Underwater Explorers is a leading UK Technical Diving Facility as well as the country's first dive centre with training devoted to "Hogarthian" diving, expressed in safe and simple kit configuration, using only non-narcotic gases with best properties for any given depth, always working within a Team environment... and rejecting the concepts of "deep air" and "solo" diving both in training and activities.

We believe that "less if more in diving" and have an open mind towards all kit configurations.

For any enquiries relating to the TDI Extended Range course please contact us directly. All ER skills are covered in our Decompression Procedures and Trimix courses. See our Team.
