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.

FinnSub Finn Light 2500 XLong Torch with 2500 lumens has three modes and a tight 5-degree beam. Depending on the mode, the burn times range from 7.5hrs to 72hrs.

With the beam angle of 5 degrees high luminous intensity in the spot and wide bounded halo, this is the best choice for divers demanding the optimised light beam.

A bright spot illuminates the object, while a halo gives light to the surroundings, shines through the murky water, and is convenient for effective signalling.

A wide-bounded halo of Finn Light 2500 XLong lets you know where you are. It illuminates the space in front of you without blinding your dive buddy.

Three light modes

Variable 3-mode power levels allow you to customise the light output and burn time.

The first turn of the magnetic ring in any direction switches the light to 250-lumen mode, which can be used on the surface safely.

Another turn in a clockwise direction switches the light into the half-power 1250 lumen, which is excellent in murky water.

The third turn with the magnetic rings starts the full power mode, producing a brilliant 2500-lumen tight beam.

Finn Light 2500 optics

Finn Light 2500 is equipped with one single LED 2500 lumen, providing cold white light and 10,000 hours of permanent usage. The optimised light beam gives the angle +/- 5° and a clear center spot for effective signalling.

Finn Light 2500 XLong design and materials

The casing is made of heat-treated aluminium alloy resistant to corrosion and salt water. The surface is anodised with a hard eloxal coating that is very durable and resistant to abrasion.

The magnetic ring stops in accurately defined positions when changing the light modes.

The robustness of the light construction determines the usage in extreme conditions.
