Many people have heard the metal detector. But few people know the origin of it comes from the rapid development of industry. Because of the substantial increase in demand for metals that many scientists and engineers use their knowledge of electrical theory trying to design a way to help people looking for metal tools which is a in the 19th century.  This will bring a breakthrough in the development of mining and it will greatly facilitate the work of the miners. However, the invention of the first metal detector is to save lives. As early as in 1874, Paris, an inventor who was called Gustav tried to invent a handheld pointing device. He hoped that it could help the patient who is shot. Inspired by him, Alexander Graham Bell developed a similar device. He tried to find the Metal bullet at US President James Garfield's chest in 1881 .But unfortunately, at that time they had a really bad conditions and the lower accuracy of the detector can’t clearly distinguish the metal coil spring bed from metal bullets in President Garfield’s body. So the President finally died .But this invention was left as the origin of modern metal detectors.

Modern metal detectors are different from the old. They are more powerful and Multi-purpose. And the appearance and shape is also very diversification. And today we will see a special detector which can be operate in shallow water.

This high-precision waterproof ground search metal detectors have a simple way to identify the metal detector which can be used to search for metal objects in the ground. Based on high-brightness LED signals that it can show the type of the detected metal in general. Besides that, it can distinguish metal type by tones and the design of a 9.5-inch disk waterproof probe makes it has the ability to detect in the shallow water. This makes it different from other detectors. As for power, it has a built-in high-capacity rechargeable battery and a low voltage. When it is fully charged, it can work continuously for 10 hours!

So I call it A Metal Detector which can work in the water but not a fish. But it just works like a fish though it doesn’t look like it at all.
