This is where a multi-frequency detector such as the
Spectra
V3
i
really shines.
V3
i
transmits at
2.5kHz, 7.5kHz, and 22.5kHz, making it simultaneously “hot” on silver, relics, and gold. Single frequency
detectors are unable to have peak performance over such a wide range of targets. This is an advantage
not only in detecting desirable targets, but also in discriminating out undesirable targets. So multi-fre-
quency detectors get excellent depth over a much wider range of targets, and do a better job of identifying
targets. But
Spectra
V3
i
can also beat single frequency detectors at their own game:
V3
i
has the ability to
run in single frequency mode using any of its three frequencies, and the transmit waveform is optimized to
put all the energy into that one frequency. So if you want to hunt for only deep silver or only gold jewelry,
V3
i
can be optimized for these tasks.
A
fi nal advantage of multi-frequency is the ability to simultaneously balance ferrous ground min-
eralization and conductive salt ground. Single frequency detectors cannot do this, and usually struggle in
wet salt sand unless the sensitivity is turned down signifi cantly.
Spectra
V3
i
is the fi rst production frequency domain metal detector to simultaneously use more
than 2 frequencies. It is also the fi rst multi-frequency detector to offer optimized single frequency modes.
And
V3
i
is the fi rst to display the target phase response independently for each frequency. White’s will
continue to be a leading innovator in metal detection technology, and instead of misleading claims, we’ll
tell you what we are really doing.
