Uncovering Hidden Treasures: The Benefits of Round Search Coils in Metal Detecting
Round Search Coils: A Closer Look
Metal detecting is a thrilling activity that has been around for centuries. It has become increasingly popular over the years, and modern technology has made it easier to locate hidden treasures. One of the essential components of metal detecting is the search coil, which is responsible for sensing metal objects buried in the ground. There are different types of search coils available on the market, but round search coils have gained popularity among hobbyists and professionals alike.
In this post, we will take a closer look at round search coils and why they are a valuable tool for metal detecting.
What Are Round Search Coils?
A round search coil is a circular-shaped component that attaches to the lower end of your metal detector’s shaft. This component plays an essential role in locating metallic objects buried beneath the ground surface.
Round search coils come in various sizes ranging from 4 inches to 15 inches or more. The size you choose depends on what you want to detect and where you plan to hunt. Smaller-sized coils are ideal for searching small areas like playgrounds or parks with lots of trash while larger-sized ones work best when covering large open fields or beaches.
The Benefits Of Using Round Search Coils
1) Increased Sensitivity
One significant advantage of using a round search coil is increased sensitivity compared to other shapes like elliptical or DD (double-D). With its circular shape, it can pick up signals coming from all directions around it, making it easier to detect small targets even at greater depths.
2) Better Ground Coverage
Another benefit of using a round coil is better ground coverage. Since these coils can detect metallic objects from every direction around them, they allow for more thorough sweeps across any terrain without missing out on anything important.
3) Easier Target Identification
When hunting in heavily mineralized soil conditions such as saltwater beaches or highly mineralized locations like old ghost towns where there may be many false signals, a round search coil can be beneficial. The circular shape of the coil makes it easier to distinguish between metal targets and mineralization or trash.
4) Versatility
Round search coils are versatile and can be used in different locations and applications. They work well on all types of soil, including highly mineralized grounds like saltwater beaches or old ghost towns.
5) Depth Performance
Round search coils have a better depth performance compared to other shapes like elliptical coils. This is because they can detect small targets at greater depths due to their increased sensitivity. However, this also means that larger rounds may not perform as well in shallow conditions where smaller-sized ones will come in handy.
How Do Round Search Coils Work?
Search coils work based on the principle of electromagnetic induction. When an electrical current passes through a wire loop (the search coil), it produces an electromagnetic field around it that interacts with any metallic object within its range.
When you move your metal detector over the ground surface, the search coil emits an electromagnetic field from its underside into the ground below it. If there is any metallic object present under the ground surface, its presence will disrupt this magnetic field causing a signal to be sent back up through the coil’s wire which then gets amplified by your detector’s circuitry.
The metal detector then interprets this signal and alerts you either audibly or visually depending on what model you have chosen.
Tips For Using Round Search Coils
1) Use The Right Size Coil
Using the right size round search coil is essential for optimal performance when hunting for specific targets in certain environments. Smaller-sized coils are great for searching small areas while larger-sized ones are ideal for covering large open fields or beaches.
2) Adjust Your Settings Accordingly
Adjusting your settings according to your environment is vital when using round search coils as they can pick up more signals than other shapes due to their increased sensitivity levels. It’s essential to adjust your discrimination levels to filter out unwanted targets and avoid missing anything valuable.
3) Sweep Slowly
When using round search coils, it’s crucial to sweep slowly and evenly over the ground surface. This will allow you to pick up signals from all directions around the coil, increasing your chances of finding something valuable.
4) Stay Close To The Ground
Staying close to the ground while sweeping will help increase sensitivity levels by minimizing any interference that may occur due to air gaps between the coil and ground surface.
Conclusion
Round search coils are an excellent tool for metal detecting enthusiasts who want increased sensitivity, better coverage, easier target identification, versatility in location and application as well as improved depth performance. However, before purchasing a round search coil, ensure that you choose one that is right for your level of experience and hunting environment. By following our tips on how best to use them correctly when out in the field metal detecting can be even more rewarding than ever before!
