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 Hollis Katana 2 Single Sidemount System sets a new standard in sidemount diving. Designed in collaboration with Edd Sorenson from Cave Adventurers, Hollis developed a unique new "Quick Fit System”, which allows users to easily tailor the one-size-fits-all harness to their specific size or adjustment preference in a matter of minutes.

Katana 2 breaks away from traditional designs and offers more customisation and versatility. Hollis added more lift, weight capacity, single and dual bladder options and the best quality materials for which Hollis has always been known.

“QFS” Quick Fit System offers fine-tuning of the torso height between small and large divers for a true one size fits all.

Lift capacity is 40lbs with innovative wing design to keep diver profile low and without the “turtle shell effect”, which causes drag.

Standard weight capacity 20lbs, to offset added buoyancy in cold water with drysuits and thick undergarments.

Hollis Katana 2 is also the first sidemount harness in the world to be designed with closed circuit sidemount capability, with integrated mounts for the popular KISS Sidewinder.

Hollis Katana 2 is also available as a Katana 2 Dual Sidemount System for wetsuit diving.

Hollis Katana 2 Single Sidemount System features

  • “H” or “Y” style harness configuration
  • Easy-to-reach attachment points for accessories on the side of the wing
  • Innovative top dump allows venting of gas with outbreaking trim or reaching behind the wing like in other designs
  • Integrated sidemount CCR mount
  • Single bladder ideal for recreational sidemount with two cylinders or in a Drysuit for redundancy
  • 20lb weight capacity
  • QFS one-size-fits-all design
  • 40lb lift capacity
  • 2-year standard warranty
