VLF Technology (Continuous Sine Wave)

in Serious Detecting Blog

This is the traditional type of technology used in most basic metal detectors. These detectors are also known as VLF (very low frequency) models. While signal processing has improved enormously, the basic way that the signal is sent out and received back hasn't changed a lot. Continuous sine wave detectors create an electro-magnetic field, which is transmitted in to the ground in a continuous wave.
