Discovering treasure with a metal detector is one of the most satisfying and exciting things you can do outdoors. And, it’s not just for beginners! Many different metal detectors are available, each with unique features.
Here’s a guide to help you choose whether a deep search metal detector or hand held metal detector is suitable for you, what features to look for, and how to get started using your new treasure-hunting tool.
How Do Metal Detectors Work?
The most important thing you should know about metal detectors is that they don’t work unless you’re actively searching for something. The first thing you should do when using your metal detector is to ensure that your ground rod is secure and grounded properly. Then, turn on your metal detector and let it run for at least 30 seconds.
When a metal detector is switched on, it emits a signal that a metal detector controller can detect. The controller then instructs the search coil to move in the direction of the signal while also instructing the transducer to send out an electromagnetic field.
The target response from this electromagnetic field indicates whether or not there are any conductors present in those areas. Nothing happens if there are no conductors; if there are conductors, high resistance will be detected, and the controller will send out an alarm sound.
Types of Metal Detectors
Metal detectors are small devices that can be handheld or mounted on a belt or backpack. Detectors use electromagnetic waves to detect metal objects on the ground. There are many different types of metal detectors on the market today, but they all have one thing in common: they detect metal. Below are some of the most prevalent metal detectors:
VLF (Very Low Frequency)
This metal detector can detect items as deep as 30 feet below the surface. VLFs are accurate but not very sensitive; therefore, they will only pick up small items such as coins, jewellery, and jewellery pins. It works by sending out a signal that penetrates the ground and then sends back information about any detected objects.
This metal detector uses two coils at different frequencies, one for sending and one for receiving signals. By alternating these frequencies, the machine can create a pulse that can be detected by other devices such as radio waves or sonar technology. These devices use an electric current to detect metal objects buried in the ground. Pulse induction detectors are more sensitive than VLF detectors and can be used in wet soil or on top of the water.
FBS – Function-Based Search
This single-frequency machine uses a series of electromagnetic coils to detect metal objects. The coil system works by emitting radio waves into the ground and watching for reflections in return. If a piece of metal is present, it will reflect the waves to the coil system at a higher intensity than the natural ground.
How to Choose a Good Metal Detector
Metal detectors come in many different shapes and sizes. The most common ones are handheld and deep search metal detectors with a built-in GPS.
The best way to choose a metal detector is by deciding what you want it for. If you want to find large objects such as guns and knives, go for a deep search metal detector. If you want to find coins, then go for a coin detector. If you want to find jewellery or other small items, then go for a handheld metal detector.
Metal Detecting Tips
Here are some more metal detecting tips to help you get the most out of your metal detector.
1. Always wear ear protection when using a metal detector. It makes sense. So many people forget that ear protection is not just for when you’re in the field but while working on your equipment.
2. Inspect all batteries before use, especially if you have been keeping them in storage or have left them without being charged for an extended period. It can lead to corrosion and damage-sensitive electronics and batteries in your detector.
3. Don’t use the same battery in multiple detectors. It is common practice for manufacturers to recycle old batteries into new ones, which means that there may be toxic chemicals inside that could harm you if you aren’t careful when using them again after being recycled.
4. Never store a battery inside a metal detector; this can cause damage to sensitive circuitry and components inside your unit if they heat up enough during operation. If you must store batteries inside your unit, make sure the batteries are not touching anything else. Both handheld and deep search metal detectors are entirely safe to use, except when it involves marine animals. Metal detectors do not mistakenly give you proof of long-lost treasures, but the detectors can tell you if there is a particular metal hidden within the clutter. Whether it’s about archaeology, jewellery, gold coins, old silverware, or anything else, this machine can assure you whether your assumption is valid. It has many benefits, including the fun of finding stuff that others don’t.
