Zero Visibility from Hinchcliffe Books is a new book with an exciting compilation of stories and light hearted personal accounts of deep commercial "mixed-gas" diving in the 1960's and beyond. It is about the divers who experienced and experimented with helium gas and other emerging diving technologies of that era.

Written by a commercial diver who was there, working in deep water construction, offshore oil and underwater salvage. This book will provide engrossing reading for the younger divers and commercial divers, whilst it will refresh many reminiscences for the older divers.
