Book Review: Diving Equipment – Choice, Maintenance and Function
The Author
Jonas Arvidsson
Review by Jeff Goodman
First thing I have to say about this book is that every sports diver should have one.
In the past, diving manuals would often leave me cold and I would keep asking myself, do I really need to know all this? I wonder how many of us have had conversations about diving equipment, what to choose and how it works, without really knowing 100% what we were talking about. Please tell me I’m not the only one. This book ends all that with a very comprehensive table of contents and index, all fully supported by clear, precise and colourful graphics.
For many scuba divers, after their basic training is completed, they will happily buy, hire or borrow equipment to explore the underwater world. They often do this with absolute blind trust in the manufacturer, the salesman or the friend who has lent it. It is extraordinary really. This equipment is literally maintaining your life while you are underwater.
This well written and easy to understand book takes the reader through what each bit of equipment is for, how to choose what is best for you and how it works, from free diving and snorkelling right through to scuba and technical diving.
This book covers the options of cold water and tropical diving and looks closely at the different gear needed for each environment.
There is far too much in this book to cover in this short review but I’m sure that if you have a question about choosing your equipment and how to look after it then this publication is a must.
Diving gear is not cheap and can become a serious investment, so knowing what to choose and how best to ensure its long and reliable life is to my mind definitely worth the cost of this book.

Paul Watson Released as Denmark Blocks Japan’s Extradition Bid
Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.
