Frequency
MANTICORE features a high-power 
simultaneous multi-frequency technology 
called Multi-IQ+, and also has a selection of 
single frequencies.
Frequency adjustment is local; only the current Search 
Mode is affected by changes to this setting.
Multi-IQ+ is the default and recommended Frequency 
setting for all Search Modes.
Perform a Noise Cancel (page 57) each time the 
Frequency is changed.
Frequency in the Settings Menu. Frequency on the Detect Screen.
CHANGE THE FREQUENCY
1.  Navigate to:   Settings >   Frequency
2.  Press / to select a Frequency. The new Frequency 
setting will be displayed on the Detect Screen.
3.  Perform a Noise Cancel (page 57).
FREQUENCIES AND SEARCH MODES
Each Search Mode is limited to the frequencies that 
provide the best performance for that mode.
All-Terrain modes can operate successfully across every 
available frequency setting, therefore single frequencies 
are available in All-Terrain.
Beach modes can only perform successfully in typical 
beach conditions in Multi-IQ+, therefore the single 
frequencies are not available.
Similarly, Goldfield is optimised for detecting low 
conductive gold nuggets that are more easily detected at 
higher frequencies. Therefore the lower single frequencies 
(5, 10 and 15 kHz) are not available in this mode.
MANTICORE does not have a 4 kHz single frequency 
setting. Instead, the All Terrain High Conductors Search 
Mode provides a Multi-IQ+ based mode that can achieve an 
operating frequency even lower than 4 kHz. This provides 
the benefits of a low frequency/high power mode for 
detection and discrimination of high conductors, while 
retaining the substantial benefits of Multi-IQ+.

MULTI-IQ+ OPERATION
Multi-IQ+ operates across the full spectrum of frequencies 
simultaneously, allowing it to cover a much broader range 
of targets than a single frequency can.
Multi-IQ+ delivers superior performance over single 
frequency operation in almost all conditions.
Detecting using Multi-IQ+ at all times is  
recommended because:
  It gives the best chance of detecting a broad  
range of targets.
  Multi-IQ+ Target IDs are more stable and accurate 
than single frequencies. See "Accuracy Factors" on 
page 25 for more information.
