INFINIUM LS  DISCRIMINATION OPERATION

 DUAL TONE OPERATION.

This type of discrimination works on the magnetic conductivity of the target detected. In the past, steel and iron has been looked at as having a low conductivity. This is true in regards to the standard VLF detectors but is the opposite of Pulse Induction detection. With Pulse Induction, steel and iron is generally high conductivity to this form of detection. This is what the dual tone discrimination works on.

 When you detect a target, you will either get a high tone first followed by a low tone, or a low tone followed by a high tone. If you receive a high tone fist, this is indicating a low conductivity material, such as gold. If you get a high tone first, always check the target and never walk away from it. When a low tone is obtained first, this is generally indicating a high conductive material, which is where steel and iron predominately falls into this category.

 If the signal is quite strong, raise the coil and check the signal tone does not change. Sometimes a target response is so strong, that it can give a false tone response. By overloading the circuit.

 There are occasions where steel and iron can give a misleading high tone response due to having a form of plating on it. This is where the Reverse Discrimination comes into effect.  Following is a description of how to use the Reverse Discrimination.

 REVERSE DISCRIMINATION.

When a target has been detected and you wish to further verify the target response with the reverse discrimination, turn the discrimination fully up to iron check.

 If the target strength still stays the same or only reduces very slightly, then this would be indicating that it is mostly likely steel. If the opposite occurs, and the target response completely disappears or can only just be detected, then this is indicating that it is most likely not steel and should be further investigated. This loss or reduction of signal is what you can expect with gold nuggets detected.

 If the signal of the target is very weak, then caution should taken when using the reverse discrimination, as there is a possibility of eliminating the target, even if it is steel.

  These forms of discrimination are new to prospecting detectors. It will probably take awhile to master it, but once you have, it will give you an advantage over other prospecting detectors. You will find the dual tone discrimination will work to the depth of the detected target.

 Remember, there is no system that is 100% full proof, especially in the high mineralized soils. There are occasions where a piece of steel may fall into the gold detection region and visa versa. The more you use the Infinium LS detector, the better you will understand it.

 Happy Hunting.
