Multi-IQ Technology
Multi-IQ is simultaneous multi-frequency detection and can be considered
as combining the performance advantages of both FBS and VFLEX in a new
fusion of technologies.
Multi-IQ achieves a high level of Target ID accuracy at depth much better
than any single frequency detector can achieve, including switchable single
frequency detectors that claim to be multi-frequency. When Minelab use
the term 'multi-frequency' we mean 'simultaneous' – i.e. more than one
frequency is transmitted, received and processed concurrently. This enables maximum target sensitivity across all target types and sizes,
while minimising ground noise (especially in saltwater).
The diagram is intended to be a simplified representation of how different frequencies of operation are better suited to different target
types; i.e. low frequencies (e.g. 5 kHz) are more responsive to high conductors (e.g. large silver targets) and high frequencies (e.g. 40 kHz*)
are more responsive to low conductors (e.g. small gold nuggets).
Single Frequency Ranges
As well as operating with multi-frequency transmission, EQUINOX detectors
also have single frequency options where all of the transmitter power is
combined into one frequency for finding a specific type of target.
When selecting a detector with single frequency options, it is important to
consider not only the number of frequencies but also the frequency range.
A detector with more frequencies, but a smaller range will usually be less
versatile than a detector with fewer frequencies and a wider range.
It is also important to recognise that some frequency bands may have limited
value due to being widely used by communication agencies, making them
unavailable for consumer products, such as metal detectors.
EQUINOX 600 offers 3 single frequencies of 5 kHz, 10
kHz, 15 kHz in addition to Multi, giving a 3 times (×3)
range or ratio from 5 kHz to 15 kHz, hence the 3F×3
technology designation.
EQUINOX 800 offers 5 single frequencies of 5 kHz, 10
kHz, 15 kHz, 20 kHz, and 40 kHz in addition to Multi,
giving an expanded 8 times (×8) range or ratio from 5
kHz to 40 kHz.
* 20 kHz and 40 kHz are not available as single operating frequencies in EQUINOX 600. The Multi-IQ frequency range shown applies to both EQUINOX 600 and 800. This diagram is
representative only. Actual sensitivity levels will depend upon target types and sizes, ground conditions and detector settings.
