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.

With smart AI technology, the Shearwater Swift Transmitter creates a highly reliable connection, listens for other transmitters, and only communicates when the channel is clear by avoiding collision with other signals. Now, divers can use multiple transmitters near each other without worrying about potential interference.

This advanced technology is leveraged by Shearwater's new firmware, which includes support for up to 4 transmitters on compatible Shearwater models. This firmware also includes exciting new features like advanced screen customisation and AI Sidemount mode.

The no-tools design makes it easy to remove and replace the Shearwater Swift Transmitter from the 1st stage (gone is the need to find a particular size tool to tighten or loosen the transmitter, making it perfect for travel!)

A double O-ring seal protects a user-replaceable 3v CR2 lithium battery, offering up to 300 hours. The LED status indicator lets the diver know things are functioning as they should at a glance during setup.

Constructed from high-quality oxygen-compatible components, at only 135g and 76mm x 34mm, the Swift is compact, rugged and rated 200m depth and 300bar gas pressure.

Compatible with all existing air-integrated Shearwater dive computers and many other computers already on the market.
