1. Product introduction:
The 511 metal detector can be used to search for explosives, firearms, knives, etc. buried in the ground, water and buildings in international peacekeeping, counter-terrorism and security inspection operations, and provide accurate information for the removal of dangerous items. It can also be used to detect various mines or unexploded ordnance buried under the ground in mine detection and clearance operations during and after the war.
The detector innovatively uses multi-time-wide bipolar pulse electromagnetic induction technology and soil background automatic balance technology, and has achieved breakthroughs in detection sensitivity and soil adaptability, representing the latest achievements of our army‘s metal detection equipment.

2. System composition:
The whole set of equipment consists of detector, external battery compartment, charger, battery, calibration kit, backpack, carrying case, etc.
The detector consists of a probe, a probe rod, a handle, an arm sleeve, a host and a headset. The length of the probe rod can be continuously adjusted to meet the requirements of various detection postures; buttons and LED warning lights are set on the handle, and the operator can adjust the system functions through the buttons, and observe the current alarm status of the equipment through the LED; the equipment can use the built-in battery of the host Or two power supply modes of external battery compartment. When the ambient temperature is too low, the external battery can be kept warm with the help of the body to ensure the normal operation of the device. The external battery compartment can also reduce the load on the arm and reduce the intensity of the detection operation.
