Raw Gold Detector
Raw gold detectors are metal detectors designed specifically to find nuggets and larger pieces of raw gold in sandy, mineralized soil. These detectors have a high sensitivity and are capable of detecting gold in very shallow depths. The best raw gold detectors offer a wide variety of search modes, a target strength meter, and adjustable sensitivity. They are also waterproof and come with a comfortable headset for listening to the audio signals.
Most gold metal detectors work by emitting a magnetic field that reacts with the natural magnetism of minerals in the ground, known as mineralization. Mineralization is created when sand, silt and other elements in the earth interact with the magnetic field of underground metals. When a piece of gold or other mineralized metal comes into contact with the magnetic field it causes a change in the time constant of the metal’s response to the magnetic field. This time constant change is detectable by the detector and indicates that there may be a metal target nearby.
The time constant of a target is affected by the size, shape and depth of the target as well as its composition and the ground conditions. Different types of metals have varying time constants. This information can be used to filter out non-gold targets from the signal produced by gold in a detector. A gold detector can also be re-calibrated on-the-fly to search for a broader or narrower range of time constants.
When choosing a raw gold detector it is important to remember that your results will vary depending on the ground conditions and افضل جهاز كشف الذهب the type of metal you are searching for. You should always consult the manufacturer’s user manual to ensure that you are using the right settings for the conditions and type of metal you are attempting to find. It is also a good idea to practice in your home garden to familiarize yourself with the sounds of a metal detector before heading out into the field.
If you are looking for a versatile raw gold detector, the Minelab Equinox 800 is an excellent option. This multi-frequency machine is capable of multiple simultaneous frequencies ranging from 5 – 40 kHz allowing it to detect a variety of gold-like metals as well as ancient coins, spearheads and jewelry. Its ground balance feature allows the operator to tune out signals from the soil and concentrate on gold-like signals.
This is a basic model and it doesn’t have the most advanced features but that hasn’t stopped many people from finding lost rings, undiscovered gold nuggets and other treasures with this device. It is easy to use with a simple control array that includes a switch to cycle through modes and a dial for adjusting sensitivity. It is a great choice for beginners to get started in the hobby and it is affordable as well.
