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.

Fourth Element J2 Baselayer Complete - Men's set includes J2 Baselayer Top, Leggings and Fourth Element 5L Drysack.

The Fourth Element J2 Baselayer was designed to wick perspiration away from the skin and maintain a dry zone next to the skin. Air is a better insulator than water; consequently, the baselayer ensures better thermal protection.

Keeping the skin dry can be critical to success, whether staying warm or preventing infections. The Fourth Element J2 Baselayer system furthers this performance with tried and tested anti-microbial silver ions embedded within the fabric’s fibres. This enables long, repetitive wear without the risk of developing skin infections– which was critical on the J2 expedition.

The Fourth Element J2 Baselayer was developed for the US Deep Caving Team’s 2013 expedition to explore Cheve Cave System in Mexico. With excellent anti-microbial performance thanks to silver ion technology, and outstanding wicking from a unique fabric, it is designed for extended use under a drysuit.


Silver ions are incorporated into the fibres when manufactured, ensuring that the bacteriostatic and ant-fungal properties of the fabric last. This cannot be washed off. The silver ions prevent the formation of bacterial cell membranes, preventing most bacteria from growing in the garment’s fibres. However, this will not adversely affect the naturally occurring bacteria on the skin.

Fourth Element J2 Baselayer performs when wet

The J2 wicking performance also comes into its own when the fabric gets wet. Water is wicked away from the skin, and with the right combination of drysuit underwear, further away through the fibres of the undersuit. Even in the event of a suit flood, the Fourth Element J2 will retain some of its performance.
