White’s,

To boldly go where no man has gone before! 

I found this diamond engagement ring May 14th at about two inches while sorting through the pull tabs under a huge Ponderosa Pine in a Salida, CO City Park. This stately pine tree is obviously a favorite beer drinking venue as evidenced by the scores of pull tabs scattered both above and underground under its branches.

I used the built in capability of White's DFX to differentiate between the pull tabs and the engagement ring. Metals respond with different values to different search frequencies. The DFX searches at two different frequencies and displays a third "normalized" 6.6 KHz frequency when activated. Both pull tabs and small gold rings will display a "normalized" AC visual display index (VDI) value of about 20. The 15 KHz, or DC Phase VDI, value of pull tabs is usually in the mid 60"s verses small gold rings displaying a value the mid 40's or lower. DC Phase is a parameter turned on the pro options, shown on the upper right side of the user display, and activated in the pin pointing mode.

I find that I am much more productive for the time I spend swinging a coil when I use DC phase as part of my standard search programs. It gives more target information allowing me to spend less time digging undesirable items. The White's DFX is the only metal detector I know of that has this capability. It simply helps me find more of the good stuff.
