What are Search Coils and Are They Important for Metal Detection?

If you're new to metal detecting, you may have heard the term "search coil" but not fully understand what it is or why it's so important. 

The search coil is the circular part of the metal detector that is placed on the ground to search for metal objects. It emits an electromagnetic field that penetrates the ground and detects metal objects based on their conductivity. Simply put, the search coil is the heart of the metal detector and plays a crucial role in your success as a treasure hunter.

What are the best brands of search coils

When it comes to search coils, there are several top brands in the metal detecting industry. Here are some of the best brands to consider:

How to use search coils

Using a search coil is relatively straightforward, but there are a few tips to keep in mind to ensure the best results:

· Swing Slow and Steady. When swinging the metal detector, it's important to do so slowly and steadily. This will give the search coil time to emit an electromagnetic field and detect any metal objects in the ground.

· Keep the Coil Close to the Ground. The search coil should be kept as close to the ground as possible, as this will help to increase its sensitivity and detect smaller objects.

· Use the Right Coil for the Job. Different types of metal detecting require different types of search coils, so it's important to use the right coil for the job. For example, small coils are better for tight spaces, while larger coils are better for covering a lot of ground quickly.

When to Replace Search Coils

Over time, the search coil may start to wear out or become damaged, which can affect its performance. It's important to replace the search coil when this happens to ensure that you're still able to detect metal objects effectively. Here are some signs that it's time to replace the search coil:

· Decreased Sensitivity. If you notice that the metal detector is not picking up as many signals as it used to, it may be time to replace the search coil.

· Physical Damage. If the search coil is damaged, such as if it has cracks or holes, it's time to replace it.

· Reduced Depth. If you notice that the metal detector is not detecting objects as deep as it used to, it may be time to replace the search coil.

In conclusion, the search coil is a crucial component of the metal detector and plays a big role in your success as a treasure hunter. Make sure to choose a high-quality search coil from a reputable brand, use it correctly, and replace it when necessary to ensure the best results.
