CODEC SIGNAL CONVERSION
The 2nd generation X-TERRA Series incorporate
Minelab’s proven 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 equipment.
