Feature: 1. ACCURATE DETECTION: Metal detectors can locate objects by accurately determining where they are buried. It can also rely on the frequency regulator to identify the specific type of metal. 2. SENSITIVE AND STABLE: The metal detectors has excellent sensitivity and stability, intelligent modularization, powerful operation and high efficiency. Simple operation, easy to use. 3. MICROCOMPUTER CONTROL CHIP: Metal scanner device adopts microcomputer control chip unit calibration, the instrument, self checking system can be quickly and easily scanned and detected. 4. IMPROVE EFFICIENCY: Metal detectors is the most advanced and practical detection method at present. It greatly improves the working efficiency of geocache enthusiasts and reduces the labor strength of detection. 5. SUPERIOR PERFORMANCE: The detection method of this kind of metal detectors breaks through the traditional detection method, with superior remote search system and precise positioning detection system.
