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.

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 Heated Vest Combo includes the Santi Heating Vest Flex 2.0, Santi 9Ah Blue Power Battery and Drysuit Connector or Thermovalve. All in a neat package - ready to go.

The Santi Heated Vest Flex 2.0 is perfect for divers who need more insulation than can be provided by 'passive' undersuits. The Santi Heating Vest actually actively helps to keep you warm, it is not designed to warm you up but to limit the rate at which you become cold. As such the heating vest does not feel 'hot' but it's effects can be felt.

Santi Heated Vest Flex 2.0

The Santi Heated Vest Flex 2.0 was designed to provide the highest functionality and safety. Thanks to the fabric used, the vest provides thermal comfort even when a battery is not used.

Made of very flexible Climashield insulation fabric weighing 180g/m2, it consists of three layers – breathable Climashield Contour insulation covered with two protective layers made of polyester from the inside and outside. The external layer also has windproof properties.

The newest version of the Santi Heated Vest, thanks to new, non-quilted fabric quality, provides more warmth towards the body. It generates better thermal properties and keeps the heat trapped closer to the body for longer.

The sides and crotch strap of the vest feature wide elastic bands to allow the best adjustments.

The Heated Vest can be used directly over a thinsulate or 'sandwiched' between a thinsulate and baselayer to capture and spread heat proportionally.

  • Handy pocket for power cord
  • P-valve hose opening
  • Wires covered with ultra-soft silicone isolation resistant to breaking
  • Power cable resistant to high temperatures and cuts
  • Power cable hidden in a handy pocket
  • Ergonomic nesting and wires layout inside
  • Weight: 180g/m2, isolation: 0.96 CLO
  • Maximum heating temperature: 45ºC
  • Maximum heating power: 55W
  • Safety switch preventing from overheating and too strong current

Thermovalve or Drysuit Connector?

Both the Santi Thermovalve 303 and the Drysuit Connector are used to connect an external power source to your Santi heated vest, heated gloves or heated undersuit. Both are available in Apeks or SiTech fittings.

The SANTI Drysuit Connector does this by being attached to your existing drysuit inflation valve, continuing to use the original valve for inflation and running power through the connector element. It adds 19mm height to your valve.

Thermovalve 303’s great advantage is placing the cable with the E/O connector in the down position, with the possibility of turning the head by 270 degrees, which allows for trouble-free connection of the hopper cable both in the position of the connector to the right and left.
