most harnesses and work with any 2-inch wide webbing.

This quick-adjust system was developed to alleviate adjustment challenges that may arise while donning a heavy rig. B

y pulling the waist straps forward, the shoulder straps secure to the diver’s shoulders and back - allowing proper adjustments to be instantly achieved.

This assembly is available with stainless steel or aluminium hardware.

How OMS SmartStream Quick Adjust Assembly works

  • Each webbing strap is threaded through either side of the backplate at the waist point and held in place with tri glides.
  • The metal loops face inwards towards the diver and are held fixed by the straps.
  • The waist strap of the harness is then threaded through the loops and then the sockets of the OMS straps. It will slide through that way.
  • Buckles and D-rings then lock it into a maximum adjustment position so it cannot fully slip out.

We also have the Smartstream harness kit that comes with the quick adjust assembly if you are starting from scratch to add a harness system to your backplate.
