Features High accuracy: can identify certain types of metal using the frequency controller. The metal detector has a remote search system and an accurate position detection system. In addition, the detection range up to 800 m and the underground detection depth can be approx. amount High Performance The underground metal detector is made of aluminum alloy, which is durable, safe, easy to use and has a long service life. With a transmission frequency of 5.6 to 6 kHz and a signal frequency of 360 to 440 MHz, you can check more with the metal detector Premium design: microelectronic processor control chip calibration and instrument self-inspection system, which can scan and test conveniently and quickly, improve the work efficiency in treasure hunting and reduce the test effort. The metal d Wide usage: can hold various metals such as gold, silver, copper, stones, etc. so you can easily find the metal objects useful for you and accurately determine the position of the objects. Easy to carry: thanks to its light weight and compact size, the metal detector is very easy to use and suitable for outdoor use. Specification: Item Type:Metal Detector Detection depth: approx. 14 m / 45.93 feet. Note: This instrument can detect an object of 5 x 5 cm at least 3.5 m away. With an object of 30 x 30 cm, it can detect 5-8 meters wide, and if an object of this size is buried for a long time, it can reach up to 14 m. When the area of an object is larger, its detection depth becomes greater. Function: It can accurately detect the burial position of objects and locate them. It can also resort to frequency controllers to identify certain types of metals. Search system: microcomputer processor control and reflection conductivity Search range: approx. 800 m/2624.67 feet. Transmitter battery: 1 x 9V 6F22 battery, battery not included. Receiver battery: 1 x 9V 6F22 battery, battery not included. Signal Frequency: 360-440MHz Detection type: for gold, silver, copper, stone, etc. Package list: 1 x transmitter, 1 x receiver, 1 x user manual (English language not guaranteed) Package List 1 x Transmitter 1 x Receiver 1 x User Manual
