How can we help?

If you need to contact us for any issue or assistance, you can do so online by filling out the online Contact Form, emailing us at or calling us on +44(0)1305 824 555. If it's about a purchase you've made for us please also include your order number.

Our brick-and-mortar store Underwater Explorers based on Portland, Dorset is staffed 7 days a week, including weekends and bank holidays. As it's an active store visited by divers from around the country and world regularly, if we can't make it to the phone for any reason please leave a message and we'll get back to you asap.

Any queries are usually answered the very same day and at most within 24 hours.


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.

Reveal rich fluorescent colours with SeaLife Sea Dragon Fluoro Dual Beam Photo Light Set.

The Sea Dragon Fluoro-Dual Beam emits a powerful blue light beam and adds an integrated dichroic filter, creating the optimal light wavelength to “excite” underwater life.

Two switchable beams transform the versatile light from a blue fluoro 65° flood light to a white 800-lumen 15° concentrated beam with a push of a button.

A rechargeable Lithium Ion 7.4V, 3400 mAh, 25Wh battery delivers power for 60 minutes at 100% fluoro emission. With its single-button operation, the light can quickly adjust between four brightness modes: 100% fluoro flood, 50% fluoro flood, 100% white spot, and 50% white spot. Depth rated down to 100m.

With their filter, the Sea Dragon Fluoro-Dual Beam’s Royal blue LEDs emit blue light in the range of 450-460nm; the wavelength to “excite” the fish, plants or organisms into making a light-filled energy response. The finely tuned and proprietary dichroic filter pinpoints the exact light wavelength to get the highest energy response from the underwater subjects.

Enhance your underwater fluoro-viewing

Two universal barrier filters are included to improve your experience in underwater fluorescent viewing and imaging. The mask filter fits over the dive mask to filter out the residual presence of blue light emitted by the light (it’s the response from the sea creature you want to see, not the blue light). The second filter attaches to any underwater camera with a lens diameter of up to 47mm.

Fluoro Dual Beam features

  • Switchable dual beams feature six CREE XT-E Royal Blue LEDs with a proprietary dichroic filter (light wavelength 450-460nm) flood beam and one CREE XP-L LED white spot beam.
  • 65° fluorescent wide angle beam and 15° white spot beam angle evenly illuminate the subject with no hot spots.
  • One button control for easy operation – one button to power the light on/off and select brightness.
  • Four brightness levels: 100% fluoro flood, 50% fluoro flood,100% white spot, and 50% white spot.
  • Hidden emergency signal mode: 1-second blink interval and SOS Morse code.
  • 60-minute run time at full power and constant brightness.
  • Depth rated to 330 feet/100 meters.
  • Easy to expand with Flex-Connect™ trays, grips and Flex Arms, handle, Y-S, ball joint, cold shoe and other accessories.
  • Quick-release button to detach light and aim in crevices and hard-to-reach areas.
  • Includes integrated dichroic filter and two universal barrier filters for your dive mask and camera for optimal fluoro viewing and photography.
  • Corrosion-proof metal light head for heat dispersion and durability.
  • Removable 25W Li-Ion battery w/ charger and international plug adapters included.
  • Waterproof battery compartment – even if the O-ring seal fails, the battery compartment is isolated so water cannot reach the internal electronics.
  • Universal mounting screw fits SeaLife and other brands of underwater cameras w/ standard ¼-20 tripod mount.
  • Protective circuitry – The light and battery feature integrated protective circuits that cut power in the unlikely event the light overheats or short circuits.
  • Safety pressure release valve – a one-way waterproof valve releases battery compartment pressure in the unlikely event of battery malfunction.

SeaLife Sea Dragon Fluoro vs. Harmful UV lights

For BEST results and SAFETY reasons, the Sea Dragon Fluoro-Dual Beam uses Cree Royal Blue LEDs combined with a proprietary dichroic filter.  SeaLife NEVER has and never will use Ultraviolet (UV) LED’s.

Some companies are selling underwater UV lights, claiming the results are better than blue LED’s, and that there is no need for a yellow barrier filter over your mask and/or camera. The truth is that UV lights pose a serious safety hazard to the eyes of humans and sea creatures. UV light is invisible, so you don’t realise your eye is bombarded with UV rays. It is a proven fact that extended exposure to UV light has been linked to eye damage, including cataracts, macular degeneration, pingueculae, pterygia and photokeratitis, which can cause temporary vision loss.

The Sea Dragon Fluoro-Dual beam’s Blue LED’s, combined with an exclusive dichroic filter, emits a powerful blue light, creating the optimal wavelength to excite underwater organisms. To see the fluorescence effect best, two yellow barrier filters are included – one for your mask and another for your camera. The primary purpose of the yellow filters is to absorb the visible excess blue light, so you only see the fluorescence effect.

Underwater testing shows that more sea creatures fluoresce when exposed to the Sea Dragon Fluoro-Dual Beam compared to UV lights.
