Features:This product is made of high quality material; strong and durable.Detect pinhole camera: Press the switch button to turn on the detector; the back of the 6 lasers starts to flash; hold the long press for 2 seconds to change the laser flicker frequency once; release the switch to select the desired flicker frequency; there are 8 levels; observe the surrounding environment through the window; if the detection The lens to the pinhole camera will reflect a red dot.Detecting cell phone signals: At the point where you need to detect; or you can find an object; such as a car; you can first find a place where there is no signal or the wireless signal is weak. Start the sensitivity adjustment switch to the maximum; and the strong vibration of the machine will slowly decrease in the opposite direction. The sensitivity switch to the shock just stops; and the sensitivity of the machine is the best initial test state in the field. If a wireless signal is detected; the machine award will vibrate or beep. When the signal becomes strong; the indicator bar is fully illuminated; and the antenna is gradually shortened; and the small sensitivity switch is slowly reversed to reduce the frame measurement range; and finally the emission can be found. signal source.Detecting strong magnetic signal sources: Magnetic Locator; the detector is mostly used in cars; and the in&nbsp;test is placed. The detection distance of the strong magnetic probe is within 5-10%. It is recommended to place the strong magnetic probe close to the inside of the car; the bottom of the car; or after opening the front and rear covers of the car. The area of detection; the gridded close-range exploration; can easily find strong magnetic adsorption equipment.Full-band multi-function signal detection.
