Treasure hunter ‘ziggyjinx’ conducts really proper depth tests. With highly mineralized soil taken, and apart from usual measurements, there are also tests where a coin is located near the iron. See, here’s a proper depth test of the Makro Racer 2.
All about the Makro Racer 2 metal detector is collected here (news, videos, tests, comparisons), and on Knowledgebase pages (specs, features, search coils, manual). Good finds to everyone!
