Uses
Metal detectors can be used to find many items and products, such as coin shooting, treasure hunting, saltwater beaches hunting, and almost everything containing a significant amount of metals.
They can be used in parks by children, in your home to look for some lost item, at salt water beaches to look for the gold nugget, in iron trash and in junkyards to find valuables.
Entry-level
For beginners looking to dip their feet in the world of metal detecting, they would start with a simple, easy-to-use detector with minimal features that can work on dry sand and help you get the hang of things.
Buying a complicated piece of equipment can not only make your life difficult while understanding the confusing features, and it can also put you off from the hobby.
Relic Hunting
If you’re a Civil War relic hunter, you should know that relic hunting uses detectors that are quite high-tech. These units use a variety of modern tech to scan beneath the ground to detect images of the relics. They usually have larger coils. You should invest in a good quality digital imaging detector with a low-frequency machine for relic hunting.
Multi-Frequency
These metal detectors are also loaded with high-tech features, and they use multiple operating frequencies to detect a particular object. This feature makes the detectors target the search area better. Aside from that, there are low-frequency machines known as VLF detectors, they transmit a single frequency in the range of 5.5 KHz. This can be used by a bounty hunter or a beginner detectorist on playgrounds or in freshwater streams as they contain less salt content
Pulse Induction
PI detectors are different from usual detectors because they have a single for transmitting and receiving signals. The pulse induction machine is most commonly used for finding gold nuggets in shallow saltwater rivers. Since they are used for underwater detection, PI machines tend to be heavy.
Waterproof
Most modern metal detectors are waterproof, but there’s a catch. Most of the time, it’s just the waterproof coil, meaning you can’t use the entire system near or underwater activities like scuba diving.
If you want a detector kit suitable for underwater use, you should look for those specified underwater at a specified depth.
If you seek a metal detector for the beach, go for waterproof pulse induction machines or a very low frequency (VLF) detector.
