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.

Apeks has developed unique first stages for use on a twinset, Apeks TEK3 Twinset Regulator Set. This system’s benefits are a minimised risk of accidental snagging, no hose kinking and easier access to the manifold valves. TEK3 looks great too!

TEK 3 Twinset Regulator Set includes

  • Left Hand Apeks TEK3 first stage
  • Right Hand Apeks TEK3 first stage
  • 2 x Apeks XTX50 second stages
  • 210cm rubber main regulator hose
  • 61cm rubber backup regulator hose
  • Apeks Bungee Connector Kit for backup regulator

Apeks TEK3 First Stages

Each first stage has three medium-pressure ports and one high-pressure port. They are over-balanced, cold water compatible and extremely robust. The ports on the TEK3 first stages are oriented so that all hoses will route downward to provide the streamlined configuration required by technical divers.

Not only is the TEK3 suitable for twinset use but it is equally suitable for single-cylinder or stage-cylinder configurations - offering perfect, snag-free hose positioning.

Apeks TEK3 Twinset Regulator Set also comes with two diver adjustable Apeks XTX50 second stages.

Apeks XTX50 Second Stages

XTX50’s second stage can be converted from a right-handed hose configuration, as supplied, to a left-handed one. This feature is known as the Reversible Venturi System. Changing the regulator to a left-handed configuration is quick and simple and can be performed by any Apeks Authorised Service Technician.

The XTX50 Second Stage incorporates the feature of Diver Changeable Exhausts system. This system allows the diver to change from a small exhaust tee to a large one. This gives the user a choice of the wider exhaust tee for minimal bubble interference, essential for underwater photography, or the narrow exhaust tee for a smaller compact and comfortable set-up.

The Apeks XTX50 second stage incorporates a two-shot high-strength composite front cover, improving the durability of the most vulnerable part of the demand valve.

The ergonomic Venturi lever of the Apeks XTX50 Second Stage has been designed to reduce the amount of grit ingress. A silicone exhaust valve has been used on the Apeks XTX50 Second Stage, improving breathing performance.
