Rob Filter question

[Elton]

How will I know what filter setting to go to ............ what is the key to knowing when it is set right ??

Adjusting the filters and recovery delay will influence how the detector identifies a Target. Set a coin to a depth where the target signal is just being detected. Then try the different filters to see which filter gives the best response. Unless the target is at its limit all the filters will probably give a good response.

Now most programs use the 5Hz Band pass filter as the default. This is the best overall choice for low-to-moderate mineralization, has good EMI rejection, and allows for a slower sweep speed while still working well with faster sweep speeds.

Modern VLF detectors use filters to separate the target responses from the ground response. Filters are also used to minimize EMI noise. The best filter to use depends on the strength of ground mineralization plus other factors. Modern VLF metal detectors use electronic filters both to remove unwanted noise

You had sent me a communication that you guys and Whites has learned a little more about filtering since V3i came out.. So I wanted to be sure I had it right on going lower first and maybe only filter setting.
