1. This machine has two detection modes: wireless signal detection and strong magnetic detection. Through its high sensitivity and super anti-interference ability, it can accurately detect various eavesdropping devices, GPS locators and 2G /3G/4G signal SIM number, and can detect CDMA signals, and this function is not available in other detectors.2. The design of this machine is small and light, and it can be easily controlled by a few keys. When a suspicious wireless signal or strong radiation source is found, it will beep or vibrate, and the closer to the suspicious signal, the more urgent the alarm will be.3. This machine adopts a high-sensitivity chip, which increases the exploration range and broadens the exploration frequency. The detection frequency range can reach 1MHz-6.5GHz, so that illegal devices such as bugging devices and GPS locators can't hide.4. It can detect radiation sources and keep you away from radiation, thereby protecting the health of you and your family.5. Widely used, you can use it at home, hotel, bathroom, changing room, office, important workshop, research room, meeting room, etc., to protect your privacy to the greatest extent.Product parameters:Frequency range: 1-6500MHZDetection dynamic range: >73dbDetection sensitivity:
