{"product_id":"9788086167206","title":"Hledače kovů – Wilhelm Rolf (2003)","description":"\u003cp\u003eAfter the necessary first part describing the theoretical foundations and the second part dealing with the design of devices based on real detection conditions, the third part of the book follows, which is its core. It provides instructions for building a total of four detectors that differ in both the area of application and the complexity of construction and costs. There is a simple wire finder, followed by a balance detector, the next is a somewhat more complex VLF finder, and the last impulse metal detector is already on par with professional devices for the most demanding applications. You will not need any special and expensive tools or measuring instruments for the construction. The book contains schematics, mechanical plans of parts, component layouts, adjustment instructions, detailed guides for building special components (coils, high-performance detectors), and other related information and diagrams.\u003c\/p\u003e","brand":"Ing.
