Unearth hidden treasures with the best search coils for metal detecting
Introduction:
Metal detecting is a fascinating hobby that has been around for centuries. Whether you’re searching for coins, jewelry, or relics from the past, having the right equipment is essential to success. One of the most important pieces of equipment in metal detecting is the search coil.
Search coils are responsible for transmitting and receiving signals that help detect buried objects. They come in various shapes and sizes, each with unique features designed to improve detection capabilities. In this roundup post, we’ll take a closer look at some of the best search coils available on the market today.
1. DD Search Coils:
DD (Double-D) search coils feature two overlapping D-shaped loops that work together to provide better depth and target separation than other coil types. These coils are particularly useful in areas with high mineralization or trashy conditions where conventional round coils may struggle.
One popular DD coil is the Minelab 11″ Double-D Commander Coil. This waterproof coil provides excellent sensitivity and stability in highly mineralized soils while offering good coverage area for efficient searching.
2. Concentric Search Coils:
Concentric search coils consist of two circular loops – one larger than the other – positioned concentrically (one inside another). The smaller loop transmits electromagnetic energy into the ground, while the larger loop receives any returning signal from a target object.
These type of coils offer greater sensitivity to small targets near the surface but have limited depth penetration compared to DD coils due to their smaller size. One example of a reliable concentric coil is Garrett’s 5″x8″ PROformance Concentric Search Coil which can be used on many different models including AT Pro/Max machines among others.
3. Elliptical Search Coils:
Elliptical shaped search coils provide better maneuverability when working through tight spots such as brush or rocky terrain since they have less surface area hitting obstacles during swings making them more maneuverable overall without sacrificing coverage area needed to detect targets.
One example of a reliable elliptical coil is the NEL Tornado 12″x13″ Search Coil which is compatible with various metal detectors including Minelab, Garrett AT Pro/Max and Fisher. It features excellent stability, sensitivity, and depth capabilities that make it an ideal choice for searching in tough terrain.
4. Waterproof Search Coils:
Waterproof search coils are designed to be used in wet environments such as shallow water or beaches where submersion may occur. These coils are usually made of materials that resist rust and corrosion while still being sensitive enough to detect small objects buried underwater.
One popular waterproof coil is the Detech 15×12″ SEF Butterfly Search Coil which can operate up to two meters deep depending on soil conditions. It’s perfect for detecting coins, jewelry, or relics submerged in freshwater or saltwater environments.
5. Large Search Coils:
Large search coils offer greater coverage area but sacrifice sensitivity to smaller targets due to their size and shape which tends to focus energy deeper into the ground rather than close to the surface like smaller concentric coils would do so well at. They’re ideal for covering large areas quickly but may miss small objects if not carefully searched through with proper technique.
One example of a reliable large coil is the Coiltek 14″ Elite Mono Search Coil which provides exceptional depth penetration when searching mineralized soils thanks to its larger size compared against other models like DDs or Concentrics styles available today from other brands as well!
Conclusion:
With so many different types of search coils available on the market today, finding the right one can seem overwhelming. However, by understanding your specific needs and considering factors like terrain type, target size & depth requirements among others you will be able choose one that suits your unique preferences and requirements best!
