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 NEW Fourth Element Arctic Top with a zip and pockets is designed with a long body portion to ensure adequate overlap between the top and trousers.

Now with a a low, full front zip for easy donning and to improve overall fit. Thumb loops prevent the sleeves from riding up during donning.

Redesigned Fourth Element Arctic

The 2024 redesign is more than just producing a more OceanPositive product. It builds on Fourth Element’s more than 20 years of experience developing thermal garments and the feedback from some of the many thousands of users of the original Arctic in the field.

The Arctic top now features a full-length zip, allowing easier donning and greater adjustability during the surface interval. The dropped height of the neckline ensures that there is not too much bulk around the neck.

The addition of pockets complements the modifications to the pattern to improve fit and, therefore, the overall thermal performance.

Now, with 80% recycled polyester in the outer and 100% recycled polyester in the internal layer, the Arctic undersuit system has also become part of Fourth Element’s mission to become OceanPositive.

The Arctic creates a micro-climate around the diver

Constructed with comfort and utility in mind, the minimalist design provides outstanding performance under drysuits. In a layering system, the Arctic is suited for use underneath neoprene, membrane and trilaminate suits.

Arctic’s two layers of high insulation and low bulk fabric ensure exceptional levels of thermal protection. Using a unique combination of fast wicking and high insulation fabrics, the Arctic creates a micro-climate around the diver, keeping the body dry and warm.

A high-density inner fleece provides superior insulation, with maximum comfort and wicking, whilst the outer layer, which has a water-repellent finish, ensures a snug fit.

Reduced rate of cooling

The Arctic requires less loft to perform due to more effective management of air held in the suit’s fibres. Instead of maximising the thickness of the layer of air near the skin, the Arctic minimises the movement of air within, reducing the cooling rate without any risk of trapping the air and preventing its release from the dump valve.

Field testing

Backed by years of field testing by the Norwegian Navy, the British Antarctic Survey Dive Team, the French Marines and the Danish Navy, the Arctic was designed using high-technology fabrics and has been tested in real diving conditions from the Arctic to the Antarctic.
