This book is the result of many years of research by the author to create metal detectors of varying complexity and consists of two parts.
In the first part, various principles of the operation of metal detectors, their strengths and weaknesses are examined in detail, comparative characteristics are given, and theoretical models of sensor coils are described.
The second part of the book describes the practical designs of metal detectors developed by the author, or with his participation. All of these constructions are described in detail and can easily be repeated under conditions home laboratories.
At the end of the book are given the practical design of the sensors, the technology of their manufacture, their advantages and disadvantages, the features of their use are considered.
The book also provides the author’s correspondence with readers, where the author answers the most common questions. Answers are grouped by design.
The book will be of interest to a wide range of amateur radio enthusiasts, especially amateur radio enthusiasts who have no experience in building metal detectors.
