JEOTECH is produced using the latest Macro technologies. Experience the first of a new generation of coin hunting detectors. From indivudual targets to deeply buried treasure caches, the JEOTECH can locate treasures beyond the reach of most ordinary detectors. The JEOTECH is designed to locate deeply buried Gold and precious metals. This model is also capable of detecting underground cavities and voids like tunnels, graves, caves and cellars. Powerful and deep detection capabilities allow the JEOTECH to easily detect targets even in the most mineralized ground conditions. Now you can locate those precious metals and deep cavities that others have missed! Unique to the JEOTECH is the capability to provide easy working conditions in highly mineralized environments. Locate targets underneath stones that contain metal. The revolutionary JEOTECH performs searches deeper than other systems produced for locating single coins. JEOTECH can simultaneously detect cavities such as caves, cellars and tunnels. It will locate precious metals with perfect accuracy. JEOTECH indicates Metal and Cavity detection to the user visually through the LEDs that are on the right and left side of the joystick. It will also produce unique audio tones. When JEOTECH detects a metal, it gives an audio signal and the METAL and MINERAL LEDs blink on the right side of the joystick. The response is based on the signal power of the target. When a cavity is detected, the CAVITY AND MINERAL LEDs blink on the left side of the joystick based on the signal power of the target. An audio signal is also produced. JEOTECH performs metal discrimination and analysis through the scanning key. If the target is a non-ferrous metal such as gold, silver, copper, bronze, etc., the NON-FERROUS LED will light. If the target is steel or iron, the FERROUS LED will illuminate to inform the user.
