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 Santi BZ420X Heated Undersuit is an advanced version of Santi’s flagship model, designed for even greater warmth and comfort while diving in a drysuit. 

It offers unparalleled thermal comfort even in extreme conditions thanks to construction improvements and new materials.

The heated BZ420X undersuit is designed to comprehensively protect the whole body of a diver from the cold. The heated undersuit heats the trunk, thighs and arms evenly.

It is designed to be worn on top of a thin base layer allowing most of the generated heat to be passed directly to the diver’s body.

The heated Santi undersuit gives you the best thermal protection underwater. It keeps you warm and comfortable while heating, even when the batteries are low or completely drained.

What’s new in the BZ420X Heated Undersuit?

A high-quality and thicker inner layer provides superior thermal insulation, making it warmer than BZ400 Extreme.

The new cable layout ensures more even heat distribution and more efficient heating.

A new, smooth inner material makes donning and doffing easier. The “brick” pattern of the improved quilting enhances flexibility and body fit.
