Minelab’s VFLEX Technology
72
VFLEX technology transforms the common analogue single frequency
metal detector into a fully digital machine including a small computer,
called a microcontroller, inside the control box and also inside the search
coil.
The microcontroller in the control box generates a perfect high quality
sine wave. The sine wave is produced in the same way that your digital
CD player produces high quality sound. This is important, because perfect
sine waves don’t have distortions that create harmonic side frequencies.
With the removal of harmonic side frequencies maximum power is
transferred to the coil and detection depth is greatly improved with
increased sensitivity, TID accuracy and immunity to noise.
Understanding your X-TERRA - Technology
Due to small variations in the windings, no two search coils will be exactly
identical. This means that a search coil tuned to 3 kHz might actually be
a 3.0438 kHz coil or a 2.9635 kHz coil. The dierence may not sound like
very much, however if your detector keeps transmitting at 3 kHz it can
mean the dierence between missing or nding a valuable target.
