Operating status:
1. Once fully charged, turn on the host detector, remove the antenna, turn on the sensor switch, press the button corresponding to the item to be detected by the sensor, and then adjust the depth and range search function of the host detector to detect;
2.When the handheld device is stable and free from interference, it will oscillate left and right when detecting the designated object.When the detected object is large, the amplitude of the oscillation will increase;
Power-on Test:
Turn on the switch between the host and the finder, and the finder's working indicator will flash; When gold equipment is selected on the host, the corresponding gold indicator on the finder will light up.When sequentially selecting other gears in silver, diamond, and gemstones on the host, the corresponding indicator light on the finder will illuminate.
If a gear is selected on the host but the corresponding indicator light on the finder is not illuminated, the host and finder may have insufficient battery power and need to be recharged.
If the above situation is normal, this indicates that the instrument is functioning correctly and can be used with confidence.

How to Use:Charging Method: This instrument has a built-in rechargeable battery and can be charged directly by connecting it to the charger. Charging time is 8 to 10 hours.
Package List:Package includes: 1 x Metal Detector with Display Screen
1 x Power Adapter
1 x Instruction Manual
Note:1. It is necessary to operate strictly in a jungle environment without interference and to maintain high stability; 2.The host and transmitter must be switched on and off simultaneously to be used for detection;
