Richard Devanney is a multi-agency technical instructor based in Reykjavik, Iceland. He works for Magmadive, which recently became the first TDI dive center in Iceland. Magmadive specialises in multi-day technical exploration/fun dives all over Iceland. He also teaches TDI/SDI courses in some of the strangest underwater environments on earth; deco diving at the only hydrothermal vent in the world shallow enough to dive, or geothermal springs where you can feel hydrogen sulphide bubbles vibrating your entire body as they rise through a lake-bed!).
He also runs a Facebook technical diving information page called Iceland Technical Diving. You can contact him at email@example.com or firstname.lastname@example.org
