Method 1: Because the false metal detector is made of permanent magnet steel, which means that the shape of the machine and equipment is similar to its principle and technology, the technology cannot be changed. After purchasing the machine, customers can use the simplest key to place it inside the detection probe, which is what we call the effective detection area. If the probe has an adsorption active wrench, it can be concluded that you have purchased a fake metal detector, because the real metal detector probe is composed of coils and fillers inside, and there is no shovel magnetic adsorption phenomenon when there is no current passing through or signal.
Method 2: Tear off a small piece of a cigarette box lined with tin foil for testing. A fake metal detector cannot detect this piece of tin foil, while a real metal detector can detect an alarm even if it is a small piece of tin foil, thus determining the authenticity of the metal detector.
Secondly, there is the price. Although the prices of metal detectors in shopping malls vary, the main price range is still not significantly different. If the product quotation is below 30-50% of this price range, then attention should be paid. After all, you get what you pay for, and the price is too low for metal detectors, which is basically impossible to be true.
