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.

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 BZ400 Extreme Undersuit Combo Set includes the Santi Heating BZ400 Undersuit, Santi Blue Power 28Ah Battery and Drysuit Connector or Thermovalve. All in a neat package - ready to go.

Santi BZ400 Extreme Heated Undersuit

Santi BZ400 Extreme Heated Undersuit is designed to comprehensively protect the whole body of a diver from the cold. The heated undersuit heats the trunk, thighs and arms evenly.

The BZ400 Extreme Heated Undersuit is designed to be worn on top of a thin base layer allowing most of the generated heat to be passed directly to the diver’s body.

The heated Santi undersuit gives you the best thermal protection underwater. It keeps you warm and comfortable while heating, even when the batteries are low or completely drained.

The new generation of heating wire is covered with ultra-soft, silicone isolation resistant to breaking. Innovative, synthetic power cable is resistant to high temperatures and cuts.

  • Operating time on 28Ah battery: approx. 3hrs
  • Made of BZ400 (420g/m2) Thinsulate™
  • Built in heating glove wires

FREE "Made to Fit" service

Very few divers require a totally made to measure suit due to the wide range of standard sizes available from Santi Diving. With this in mind, Santi offers a free of charge Made-to-Fit service to any standard Santi BZ400X Undersuit ordered, sculpting standard suits to a divers' measurements.

With your Santi BZ400 Extreme Heated Undersuit Combo order, you can request up to 4 changes (ranging from 2 to 5 cm) to any of the standard size measurements listed under chest, inner arm, biceps, forearm, waist, hips, inner leg, thigh, calf or body trunk on the Santi size chart.

If you would require more than 4 changes to make your suit perfect, you can add two more changes for a small additional charge.

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.

Santi Blue Power Battery

The Santi Blue Power Battery Large - 28Ah marks the beginning of a new generation of batteries dedicated to the Santi heating system(s) with double the power of the new Blue Power Medium 14Ah battery.

Uniting modern technology and contemporary electronics, the Santi Blue Power battery will allow you to enjoy uninterrupted and unflagging heat comfort over time.

With its two settings, the Santi Blue Power battery allows 2 levels of heating and independent, non-invasive (field) replacement of the power cable if necessary.

The difference

Several important features distinguish the Santi Blue Power battery from other batteries available on the market:

  • The ability to maintain a stable voltage level, thus maintaining a constant heating temperature throughout the battery's run time during a dive.
  • Two levels of constant voltage output set by the user as needed: (1) For typical heating power needed - Operated at 11V; (2) For higher heating power needed - Operated at 12V
  • A new ergonomic design of the E/O cord connector with two LEDs  
  • Audible and luminous indication of the battery mode along with an indication of low charge level.
  • Anti-slip casing and ergonomic shape are particularly useful on the surface.
  • The possibility of simple field replacement of the E/O cord cable in the selected length without having to send it for service.
  • A new failure-free piezoelectric button.

Maximum operating times

  • Santi Heated undersuit (110W): 3h
  • Santi Heated vest (55W): 6h
  • Santi Heated gloves (36W): 10h
  • Santi Heated undersuit with gloves (146W): 2h 20min
  • Santi Heated vest with gloves (91W): 3h 30min

What does the value represented in watt-hours mean?

Santi Blue Power batteries are available in two capacities, medium (14Ah) and large (28Ah).

In the case of the 198Wh Blue Power Medium 14Ah Battery setting the diver will have 198W of power to use in one hour. The diver will have 99W to use in two hours, and in four hours, about 45W.

Example 1:
Santi's heating vest has 55W + heating gloves 36W - a total of 91W. So 198Wh with a 14Ah battery will allow the equipment to be used for: 198Wh / 91W = 2.17h or about 2 hours and 10 minutes.

Example 2:
The heating gloves have 36W. So 397Wh with Blue Power Large 28Ah will allow heating gloves for: 397 Wh / 36W = 11.02h or about 11 hours.

The above result is also affected by the temperature at which the battery operates.

What systems can the Santi Blue Power battery be used for?

Whichever one of the two batteries you use, the Santi Blue Power battery is dedicated only to powering the Santi heating system components. The technology used in the batteries is not compatible with other devices.
