Jeohunter 3D Dual System is designed and manufactured using the latest technologies. This system is the World's most advanced detector for locating precious metals and detecting hidden cavities. Jeohunter 3D Dual System is a deep penetrating detector. The system uses advanced discrimination to accurately classify metal targets in to four groups: Gold, Non-ferrous, Steel and Iron. In addition to accurately detecting and analyzing metal objects, Jeohunter 3D Dual System is also capable of detecting cavities underground like caves, cellars, tunnels, shelters and graves in real time. Jeohunter 3D Dual System is the most advanced graphical imaging system, capable of drawing 2D signal graphs of detected targets in real time. The multifunctional search and detection features allow the user to search comfortably even in very highly mineralized ground conditions. Professional and amateur users alike will appreciate the friendly user interface. Unlike other detectors, Jeohunter 3D Dual System features easy to understand search screens. Jeohunter 3D Dual System provides a complete analysis of the buried target before you dig. The system provides exceptional depth, perfect metal discrimination and an accurate analysis of the target depth and size. Jeohunter 3D Dual System displays the depth of the target to the user in centimeters for both large and small targets. The system provides this same depth analysis for both metal targets and cavities. Jeohunter 3D Dual System is a complete metal detection system. The system comes with 3 different search coils. It is like owning three detectors in one. The 100 x 60 cm (24'' x 39'') Deep Search Coil is ideal for metals that have been underground for a long time and have created a magnetic field (oxidization) around them. The 36 x 44 cm (14'' x 17'') General Search Coil is for general purpose use. Finally, the 21 x 31,5cm (8.5'' x 12'') Small Search coil ideal for coins and for use in enclosed spaces such as cellars. Experience the thrill of reaching depths and discovering treasures that no one has ever reached.
