I was out hunting this morning using single frequency. I was using 7.5KHz as many users report good depth at this frequency.
I got a a good solid hit with a VDI of 75 at about 4 inches deep. Because in the past I've dug a number of bottle caps I thought were quarters when hunting in single frequency, I decided to check this dime using three frequencies. To my astonishment, the signal changed. The VDI now read 47!! I changed back to single frequency and the VDI returned to 75.
Upon further examination, I realized that in three frequency mode, the Spectragraph was showing the 7.5KHz frequency at a VDI of 75 while the other two frequencies landed elsewhere.
So how does the machine come up with the 47 VDI in three frequency? I was using Best Data.
The rest was: Stock C&J. RX=10, AM=75, DISC=92. 10.5KHz band filter. All VDI's accepted
As it turns out, I never did find out what the target was because my propointer quit working and that distracted me from the signal. But I will investigate this further.
