Here you can find metal detectors features and technical specifications (click on the icon).

Metal detecting can be split into three main categories:

  • Coin Shooting – hunting out beaches and or parks for valuables including decimal coins, jewellery.
  • Relic hunting – Hunting historical grounds such as old homesteads, cemeteries, +100 year old parks. In search of historical valuables e.g. Gold sovereigns, Silver florins, Pre-decimal coins, Buried treasure.
  • Gold Prospecting – This type of metal detecting is popular in Australia and some areas of the US.

There are 3 main types of detector all of which comprise of 4 basic parts:

  • The search coil which is the lowest part and it transmits and receives the signals into the ground
  • The Control Box for switching on and off and where the search coil signals are relayed back to you these can be audio or visual depending on the detector that you are using
  • The Shaft which connects the control box and search coil
  • The Stabiliser at the top to make it easier to sweep in a balanced fashion

Metal detectors use one of three technologies:

  • BFO (Beat Frequent Oscillation) – This type is the most popular being simple to use and cheaper than the other two types. It has two coils which create pulses resulting in radio waves being bounced into the ground. The control box monitors any changes in the returning pulses. This is the type that is recommended to use and favoured by most users.
  • PI (Pulse Induction) – Uses only a single coil and is recommended in a salt water environment
  • VLF (Very Low Frequency) – This has two coils each with its own function one is a transmitter while the other is a receiver and this detector is best at identifying different types of metals.

Metal Detecting Tips

What sort of metal detector is best for a beginner?

There is no need for beginner prospectors to buy an expensive top-end machine. We advise starting with a simple base model. The main advantage is that these models are easy to operate and easy to learn, as well as being cheaper. Prospectors can upgrade later if they find they want to expand their options.

What type of coils can I get for my machine?

Metal detectors can be fitted with a range of after-market coils. These coils provide more options for prospecting, such as providing the ability to search at greater depth. They can also provide improved sensitivity. We advise first determining what you want your coil to do and then finding the right coil for the job. The right advice is important here.

Why am I getting a false signal?

This can be a simple matter to fix. Often a build-up of dust and dirt will accumulate between the coil protector cover and the coil itself. This will stick to the coils, particularly if it gets damp. The minerals in the attached dirt will register a false signal. Take the cover off then give it and the coils a good clean. Often this is enough to fix the problem.

Where is the best place for prospecting?

Some of the best places to be a treasure hunter are areas which are used by people or were inhabited in the past. Places that have gone like Fort Sites, Ghost Towns, Sites of early industry and Battle Sites can have buried forgotten treasure. Research old maps and newspapers of your area to see if any interesting places are close to you also approach any historical societies that may be in the area. The internet is also a great place to research history of a specific area. Places still used are full of undiscovered items from the past to recently lost items. Some examples are beaches, parks, camping parks, rest areas, tourist view points anywhere people can be found.

Which Metal Detector to buy this year?

Before purchasing think about where and the environment in which you would be using your detector especially if it’s in water. Another thing to consider is the length of time you intend to operate the detector as battery life can vary between the different models available
