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 Ammonite LED ONE Backup Light is universal and reliable dive light. Ammonite created LED ONE as a fail-safe backup against any primary light failure situation.

It offers a simple, robust construction, impressive performance, a new ergonomic military-style grip and long burn times.

The LED ONE Backup Light with rugged materials, and design is a powerful yet compact backup torch with an impressive 400 lumens and 6-hour burn time, all powered by three AA batteries.

Confidence in excellent performance and reliability

Ammonite LED ONE Backup Light’s reliability is its key feature, which stems from its simple but robust construction, the materials used, as well as build quality and minimal reliance on electronics.

The LED ONE body is machined from a solid piece of Delrin®, an exceptionally rigid and durable construction thermoplastic. The head is made from hard anodised aluminium, which makes it resistant to abrasion and weather factors.

The LED is protected by a 6mm tempered and scratch-resistant glass, while the LED ONE head is machined with a long thread and is protected with three beefy o-rings.

It guarantees leak tightness for immersion to depths of 200 metres and protects the device from accidental water ingress.

High light intensity, very long operation time

The Ammonite LED ONE Backup Light delivers a tightly focused light beam of highly visible cold white light.

This backup torch utilises a directly powered 5W LED chip with an outstanding lifetime, lasting more than 100,000 hours of constant burning.

Three easily accessible AA or equivalent rechargeable batteries can be used as the power supply source. Batteries not included.
