“The 7th Edition of the Commercial Diver Training Manual continues to fill the gap between

learning through field experience and learning through entry-level commercial diver training.

Our commercial diving students and graduates have been well served since 2016 by the

author’s meticulous and thorough approach to making vast field experiences and safety come

alive in the 6 th Edition, and once again in this revised 7th edition. It continues to be a leading

textbook in our training, due to its technical accuracy, current content, photos, and

illustrations.

Safety and efficiency are pinnacle traits that any successful working diver must learn in their

training and constantly apply in the field. Safety is not a simply a rule book, it is a state of

mind. Hal Lomax’s approach to this and sharing his knowledge with all levels of divers has made our industry safer and advanced it entirely.

At the very core of commercial diver training are two essential objectives: Going up and down

in the water column safely and performing useful and effective work underwater. This textbook

continues to provide both objectives into a current and well written resource for the entire

industry. It remains a must for anyone’s library involved in commercial diving.”
