How to Choose the Best Metal Detector For Gold
Metal detectors operate by sending out electromagnetic waves that penetrate the soil and detect magnetic responses from various metals; gold is highly-conductive so its signals are readily detected by detectors.
But different metals have different magnetic responses, and discrimination features on most detectors allow users to zero in on specific metals such as gold while disregarding unwanted trash metals like copper and nickel. This helps save time from having to gold detector for sale dig through piles of junk only to discover that you have found nothing worth digging for!
Hobbyists looking for other treasures such as coins and jewelry should opt for detectors that have multiple applications; the Garrett AT Pro and Nokta Makro Gold Kruzer are two excellent metal detectors capable of doing both jobs very effectively.
Most detectors operate at specific frequencies, so to locate gold more effectively you'll need one that operates at that frequency. Very Low Frequency (VLF) detectors were traditionally the go-to choice as their highly conductive frequencies can detect metals even in mineralized soils.
However, recent advances have brought pulse induction (PI) detectors that may perform even better than VLF machines in certain conditions. Of these machines, Minelab GPZ 7000 stands out as being particularly advanced - going up to 40% deeper than any other detector on the market!
