This detector is pretty good, it really makes a good sound when it detects something. make a noise Really loud. This is a very accurate fast detection of electromagnetic fields. The charging performance is great, it has a wired charging cable, it also has a battery slot on the back if you need backup power. It also has an additional gift - a zipper and a magnet. Well worth the money I paid for. I wish I had more gifts in the future, kidding. Durable detector and also a good gift. For those who work in this field.
