With VFLEX the search coil contains a preamplier that boosts the
received signal before noise can be introduced through the cable. This
signicantly reduces false signals and increases the detector’s sensitivity,
even in noisy environments such as under power lines.
Another benet of VFLEX’s preamplier and microcontroller in the
search coil is that the standard heavy weight twin shielded cable isn’t
required. The VFLEX coil cable is a light weight ‘Category 5e’ cable. This is
a relatively new cable specication and because of its immunity to noise
is widely used for high speed computer networking.
This has two advantages; one, the detector is lighter and two, the much
ner wires aren’t detected when the cable is bumped. This signicantly
reduces false signals from bumping the search coil on the ground and
allows the detector to be very sensitive without ever detecting the cable.
VFLEX uses little power, so four AA batteries last over 20 hours, with the
same performance maintained from charged through to discharged.
VFLEX is a signicant advancement of single frequency metal detection
technology. VFLEX provides precision digital calibration with the coil,
adjustable transmit frequency and continuous ground monitoring,
resulting in high performance across a wide range of target types and
ground conditions. These technological advancements ensure that VFLEX
detects deeper with higher sensitivity than any other single frequency
metal detector.
