Vflex Technology - Minelab X-Terra 50 Manual

The X-Terra detectors are Minelab's first products
to incorporate VFLEX Technology.
VFLEX uses state of the art digital and mixed-signal
components to enhance standard single frequency
technology by replacing most of the analogue
circuitry with digital signal processing. The small
amount of analogue circuitry still employed has
been very carefully designed and calibrated to
obtain the outstanding sensitivity, stability and
repeatability required to match the performance
of the processing in the digital domain.
This radical departure from traditional approaches
to metal detector design has been made possible
by advances in electronics that power personal
digital assistants, cell (mobile) phones and
high-fidelity portable audio.
