How The Metal Detector For Gold

Metal detector is very important for use in a process of finding land that have potential metallic mineral content. Because the metal detector will be able to respond to the presence of a metal or any type conductive or magnetic materials in rocks in the soil.

How does this metal detector can work to identify the various metals is by testing the conductivity of the metal. A target signal is eliminated for unwanted metal such as the remains of iron & steel, pull tabs, bottle tabs and others in the same group, while increasing target signals high conductive metal such as gold along with brass and silver.

Metal detector is also very useful in the search for gold ore, so by using our metal detector equipment with easy to find a gold metal content.Various types of metal detectors at this time has been widely developed by various manufacturers and some manufacturers of metal detector maker also has characterized the search uses a mineral or metal targets.A metal detector is not much of a complex devices. It has three basic parts.

The first is a coil that can come in many forms, a power supply and a control box. The work lies largely in the control box because it is a part of that beats when there is metal around and ticking this is what's causing the metal detector to do its job.In the use of a detection of gold, a soil condition is affecting the operation of metal detectors is where the heavy minerals and heavy soil conditions will cause the electromagnetic field and result in shrinking the primary weakness of a signal on the metal at depth. And a soil in wet conditions allow greater penetration of the main magnetic field, providing better signal coverage on the basis of soil depth. 

These few simple steps that can be used when we will start using a metal detector:
  1. Check the battery condition. Batteries should always be in good shape, so that when in use the metal detector can work well 
  2. Headphones should always be used when starting to use in search of minerals or metals, due to the use of headphones signal will be easier to listen. Some prospectors are also often add a device mounted audio amplifier to amplify small signals, so that small signals can be easily detected and more sensitive in receiving a signal.
  3. Discrimination should always be zero.
  4. Adjusting the audio so that the first tuning of the detector hum barely audible.
  5. Prior to the area of land that will be the detection phase and that we should be easy to distinguish the resulting sound detection devices, detection devices should be the gold we test first, you try to use metallic gold you have and bury in the soil at the depth of 30 cm and you listen noise and signal whether it is correct. And then you try to bury it back a small iron equal depth and listen to sounds and signals. The function of this method is to differentiate and to familiarize us with the sound generated from the detection devices. The resulting audio signal usually varies according to the type of target. Gold tends to produce short signals, signal a sharp metal object while generating broad signal.  
How to detect a metallic gold on a field:
  1. After determining the location for hunting then do not use a random way or detect arbitrarily. Decide in advance how much the location for the detection (eg from some vertex) and then begin to detect any part of the site. 
  2. Enabling and allow to stand for 10-15 minutes to stabilize the battery.
  3. Places to V.L.F. mode. The VLF, or land mode, must always be used for prospecting. 
  4. To begin with, the sensitivity of the signal should be placed at the half. This can be increased or decreased according to soil conditions. If placed at a minimum, a small nugget to be missed, therefore, always place it on the maximum allowable setting.
  5. Do it while maintaining the coil 1 cm from the ground and swinging slowly. Swing the coil is over a meter from side to side. After that move forward a distance of no more than swinging the coil. If we find a gold there is usually more than 1, so do it slowly.
  6. If the tools we have already had a ground balance feature, then turn ground balance every few minutes (depending on the condition of mineral soil). And to compensate for soil conditions, raise and lower the search coil (from low to high 60cm 15cm). As the search coil is lowered, the audio signal will either increase or decrease in strength.
  7. Ignore it changes the sound so wide. It must be remembered every inflection to signal a short and sharp, should be explored because it could have been scrap metal or gold. 
  8. If you already specify the location to be dug nearby trash clean up first so that the tool could be deeper penetration into the soil and the received signal is stronger. Gently clean as we could have rid the land that is gold. For more certain land to be disposed of in the hold to the detector.  
  9. For large areas that do not ever detect the spot to spot (one point to another point) quickly. But detecting a spot slowly, because sometimes it takes more than a new detection times we will find gold at that point.
