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).

The new Apeks RK4 Fins deliver optimum performance and excel for frog-kicking and back-finning underwater, without being too heavy or excessively rigid. 

You'll be conserving energy with these compact, wide-blade technical fins which provide outstanding manoeuvrability in confined spaces and overhead environments, easy finning in open spaces whether during an upstroke or downstroke.

With the RK4 fin, Apeks has Increased the edge of the blade on the side to give you more control underwater, yet kept some flexibility on the fin tip so it doesn't feel too rigid.

The Apeks RK4 Fins have an adjustable fin strap which allows one or both sides to be adjusted back or forward for optimal fit - each side by around 2cm. A nice big durable pull at the back makes it easier to don and doff in a drysuit (although the discerning divers among you worried about entanglement can still cut off the pull-handle while retaining the rubber guard on the spring.

Weight-wise the RK4 fin sits somewhere between the RK3 and RK3 HD. It's neither super heavy nor too rigid, which makes it comfortable for all sorts of divers whether in drysuit or wetsuit - in short, it is a great all-round fin.
