Coils for Different Target Types: A Comprehensive Guide for Metal Detector Enthusiasts
Metal detecting is an exciting hobby that allows enthusiasts to uncover hidden treasures buried beneath the ground. However, one crucial aspect of successful metal detecting lies in choosing the right coil for your detector. Coils play a significant role in determining the type of targets you can locate and how effectively you can unearth them. In this comprehensive guide, we will explore different types of coils designed specifically for coins, relics, and jewelry hunting.
Coin Hunting Coils:
When it comes to coin hunting, accuracy and depth are key factors to consider when selecting a coil. Here are two popular options tailored for coin enthusiasts:
1. Concentric Coils:
Concentric coils are widely used by coin hunters due to their excellent target separation capabilities. These coils consist of two wire loops—one transmitting electrical signals and the other receiving them—positioned concentrically around each other. This design allows for precise identification and discrimination between targets close together.
Concentric coils excel at isolating individual coins within trash-ridden areas such as parks or beaches where multiple metallic objects may be present. They also offer good depth penetration but tend to have a narrower detection width compared to other coil designs.
2. Double-D (DD) Coils:
Double-D coils have become increasingly popular among coin hunters due to their superior ground coverage abilities while maintaining reasonable target separation capabilities. DD coils feature two D-shaped wire loops positioned side by side.
These coils provide better stability on mineralized soil conditions compared to concentric ones while still providing acceptable depth penetration levels required for locating coins at various depths.
Relic Hunting Coils:
For relic hunters searching historical sites or battlefields, choosing the right coil is essential as relics can vary significantly in shape, size, and composition. Here are two types of coils commonly used by relic enthusiasts:
1. Wide Scan/Spider Coils:
Wide scan or spider coils are specifically designed for covering large areas quickly, making them ideal for relic hunting. These coils feature a wide and elongated shape, enabling greater ground coverage while maintaining reasonably good depth penetration.
Wide scan coils excel at detecting larger relics buried deeply in the ground, such as cannonballs or musket balls. However, their target separation capabilities may not be as precise as those of concentric or DD coils.
2. Elliptical Coils:
Elliptical coils offer relic hunters a compromise between ground coverage and target separation. As the name suggests, these coils have an elliptical shape instead of the typical circular design.
The advantage of using elliptical coils lies in their ability to effectively discriminate targets within highly mineralized soil conditions while still providing reasonable depth penetration levels required for relic hunting. These coils are particularly useful when searching narrow spaces or areas with dense vegetation where maneuverability is essential.
Jewelry Hunting Coils:
When it comes to jewelry hunting, sensitivity and discrimination play crucial roles in successfully locating valuable items such as rings, bracelets, or necklaces. Here are two types of coils recommended for jewelry enthusiasts:
1. Small Concentric Coils:
Small concentric coils offer heightened sensitivity to small metallic objects like gold or silver jewelry pieces due to their smaller detection area and higher operating frequency. These compact-sized search heads allow users to get into tight spaces that larger coil sizes might struggle with.
Additionally, small concentric coils provide excellent discrimination capabilities by filtering out unwanted signals from ferrous targets commonly found near beaches or parks where lost jewelry is often discovered.
2. VLF (Very Low Frequency) Detectors:
VLF detectors equipped with standard-size search heads can also be used effectively for jewelry hunting purposes due to their high sensitivity settings and advanced discrimination features.
These detectors can detect low-conductive metals like gold more efficiently than other coil types while still offering acceptable target separation capabilities in trashy environments where discarded bottle caps or aluminum foil may be present.
In conclusion, selecting the right coil for your metal detector is crucial to optimize your chances of finding specific targets such as coins, relics, or jewelry. By understanding the characteristics and strengths of different coil types designed for each target category, you can tailor your metal detecting experience to suit your interests and increase the likelihood of unearthing valuable finds. Happy hunting!
