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.

Suex Sinapsi is a special nose for navigation that replaces the standard Suex scooter nose. It has sophisticated electronics to receive and process underwater navigation data acquired via DPV.

The Sinapsi project has required years of increasingly sophisticated research, including many tests and trials to optimise the system using the most exciting, up-to-date technological solutions.

Sinapsi is available for the Suex XJ-S and XK scooters.

The integrated propeller into the system allows you to calculate the speed and, consequently, the distance travelled or missing to the point of arrival.

Suex Sinapsi features

  • Route planning via smartphone app and PC
  • Use GNSS Position – Home Position
  • Dead Reckoning
  • On-the-fly route planning
  • Heading quality index
  • Compass calibration and quality storage
  • Odometer calibration and distance and speed measurement
  • Accurate heading angle
  • Data reception
  • Wireless system

Connection with Suex ERON-D1

The Suex Sinapsi nose cannot be used without a Suex ERON D-1. The ERON D-1 is the necessary user interface to access most Sinapsi functions and settings.

Used in conjunction with the ERON D-1 underwater dashboard, Suex Sinapsi is able to provide the customer with the most accurate underwater navigation. During operation, the Sinapsi nose transmits the navigation data to the ERON D-1, via a wireless connection, and the telemetry data from the scooter. Finally, it also records the data of the scooter battery together with the navigation data.

From a conceptual point of view, Suex Sinapsi exploits the potential of the AHRS system (Altitude and heading reference system) and GPS (Global Positioning System) to determine the current position of the scooter at all times.

It indicates that an operative procedure, a condition etc. must be pointed out.  From the physical operating point, the AHRS processes signals from the three main physical systems mounted on board:

  • Compass
  • Gyroscope
  • Distance log

DPVs equipped with Suex Sinapsi and ERON D-1 can access the extended mode of the dashboard: recording of dive time, depth, heading and other data, full analysis of DPV data and full navigation data.
