Types of Metal Detectors

Pulse Induction Metal Detectors

Pulse Induction (PI) metal detectors are known for their ability to detect metal objects at great depths. They use a single coil to both transmit and receive signals. When the coil emits a pulse, it creates a magnetic field underground. If there is a metal object present, it will disrupt the magnetic field, causing a signal to be sent back to the detector. This type of metal detector is great for finding deeply buried treasures, but it may struggle with discriminating between different types of metals.

Very Low Frequency Metal Detectors

Very Low Frequency (VLF) metal detectors are the most common type used by hobbyists and professionals alike. They work by transmitting a continuous sine wave into the ground through one coil, while the other coil receives the reflected signal. VLF detectors are sensitive to different types of metals, allowing for discrimination between valuable items and trash. They are also capable of detecting small objects at shallow depths, making them ideal for general-purpose metal detecting.

Beat-Frequency Oscillation Metal Detectors

Beat-Frequency Oscillation (BFO) metal detectors are the simplest and most affordable option. They operate by generating two oscillating frequencies: one fixed and one variable. When these frequencies overlap or “beat” together, it creates an audible tone. BFO detectors are great for beginners due to their ease of use, but they lack the depth and sensitivity of PI and VLF detectors. They are commonly used for finding larger metal objects near the surface.

Choosing the Right Metal Detector

When choosing a metal detector, it’s important to consider your specific needs and preferences. Here are some factors to keep in mind:

Consider the Type of Metal You Want to Detect

Different metal detectors excel in detecting different types of metals. If you’re primarily searching for gold or other precious metals, a detector specifically designed for gold prospecting would be a wise choice. For general-purpose metal detecting, a versatile VLF detector with discrimination capabilities would be suitable for most situations.

Think about the Depth and Sensitivity Requirements

If you’re planning to search in areas known for deep targets, such as beaches or archaeological sites, a PI detector would be more suitable. On the other hand, if you’re mainly interested in shallow targets like coins and jewelry, a VLF detector with adjustable sensitivity would be a better option.

Consider User-Friendliness and Portability

Metal detecting should be an enjoyable and comfortable experience. Look for detectors with intuitive controls and an ergonomic design that won’t strain your arm during long sessions. Consider the weight and adjustability of the detector, especially if you plan to cover large areas or face challenging terrains.

Understanding Different Search Modes

Metal detectors offer different search modes that can enhance your detecting experience. Understanding how each mode works will help you make the most of your detector’s capabilities. Here are the three common search modes:

All Metal Mode

In All Metal Mode, the detector responds to all types of metals without discriminating between them. This mode is useful when you want to detect all objects in an area, regardless of their composition. It’s particularly handy for finding deeply buried or valuable items that might be missed in discrimination mode.

Discrimination Mode

Discrimination Mode allows you to selectively filter out unwanted metal targets based on their conductivity. This mode helps you avoid digging up trash or undesirable objects by setting the detector to ignore signals from certain metals, like aluminum foil or iron. Discrimination capabilities vary between detectors, so it’s important to understand the limitations of your specific model.

Pinpoint Mode

Pinpoint Mode is used when you’ve located a target and want to precisely determine its location. By pressing a button or switching to a designated mode, the detector narrows down the search field and provides a more accurate indication of the target’s position. This mode is especially useful for avoiding unnecessary digging and recovering targets more efficiently.

Preparing for the Search

Before embarking on your metal detecting adventure, some crucial preparations need to be made. Here are some steps to ensure a successful and enjoyable search:

Research the Area

Take the time to research the area you plan to search. Look for historical records, old maps, or personal accounts that can give you insights into potential hotspots for lost items. Local libraries, historical societies, or online forums dedicated to metal detecting can be valuable sources of information.

Check Local Regulations and Obtain Permissions

Depending on your location, there may be regulations in place regarding metal detecting. Some areas, such as national parks or private properties, may require permission before conducting any searches. Ensure that you comply with all applicable rules and obtain any necessary permits to avoid legal issues.

Assemble the Necessary Equipment

Before heading out, make sure you have all the essential equipment. This includes your metal detector, batteries, headphones to hear faint signals, a digging tool like a trowel or shovel, a pouch or bag for recovered items, and a pinpointer device to assist with precise locating. Dress appropriately for the weather and consider wearing comfortable shoes for long walks and challenging terrains.

Techniques for Effective Searching

To make the most of your metal detecting experience, it’s important to employ effective search techniques. Here are some tips to help you cover more ground and increase your chances of finding valuable items:

Cover the Area Methodically

Start by dividing the search area into smaller sections or grids. This will help you systematically search the entire area without missing any spots. Move slowly and swing the detector overlapping each sweep to ensure thorough coverage. Keep in mind that it’s better to search a smaller area thoroughly than cover a larger area hastily.

Sweep the Coil in Overlapping Patterns

The way you swing the detector’s coil can significantly impact your search efficiency. Hold the coil parallel to the ground and swing it in a smooth pendulum motion. While moving forward, make sure each sweep overlaps the previous one by a few inches. This ensures that you don’t miss any potential targets.

Take Advantage of Pinpoint Mode

When your metal detector detects a target, switch to Pinpoint Mode to locate and recover the item precisely. Move the coil in a figure-eight pattern over the target, listening for the strongest signal and noting its location. Use a pinpointer device to narrow down the spot, and carefully dig the target to avoid damage.

Identifying Potential Target Signals

To distinguish between valuable items and common debris, it’s important to understand the signals your metal detector provides. Here are some factors to consider when identifying potential targets:

Differentiating Between Ferrous and Non-Ferrous Metals

Metal detectors can differentiate between ferrous metals, such as iron or steel, and non-ferrous metals like gold, silver, or copper. Ferrous metals typically produce a lower tone or a negative signal, while non-ferrous metals produce a higher tone or a positive signal. This discrimination function helps you prioritize the targets you decide to dig.

Understanding Signal Strength and Tone

The strength of a metal detector’s signal can give you an indication of the target’s depth or size. Small or shallow targets tend to produce weaker signals, while larger or deeper targets produce stronger signals. Additionally, each type of metal may emit a distinct tone, allowing experienced detectorists to identify certain metals by sound alone.

Recognizing Common Target Signals

Different metal objects can produce different signals, even within the same category of metals. By familiarizing yourself with common target signals, you can learn to distinguish between trash and potentially valuable items. Experienced detectorists often spend time practicing with known objects to develop their recognition skills.

Tips for Digging and Recovering Lost Items

Once you’ve located a target and confirmed it’s worth digging, it’s important to use appropriate techniques to recover your find without causing unnecessary damage. Here are some tips to help you dig and handle recovered items responsibly:
