Product Description

Under Ground Gold Metal Detector for mine detection

Introduction                                                                          

1). Fast and high efficiency:
Complete about 4000m profile measurement in one day to realize geological abnormality in different depth, the prospecting speed and efficiency is improved about 10 times more than traditional resistivity method.
2). Easy to carry:
Without heavy power supply, it uses low frequency signals in earth natural electric field as signal source, and the complete set weight is less than 5kg so easy to carry.
3). Easy operation:
User-friendly interface, high-speed CPU, menu prompts,. You can learn its operation in 2 minutes. It will take 2h for persons without prospecting experience to finish training.
4). Good precision and high accuracy:
With imported core parts, FFT digital filtering technology, high-performance amplifiers and AD converters, the resolution is up to 0.1uV±1%, and the fixed error of frequency is only 0.1%.
5). Wide frequency range:
The frequency respond range is from 0.1Hz to 5 KHz, to greatly improve the surveying depth.
6). Strong anti-jamming capability:
It has advanced anti-jamming technology and multiple anti-jamming designs. You can observe abnormity curves result with good repetition even in weak signal area, city, high electric jamming area and working area with other exterior interference via frequency selector and digital processing. 7). Flexible array-traditional and unique array method:
It applies much measurement method: fine and rough measurement, "Two-pole" profile, "Two-pole" sounding, Multi-frequency sounding and annulus profile etc., which has good geological effect and easy explanation. It makes big achievement in solving problems about the direction, depth and thickness of ore vein
8). Remarkable effect:
Through the relative physical parameters variation like different conductivity between ore and non-ore object, it can get the relative information as ore vein direction, buried depth, thickness and deposit etc. In more than 20 years' practice, we gained outstanding achievement and customers' common praise.
