Multi-frequency-Full
Band Spectrum (FBS) Technology
When developing the Quattro MP, Minelab's scientists looked at
developing a truly easy to use yet extremely powerful multi-purpose metal
detector. Discussions with seasoned treasure hunters from around the world
identified a number of possible enhancements for operators. Features of the
Quattro MP detector include:
Remarkable detection depth
- Accurate identification of targets to greater depth
- Enhanced detection of desired targets amidst iron
"trash"
- Enhanced detection capabilities when searching
salt-water beaches
Most detectors on the market operate on a single (or dual)
frequency, ranging from 1 to 70 kilohertz (kHz). Although this technology
has served the industry well for years, Minelab's scientists found that a
frequency that worked well in one area would often offer only marginal
performance when used in another location. Ground mineralization, trash
content, and target size all had an effect on how effective a detector
transmitting a single frequency would operate.
Full Band Spectrum technology combines Minelab's existing
multiple frequency BBS technology with a
powerful new microprocessor to give:
Greater Detecting Depth
- Consistent sensitivity over a wide range of targets
- Less interference from electromagnetic sources
- More accurate identification of target characteristics
The Full Band Spectrum (FBS) circuit automatically
transmits multiple frequencies simultaneously. This increased frequency
range means that the signal received from the detector coil is analyzed from
a wide range of responses. This information is relayed to the operator via
the speaker or headphones and the control panel's liquid crystal display as
an audio or visual target response.
Put simply, Minelab's unique FBS technology means
deep, sensitive, accurate detecting.
Ground Compensation
The Quattro MP uses a sophisticated approach to the elimination of
signals caused by ground mineralization. Unlike other forms of ground
balance that require
constant readjustment, FBS technology uses advanced digital filtering to
eliminate the influence of ground signals.
Operating Frequencies
A metal detector's electromagnetic operating frequencies are measured in
kilohertz (kHz). Low signal frequencies (e.g. 1.5 kHz) penetrate deepest,
but sensitivity to smaller targets is low. On the other hand, higher
frequencies have a more shallow depth of penetration but high sensitivity to
small targets. The Quattro MP's multiple-frequency operation provides the
advantage of both.
