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.

Ammonite LED ONE Mini backup light is a miniature, durable and reliable version of the all-around Ammonite LED ONE Backup Torch.

Ammonite LED ONE Mini  offers power of simplicity

As leading technical diving agencies advocate storing 2 backups alongside a reliable primary light, Ammonite Systems released the LED ONE Mini.

The idea behind this torch concept was to enhance your diving safety and offer the duplicity of compact backup lights.

The LED ONE Mini was created to guarantee a failsafe backup against any primary light failure situation.

the Ammonite LED ONE Mini backup light offers a simple construction, impressive performance, a new ergonomic military-style grip and a long burn time.

Made out of rugged materials with a great design, this powerful yet compact backup torch boasts an impressive 400 lumens output and 5 hours of burn time powered by two CR123A batteries (not included).

Confidence in excellent performance and reliability

LED ONE Mini’s reliability stems from its simple but robust construction, materials, build quality, and minimal reliance on electronics.

The LED ONE Mini 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 6mm tempered and scratch-resistant glass.

The LED ONE Mini 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 when switching on and off underwater.

High light intensity, long operation time

The LED ONE Mini Backup Light utilises a directly powered 5W LED chip with an outstanding lifetime, lasting more than 100,000 hours of constant burning.

Two CR123A or equivalent rechargeable batteries can be used as the power supply source. Batteries are not included.

Ergonomics of Ammonite LED ONE Mini Backup Light

This incredibly rugged and waterproof backup light is extremely easy to use. The user switches it on and off with just a simple quarter-turn of the head.

LED ONE Mini easily fits in a jacket pocket (max. length: 126mm, max. width: 42 mm) and can be conveniently attached to the diving harness.

The exterior is now shaped for a firm and easier grip, additionally, it’s much simpler to stow the light with a bungee loop when diving.
