Diff. between 2 filter, 3 filter, or 4 filter machines??
- Thread starter Canewrap

It's the # of computer filters that the signal has to pass through, as it is processed to eventually become a "beep". The outcome is that 2 filter machines have less depth usually, but are better in iron (for target separation and target averaging). 4 filter machines are deeper seekers, typically (but not always) have a longer drawn out beep, but are not as good at target averaging and separation. An example of a 2 filter would be the Tesoro Sabre or Whites classic, and an example of a 4 filter would be a 6000 di pro, XLT, etc....
Here's a little something that George Payne, who designed the first detectors with ground balance, discrimination and almost every other feature found on detectors-- including the use of filters--said about them.
"There are two channels of information processed in the motion mode of a metal detector. Those two channels are typically referred to as the R and X channels. X is generally referred to as the discrimination channel and contains information about the ground as well as info about a target. Both channels go through filters, not only to remove extraneous noise but also to keep the two signals in sinc. Some detectors have two filters, some three, some four and a few have variable filters. If other factors are relatively equal, four filter detectors typically have better depth in soil conditions with higher mineralization levels, in ground with mild to moderate mineralization two filter detectors go deeper."
