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.

All that with over 20 years of experience especially in technical diving, from training to equipment, advice and sales.

The APEKS DST First Stage: High-Performance & Versatile

The APEKS DST first stage regulator is a versatile, high-performance option for divers of all levels and is popular among technical and sidemount divers.

It’s based on the renowned DS4 first stage, including all its outstanding features, but adds a number of features from a swivel turret for improved hose routing, a second HP port on the opposite side of the body, and even the option to add a 5th medium pressure port.

The standard medium-pressure ports are all mounted on a rotating turret, allowing optimal hose routing for all configurations, whether diving a single tank, twinset, or using stage bottles. The 5th MP option makes it ideal for sidemount diving.

The swivel turret, 2 HP ports, and up to 5 MP ports make the Apeks DST a very versatile regulator that can be used for various diving applications.

The Apeks DST first stage, like the Apeks DS4, features an over-balanced design, which means that the intermediate pressure increases more than the ambient pressure as a diver descends, which results in a smoother breathing experience at depth.

As a regulator that uses a diaphragm to control the gas flow instead of a piston, it is considered more durable and more reliable in cold water.

The DST 1st stage also has an environmentally sealed dry chamber preventing water from coming into contact with the first stage spring to prevent freezing.

In summary, similar to its sibling, the Apeks DS4, the DST is a reliable workhorse with many additional features at a great price point.

Being a well-respected regulator in the technical and sidemount diving world and often a first-choice regulator for stage bottles and sidemount, the DST is ideal for twinsets and single tank configurations.

APEKS DST first stage features:

  • Swivel turret for improved hose routing
  • Four medium-pressure ports (with the option of a fifth port) on the turret
  • Two high-pressure ports on opposite sides of the body
  • Diaphragm-type design for durability and cold-water performance
  • Over-balanced design for smooth breathing at depth
  • Environmental dry chamber to prevent freezing
