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�
