Main features: 

1,a balance between the lines, to eliminate "mineralization response" to the effect of greatly increasing the effective detection of the depth and accuracy: 

2, a difference between black metal and non-ferrous metals function;

3,operating system using the smart use of high-intensity ABC packaging materials, light weight, long life 

4, can be identified through headphones sound of metal products parameters: 

5,maximum depth of exploration: small capitalization 1.5 meters, 3.5 meters market signal frequency: 7 KHz 

6,audio frequency: 400 Hz current work: 12 DCV "AA" (alkaline) 8X1.5V 

7, power consumption: 0.6 W Weight: 3.2 Kg

This product using voice alarm and instrumentation, with the probing depth exploration of metal the size, shape, weight, have great relations, in general, the greater area, the more, the corresponding detection greater depth the contrary, The smaller the area, the fewer the number, the smaller the corresponding depth.  The following table lists the most probing depth, the enterprise is based on standard products with a 60 cm * 60 cm by 0.5 cm * Aluminium buried in the dry soil of the measured results.
