Discover the underwater world on a single breath with Adventure Freediving, a practical and highly illustrated guide to recreational freediving, open-water exploration and safer breath-hold diving.


Designed for beginners and developing freedivers, this book explains the essential concepts behind freediving in clear, accessible language. It covers how the body responds to breath-holding, breathing and recovery, pressure and equalisation, equipment selection, open-water technique, buddy procedures and emergency awareness. These subjects form the core progression of the guide.


Throughout the book, original diagrams and illustrations help explain concepts that are often difficult to understand from text alone, including gas exchange, buoyancy, equalisation, duck diving, efficient underwater movement, wildlife encounters, buddy supervision and surface recovery.


The guide places particular emphasis on responsible recreational freediving. Freediving allows people to explore reefs, observe marine wildlife and move underwater without artificial breathing equipment, but it requires appropriate knowledge, preparation and safety procedures.

Inside the book


You will learn about:

  • Freediving fundamentals and the main breath-hold disciplines
  • How oxygen and carbon dioxide behave during apnea
  • The mammalian diving response
  • Relaxed breathing and preparation before a dive
  • Safe surface recovery after breath-hold diving
  • Pressure, Boyle's Law and equalisation
  • The ear, Eustachian tubes and common equalisation problems
  • Masks, snorkels, fins, wetsuits, weights, floats and dive computers
  • Buoyancy and weighting principles
  • Planning an open-water freediving session
  • Duck dives and economical underwater movement
  • Buddy procedures and underwater communication
  • Responsible encounters with marine wildlife
  • Recognising hypoxia and freediving emergencies
  • Emergency response principles and the importance of practical rescue and CPR training


The original material also stresses the importance of capable buddy supervision and describes blackout and loss of motor control as major freediving hazards.


Who is this book for?


Adventure Freediving is suitable for:

Beginners preparing for their first freediving experiences, snorkellers who want to develop stronger underwater skills, recreational freedivers interested in open-water exploration, underwater photographers and wildlife enthusiasts, and anyone wanting a clearer understanding of the physiology and safety principles behind breath-hold diving.

More than a depth or breath-hold manual


This is not a book about chasing records. Its focus is on understanding the underwater environment, making sensible decisions, moving efficiently and returning safely to the surface.


Whether your goal is exploring a Mediterranean reef, observing marine wildlife, improving your underwater photography or simply becoming more comfortable beneath the surface, Adventure Freediving provides an illustrated foundation for developing your knowledge.


Digital PDF edition.


Important: Freediving involves inherent risks, including loss of consciousness and drowning. This book is an educational resource and is not a substitute for practical instruction, supervised training, first-aid/CPR training or professional medical advice.
