Frequency
EQUINOX Series detectors have simultaneous
multi-frequency capability with a technology called
Multi-IQ, as well as a selection of single frequencies�
Frequency adjustment is local; only the current Search
Mode Profile is affected by changes to this setting�
For all Search Modes, Multi is the recommended
Frequency setting�
Perform a Noise Cancel (page 25) each time the
Frequency is changed�
CHANGING THE FREQUENCY
1. Press the Frequency button to scroll through the
available frequencies�
The Frequency button
The Frequency is shown on the Frequency Display�
Displays a rectangle when operating in
Multi-IQ (simultaneous Multi-frequency)�
Displays the current selected single
frequency in kHz: 4, 5, 10, 15, 20*, or 40*�
2. Perform a Noise Cancel (page 25)�
MULTI-IQ OPERATION
Multi-IQ operates across the full spectrum of frequencies
simultaneously, allowing it to cover a much broader range
of targets than any one single frequency can�
Detecting using Multi-IQ is recommended wherever
possible, as it will give you the best chance of detecting a
broad range of targets whilst also giving a more stable and
accurate target ID than single frequencies� See "Target ID
Accuracy" on page 41 for more information�
SINGLE FREQUENCY OPERATION
Using a single frequency may have a slight advantage over
multi-frequency in certain detecting situations�
For example; if you were searching only for larger high
conductive targets located at great depth, using 4 or 5 kHz
may give an advantage� Similarly, if you were hunting only
for very fine gold jewellery at a shallow depth, then 20 kHz*
or 40 kHz* (using Park, Field or Gold* modes only) may give
better results in some detecting environments, such as at
a beach on the dry sand�
In some noisy environments (e�g� high Electromagnetic
Interference, where Noise Cancel is not fully effective),
a single frequency may pick up less noise than Multi will,
however maximum target sensitivity over a wide range of
targets will be reduced�
FREQUENCIES AND SEARCH MODES
Not all frequencies are available in every Search Mode�
Each Search Mode is limited to the frequencies that
provide the best performance for that mode� For example,
Park and Field Modes can operate across every available
frequency setting, as good results can be achieved in any
frequency�
Beach Mode however, can only perform successfully
in typical beach conditions in Multi, therefore single
frequencies are not available�
Similarly, Gold* Mode is optimised for detecting low
conductive gold nuggets that are more easily detected at
higher frequencies� Therefore the lower single frequencies
(4, 5, 10, and 15 kHz) are not available�
