Introduction of Very Low-Frequency Metal Detectors

This is one of the most popular metal detectors currently in use. This is especially so among experienced treasure seekers. The detector can be highly accurate and sensitive. This coil also has a pair of coils, which work together. The first coil is the transmitter, usually giving off an intense electric current. The second coil is a receiver; it picks the signal from the main coil and amplifies it many times over.

The transmitter coil works by looping a magnetic field above and below ground. This field usually extends about two feet into the ground. The field usually stays that way until it comes across a metal object. When this happens, the object develops a magnetic current. This current then interferes with the perfect magnetic loop running into the ground. Thus, the secondary coil picks up the interference. This coil magnifies and sends into an audio system attached to the Metal Detector. Thus, the person is able to tell if there is an object in the ground. The beauty about this detector is that each metal objector generates a different frequency.

Highly magnetic objects such as steel or iron generate a very power field. This field is quite distinct and some detectors have the technology to indicate this. As a result, one does not waste endless hours digging up worthless objects. In addition, it can detect objects with a very low magnetic pulse. This includes precious objects such as gold. Ultimately, this is the aim of buying a metal detector. As a result, it would be self-defeating not to invest in such a good metal detector. With this type of metal detector, one has a higher chance of discovering precious stuff buried underground.

Junhong company has many models of Underground Metal Detector, like GF2 and FS2 underground metal detector.
