The System Nicola Mk 2 has been in operation for a good many years in the south of France, and now the designer, Graham Naylor, is pressing on with a completely digital version, the Mk3. UK Cave Rescue Teams have been using the Heyphone since 2001. In 2004, Beat Heeb designed a mobile phone sized device for sending and receiving text messages underground. Both the Nicola Mk 2 and the "mobile texter" have ranges of ~1000m, I can't remember what the operating range of the Heyphone is.

Looks like the designer had just finished watching Men In Black...
