Technically Speaking is the latest book from best-selling Scuba series author Simon Pridmore. It is a selection of themed talks telling the early history of technical diving—where it came from, how it developed, how it expanded across the world, who the important movers were and how, in the decade from 1989 to 1999, the efforts of a few determined people changed scuba diving forever.

Simon Pridmore's aim in writing this book was to examine and record where technical diving came from, how it developed, how it expanded across the world, who the important movers were and how the efforts of a few determined people changed our little field of human endeavour forever.
