Metal detecting is becoming increasingly popular and many more people are starting to take it up as a hobby. Of course, for metal detecting, the most important piece of equipment you will need is a metal detector. However, picking the right one can be tough with so many on the market. Below we have made a list of the most important features to look for in a metal detector.
The size of your metal detector can affect how you use it. For example, a smaller coil will help in high trash areas where larger coils are recommended for deep searching. In terms of overall size, the handle and length of the metal detector should fit the user. If a child is using it, you will want it to be lighter for instance.
There are a range of frequencies for metal detectors. The most common is 5kHz – 25kHz per second, but some can go as high as 100kHz. Most serious metal detector users will want to get a higher frequency for better results.
Knowing your metal detector is finding the right things and what you are looking for can be hard. Many detectors make use of different modes and materials to ensure that they are durable and accurate when in operation. Things like audio discrimination, all-metal modes, and electronic pinpointing can make the reliability of your metal detector better so it's worth considering these before purchasing.
Metal detectors are often used in rugged landscapes that are exposed to water and weather elements. This makes waterproof detectors much more effective than other models when in use, as they can be used across many more landscapes. Some detectors also have waterproof coils which allow them to be used underwater, giving them an advantage over other models.
Ease of Use
Regardless of the detector you are going for, you will want to consider functionality and ergonomics. You may be out on the field for a while as a result of this, so having an easy-to-use LCD screen, comfortable handles, and lightweight aluminum can make it really convenient to use.
Types Of Metal Detectors
There are three main types of metal detectors. We have listed them below:
Very Low-Frequency Detectors:
There are two types of metal detectors: basic ones and advanced ones. The basic ones have 2 coils and work to reflect electromagnetic signals and find metals. They are usually lightweight and perfect for beginners or children. Their basic build, however, means that they do not detect as well as other types.
Pulse Induction Detectors:
They have just one coil. This means they are less affected by ground mineralization and therefore more accurate, however it makes them unable to discriminate between metals. This is especially true in urban areas where a lot of trash exists.
Most other types of detectors are specialty ones that are built for a certain purchase. This can be anything from solely gold detection to multi-frequency detectors. These are expensive and should be used by those serious about metal detecting.
Q: How do metal detectors work?
Ans: A metal detector is a device which detects the presence of metals. It works by sending out an electromagnetic field from the search coil in the ground and when it comes into contact with metal, the metals become energized and send out an electromagnetic current that activates the metal detector's alarm.
Q: What can a metal detector detect?
Ans: It comes as no surprise that metal detectors are used to detect metals of all kinds. These can range from a tin can to a golden ingot. Importantly, some detectors only have a range of detection on some metals and often can’t detect more precious metals. This is something to consider before purchasing one.
Q: How deep do metal detectors scan?
Ans: Most metal detectors can detect objects at about 4–8” deep. In ideal conditions, with the right detector and with extended search time this can sometimes be extended to 12-18” but generally it is surface-level detection.
Q: Can you keep what you find with a metal detector?
Ans: Often what you find when metal detecting are old scraps and things that aren’t worth much. However, if you find historical artifacts and things that may be of value, these usually need to be declared. The best things you can find when metal detecting are actually never going to remain in your possession.
