1\/ Spuriousness and Distorted Responses<\/u><\/p>\n

In some ways the CTX is highly accurate–other not.<\/p>\n

a\/ Target Size. <\/u><\/p>\n

The CTX\u2019s high Gain circuitry acts to make all targets sound bigger.\u00a0 This sometimes makes it hard to identify objects that are too small to be of value.\u00a0 The solution is to use the Pinpoint feature to see how responses stand out from the surrounding ground.<\/p>\n

Anything that\u2019s really faint should be suspect.\u00a0 Especially–where you have a loud discriminate response and a faint Pinpoint sound–suspect junk.<\/u><\/em><\/p>\n

As mentioned earlier, reducing the Volume Gain will give a more accurate reporting on these micro conductors.<\/p>\n

A second component to this sizing problem is that with the CTX\u2019s algorithmic discrimination\u00a0 targets may respond in a given category based upon their size.\u00a0 That is, a low gold \u201cnumber\u201d will also let in big foil because it mimics the size \/ conductivity <\/em>\u201cbracket\u201d that you are after.\u00a0 Even though the big foil target fits neither category you are trying to isolate–in combination,<\/em> it passes.<\/p>\n

b\/ Solidity<\/u><\/p>\n

This distortion is a result of the amplification that high gain circuitry and a processed signal create.\u00a0 Targets often sound \u201cfuller\u201d than they are.\u00a0 I\u2019ve had a lot of experience with this problem running pulses that transmit at 10 uSc and other VLF machines that run at high frequencies.\u00a0 These machines are made to bring up small stuff and there\u2019s a big learning curve in learning to tell what\u2019s what.\u00a0 With the CTX, even hairpins and tiny bits of aluminum can initially sound solid.\u00a0 (See \u201cCTX 3030 ID Tools\u201d<\/u><\/em> below).\u00a0\u00a0 It\u2019s tough area of learning with the CTX.\u00a0 The several gold target studies I\u2019ve looked at show gold (some of it small earrings and chains) coming in though the entire low range.\u00a0 At the same time, there are a lot of signals in that range that are just not quality responses.\u00a0\u00a0 Much of this obvious trash can be recognised if you take the time to examine them.<\/p>\n
