A Comprehensive Guide to Metal Detectors

Metal detectors have become increasingly popular among treasure hunters, archaeologists, and hobbyists. These handy devices are used to locate metal objects buried underground, making them essential tools for anyone interested in uncovering hidden treasures or exploring historical sites. In this comprehensive guide, we will explore the different types of metal detectors, the features to consider when purchasing one, the best metal detectors for beginners, helpful tips for beginners, and the essential accessories to enhance your metal detecting experience.

Metal detectors work by emitting an electromagnetic field from the search coil. When the coil comes into contact with a metal object, it disrupts the field, sending a signal to the control box. The control box then alerts the user with an audible tone or a visual display, indicating the presence of a metal object. While metal detectors are most commonly associated with treasure hunting, they are also used in various industries such as construction, security, and archaeology.

There are several types of metal detectors available, each with its own set of advantages and applications. The three main types are Pulse Induction (PI) metal detectors, Very Low Frequency (VLF) metal detectors, and Beat Frequency Oscillation (BFO) metal detectors.

Pulse Induction (PI) metal detectors are known for their ability to ignore mineralization and work well in saltwater. They are excellent for deep searching and can detect metal objects at greater depths. However, they are not as effective at discriminating between different types of metals.

If you're new to treasure hunting, starting with the best metal detector for beginners can make all the difference.

Very Low Frequency (VLF) metal detectors are the most common type and are suitable for various metal detecting tasks. They offer excellent discrimination capabilities, allowing users to distinguish between different types of metals. VLF detectors are also sensitive to smaller objects and work well in mineralized soil. However, they may struggle in highly mineralized areas.

Types of Metal Detectors

Pulse Induction Metal Detectors: These detectors use short bursts of magnetic fields to detect metal objects. They are ideal for deep searching and work well in saltwater or highly mineralized soil. However, they may not provide accurate discrimination between different types of metals.

Very Low Frequency (VLF) Metal Detectors: These detectors emit a continuous wave frequency and are versatile for different metal detecting tasks. They offer excellent discrimination capabilities and are sensitive to smaller objects. However, they may struggle in highly mineralized areas.

Beat Frequency Oscillation (BFO) Metal Detectors: These detectors use two coils to create a fluctuating magnetic field. They are simple to use and are suitable for beginners. However, they have limited depth capabilities and may not provide accurate discrimination.

Features to Consider

Sensitivity: The sensitivity of a metal detector determines its ability to detect small or deeply buried metal objects. Higher sensitivity levels are ideal for experienced users who want to find smaller objects, while lower sensitivity levels are suitable for beginners.

Discrimination: Discrimination allows the detector to distinguish between different types of metals. It prevents users from wasting time digging up unwanted objects like nails or bottle caps. Metal detectors with adjustable discrimination settings provide more control over target identification.

Depth Indicator: A depth indicator is a useful feature that provides an estimation of the depth at which a detected object is buried. This helps users determine if it is worth digging for the target.

Ground Balance: Ground balance adjusts the detector's response to mineralization in the soil. It helps in reducing false signals caused by mineralized ground, making the detector more accurate and efficient.

Target ID: Target ID shows a numerical value or provides an audible tone to indicate the probable type of metal detected. It helps users determine whether the target is likely to be valuable or not.

Coil Size: The size of the search coil affects the metal detector's sensitivity and coverage area. Larger coils can detect deeper targets but may sacrifice some sensitivity to small objects. Smaller coils are more sensitive to small targets but may have a limited detection depth.

Tips for Beginners

Start with a beginner-friendly metal detector: Begin your metal detecting journey with a detector specifically designed for beginners. These detectors are usually user-friendly and come with helpful features and settings that simplify the learning process.

Read the user manual: Familiarize yourself with your metal detector by reading the user manual. Understanding the functions and settings will improve your detecting skills and allow you to make the most of your device.

Practice in different environments: To gain experience and improve your skills, practice detecting in various environments such as parks, beaches, and fields. Each location presents different challenges and opportunities.

Learn to interpret signals: The signals emitted by a metal detector provide valuable information about the nature and depth of the target. Spend time learning and interpreting these signals to increase your chances of finding desirable objects.

Join a metal detecting community: Joining a metal detecting community or forum allows you to connect with experienced detectorists who can provide valuable tips, advice, and even potential detecting locations.

Metal Detecting Accessories

Pinpointers: Pinpointers are handheld devices that help locate the exact location of a detected object. They eliminate the need for repetitive digging and make target recovery faster and more precise.

Digging Tools: A sturdy digging tool, such as a shovel or trowel, is essential for excavating targets. Look for durable tools that can handle various soil conditions and have comfortable handles for ease of use.

Headphones: Using headphones while detecting allows for better target identification by blocking out external noise and amplifying subtle signals. Look for headphones specifically designed for metal detecting, with adjustable volume and comfortable ear cups.

Coil Covers: Coil covers protect the search coil from scratches, abrasions, and general wear and tear. They help prolong the life of the coil and maintain optimal performance.

Carrying Bags: A carrying bag or backpack is essential for transporting your metal detector and accessories. Look for bags with padded compartments and adjustable straps for maximum comfort and convenience.
