I have a little time before getting to work so I thought I would tell you about some of the Filter settings. For the average user, you can use the factory preset and do just fine, but for the tinkerer you can set the filtering system to squeeze out a little more depth. In older terminology it would be considered an 8 filter detector, but in today's microprocessor controlled detectors, it is really one adjustable filter with 8 selections. Two types of filters are used with 4 speeds available for each type of filter, 5 Hz, 7.5 Hz, 10Hz and 12.5 Hz. You have a Band Pass filter and you also have a High Pass filter. Within each type of filter you can select the speed which best suits your swing speed habits.
The lower frequency filters tend to favor slower search coil sweep speeds and the higher frequency selections tend to favor faster sweep speeds. The Band Pass version of each filter speed works better for lower mineral ground conditions and the High Pass filter for higher ground mineral conditions.
What all of this means is just because you have high, medium or low mineralization does not mean you set your filters to this or that. Some hunters like to swing slow and other go like the wind. This filter selection system lets you adjust filtering for each personal preference. An easy way to set up which filter works best for you is a test coin in the ground, swing your coil the way you normally hunt and try each of the 8 selections. The best audio and depth is the one you should use.
