Target ID Number (Continued)
ACCURACY FACTORS
Target IDs can vary by a couple of numbers depending on a
range of factors including metallic composition, orientation,
depth, swing rate and Frequency setting.
Frequency — Multi-IQ+ Benefit
Detecting the same target with different Frequency
settings may vary the Target's ID by one or two numbers.
Multi-IQ+ technology gives greater Target ID accuracy and
increased detecting performance, especially in heavily
mineralised ground. In benign ground, a single frequency
may perform adequately, however depth and Target ID
stability will be limited by ground noise.
Multi-IQ+ simultaneous multi-frequency will achieve
maximum depth with a very stable target signal. In
mineralised ground, single frequencies will not be able to
effectively separate the target signal from the ground
signal, giving decreased results. Multi-IQ+ will still
discriminate effectively at depth, losing a minimal amount
of Target ID accuracy.
Overlapping or Adjacent Targets
Targets that are adjacent or overlapping can influence one-another, resulting in misidentification. A common effect is
that a weaker target will be 'dragged' closer to the stronger target, causing a different Target ID than if the targets
were detected individually. Targets of a similar type and signal strength can move towards each-other, 'meeting halfway'.
Conversely, if one target is very dominant, then the weaker target may not be detected at all.
TYPICAL TARGET EXAMPLES
While both the Target ID number and ID Map give a good representation of a target’s ferrous and non-ferrous properties,
good and bad targets can fall anywhere within the overall range from 1 to 99. The table gives some common examples for
good and bad targets, showing the area where they are likely to appear.
