Metal detecting is an exciting hobby that can lead to some incredible discoveries. However, to get the best results, you need to use the right metal detecting frequency. Different frequencies have different effects on how a detector responds to metal targets, and choosing the right one can make all the difference. In this blog post, we'll explore the pros and cons of different metal detecting frequencies to help you make an informed decision.
Low frequencies are typically in the range of 3-7 kHz. They are ideal for detecting larger, more conductive targets at greater depths. This frequency is best for finding silver, copper, and brass objects. Low frequencies are also great for detecting targets in heavily mineralized soils, making them an excellent choice for relic hunting. However, low frequencies are not as effective at detecting small targets. They also tend to be less sensitive to low-conductive targets, such as gold.
Medium frequencies are typically in the range of 7-15 kHz. They strike a balance between low and high frequencies, making them a versatile choice for general metal detecting. They are effective at detecting a wide range of targets, from coins to relics, and work well in a variety of soil conditions. Medium frequencies are also good at detecting small and low-conductive targets, such as gold nuggets. However, the depth capabilities of medium frequencies are not as great as low frequencies, and they may struggle in heavily mineralized soils.
High frequencies are typically in the range of 15-30 kHz. They are ideal for detecting small, low-conductive targets, such as gold nuggets, small jewelry items, and hammered coins. High frequencies are also very sensitive and can detect targets close to the surface. However, high frequencies are not as effective at detecting larger targets at greater depths. They are also less effective in mineralized soils, which can cause false signals and reduce detection depth.
In conclusion, choosing the right metal detecting frequency is crucial to getting the best results. Each frequency has its unique strengths and weaknesses, and understanding these can help you make an informed decision. Low frequencies are ideal for detecting larger, more conductive targets at greater depths, while high frequencies are best for detecting small, low-conductive targets close to the surface. Medium frequencies strike a balance between the two and are ideal for general metal detecting. Ultimately, the best frequency for you depends on your specific needs and the conditions you'll be detecting in. Happy hunting!
