Filters

As presented in Chapter 1, modern VLF detectors use filters

to separate the target responses from the ground response. Fil-

ters are also used to minimize EMI noise. The best filter to use

depends on the strength of ground mineralization plus other fac-

tors. VX

offers two filters to choose from: a 5Hz filter for low-

to-modest mineralization and 12.5Hz for more severe ground

conditions. Filters and response speeds are explained in detail in

Chapter 6.
