A metal detector is an electronic device that detects the presence of metals nearby such as gold, silver, coins and even valuable relics. It is mainly used for archaeology, as a hobby, security screening in airports for instance and also used for industrial and engineering purposes.

The concept of how a metal detector works is by the magnetic field is produced when your device is above a metal object. Hence, electric current flows inside the metal object thus triggering your metal detector to detect a metal.
Apart from that, choosing the best metal detector depends on where you live and plan to use it, your budget, and the objects you are interested in finding. However, most detectors manufactured nowadays are multipurpose so you don’t have to purchase one for a specific purpose only.

For example, if you live close to lakes, rivers or ocean in which your metal detectors need to be submerged in water, you should get a metal detector with waterproof housing for the best performance. Also, you’ll need to get a detector with higher power if you are to search for objects buried deeply with more depth.

Factors in choosing the best metal detector:

1. The depth is measured in metres.
2. The operating frequency is measured in kHz.
3. The weight is measured in pounds (lbs).
4. The setup is rated from easy to hard.
5. The accuracy is rated from low to high.

Depth

The depth is vertical distance measured of how deep your metal lies buried. Most metal detectors measures up to 8 inches depending on its individual capability and the surroundings. For example, a larger sized metal object is easier to be detected compared to a tiny piece.

Higher powered metal detectors operating at higher frequencies are able to detect metals with shorter depth which will give you a more precise reading. Also, it depends on the type of the soil as heavily mineralized soil will tend to reduce the penetration power of your detector.

Operating Frequency

Operating frequency plays an important role in finding the metal detected by your detector. Operating frequency in a metal detector is the number of electronic waves sent into the ground to detect metal.

For example detectors with lower frequency is better for detecting high conductivity targets with larger size meanwhile detectors with higher frequency is suitable to detect low conductivity targets such as gold nuggets with smaller size. High frequency detectors are more accurate as they detect metals closer to the surface.

Weight

The weight of the metal detector is the total mass of it altogether. It should be light so it is easier to transport and handle especially when you are going to be using it for a long period of time. Some metal detectors on the other hand can be dismantled into smaller parts so you can further reduce the weight and ensure much easier transportation.

Setup

The setup of the metal detector varies between easy and hard depending on its settings. Metal detectors with advanced features such as notch features as well as numerous level target ID and ground balancing requires more than the general knowledge on the operation of the metal detector.

However, you can always refer to the user manual and tutorial videos for further clarification and extra guidance.

Accuracy

The accuracy of the metal detector is how well it can detect a metal buried and pinpoint the exact location of it. Not only that, the accuracy of a metal detector can be greatly improved by getting a metal detector that has a pinpointer feature as well as discrimination mode.

The discrimination mode will help you choose useful metals by differentiating the valuable treasures from trash. Also, phantom or false signals can be prevented with an accurate metal detector.
