High accuracy deep metal detector for 3.5m underground

MD-91 Applications:
1.Safety inspection;
2.Criminal department to quickly search;
3.Metal raw materials, fuel, food in the detection;
4.Metal objects check mail, parcel in the;
5.Pipeline, the exploration of underground cable;
6.Archaeology, exploration;
7.Found buried in the underground treasures of gold and silver and metal artifacts
Features:
1.The shell is made of high strength ABS engineering plastic, has the advantages of high strength, light weight, long life;
2.Can effectively distinguish accurately ferrous and non-ferrous metal function;
3.A balanced line, can eliminate the influence of "mineralization reaction" to bring, effectively improve the detecting depth and accuracy;
4.Having less pressure alarm device;
5.The rechargeable battery repetitive work;
6.Through speakers or headphones detecting metallic sound.
