45 KHZ VLF & 24-BIT SIGNAL PROCESSOR: This primary combination greatly boosts sensitivity to gold beyond that of other single frequency VLF detectors over a wide range of nugget sizes, without introducing excess noise and false signals..
IMPROVED DISCRIMINATION: The GOLD MONSTER 1000 also has improved ferrous/non-ferrous discrimination and copes better with conductive (salty) soils than higher frequency detectors, making it the perfect choice to maximise your gold recovery..
VERY LOW FREQUENCY: VLF (Very Low Frequency) is a conventional single frequency sine wave continuous transmission technology. This is the traditional type of technology used in most basic metal detectors. Single frequency sine wave detectors create an electro-magnetic field, which is transmitted into the ground in a continuous wave. The receive signal processing has improved enormously. .
