What to Look For in a Metal Detector Machine
Whether you’re a veteran treasure hunter or just want to find that lost ring under the surf on your next beach day, a metal detector machine can help. The right one for you will depend on your budget, skill level, and intended use. But, before you rush out and buy the latest top-of-the-line model, there are a few things you should keep in mind.
The first thing to consider is the price of a metal detector machine. A basic detector will start at less than $100, but you’ll need to spend a bit more for a higher-end option with more advanced features.
A metal detector is an electrical device that uses a magnetic field to locate objects in the ground. The detector’s circuitry produces alternating currents, and these pass through a coil to produce a magneto-electromagnetic field. When an object, such as a piece of metal or a mineral, passes through the coil, its magnetic fields interact with the alternating currents and create eddy currents. The resulting change in the alternating currents creates a signal that can be detected by another coil on the detector, which then provides information about the type and location of the metal object.
As the electronics of metal detector machines improved, they became more effective at locating a wide range of different objects. This was mainly due to the discovery that different metals had different phase responses to alternating currents. This allowed the detector to distinguish between different types of metal and to avoid unwanted signals, such as those from ferromagnetic alloys.
Another improvement was the development of pulse induction sensors, which are found on more sophisticated models. These sensors have two coils, with one acting as an RF transmitter and the other as a receiver. The alternating currents that pass through the coils generate a magnetic field, and when an object of a certain type of metal is close enough to the sensor, it triggers eddy currents in the coil. The time it takes for these eddy currents to decay is measured by the circuitry, and this signal is translated into audio that is audible by the user.
The display of a metal detector can include several useful elements, including a sensitivity meter, discrimination meter, notch adjuster, and metal adjuster. The display also shows the sensitivity settings for the detector, and you can choose between a number of detection modes including coin hunting, jewelry, relic hunting, and custom settings that allow you to save a frequency setting for your particular needs.
If you’re new to metal detecting, we recommend starting with a VLF detector. This technology is found in most detectors that are under $1,000, and it’s great for coins, jewelry, and relic hunting. If you’re planning to hunt in heavily mineralized soil, however, you’ll need a more expensive pulse induction machine that can punch through salt and iron. These devices can also be more difficult to operate for beginners, so consider upgrading to a more advanced model when you’re ready for a challenge.
