Buying a Gold Detector
For some people, a Gold detector is a great way to pass the time, while others enjoy it for the money it can make. Whether you're searching for lost wedding rings or treasure in the sea, metal detecting can be a fun and rewarding hobby.
A metal detector uses a search coil to send out a magnetic field that penetrates the ground. When the field comes into contact with a conductive object, such as gold, it creates an electromagnetic current that changes the signal received by the detector. The change is interpreted by the detector as an audible sound and displayed on its screen.
Different detectors use various frequencies to scan the ground, and the frequency can affect how sensitive or how deep a detector can find targets. A higher frequency generally means a detector is less susceptible to ground interference and can detect smaller objects. However, it also can decrease a detector's depth capability.
Regardless of the frequency, it's important to choose a detector that's appropriate for the terrain where you plan to hunt. Some detectors work best in rocky or volcanic areas while others do well in black sand beaches. The type of soil in an area can also affect how a detector performs, so check out the product's specifications to determine its ability to detect a variety of targets.
While any metal detector can be used to find gold, many companies offer detectors designed specifically for the task. These units typically have a اسعار اجهزة التنقيب عن الذهب higher price tag than other detectors, but they are designed to hone in on the elusive metal. Some of these detectors utilize a system called discrimination to filter out junk targets from the gold-producing signals. Discrimination is based on conductivity, with lower-conductivity targets such as aluminum being eliminated first. Gold and other high-conductivity metals, like lead, are left in the mix at a later stage.
Most detectorists start out with a basic, inexpensive model such as the Bounty Hunter and upgrade to a more specialized unit. These advanced models can be quite expensive, but they feature a variety of controls to fine-tune the machine's performance. Some of these devices can even pinpoint small gold nuggets down to an inch or two.
Many beginner metal detectorists opt to purchase a multi-purpose machine that can be used for finding gold as well as coins and relics. These versatile detectors usually feature a ground balance control that can cancel out mineral effects on the soil.
