I plotted Manicore VID to Gold ring weight (g) as shown below. I also calculated the correlation (R) between the weight and VID and it was R= .60, which is very high and significant; as weight increases Manicore VID increases. What is really important to note is that the real heavy clunkers are in the same range as CENTS! Dig them cents and perhaps you will hear clunking at the bottom of your scoop.
I also looked at the 2-D image for 7 gold rings in my, errr, my wife's possession. The same relationship applied; as weight increased so did VID. But I found the 2-D image most interesting; when in close range (say 6-8") the screen gave a 2-D circular image of about 2-3mm. HOWEVER, as the gold ring is increased in distance from the coil, the circular image on the display starts to elongate along the horizontal line, and continues to elongate over several inches. At near threshold in terms of detection, the gold ring image fragmented into light colored blobs centered all along the horizontal line.
Just yesterday morning I was detecting a beach at low tide with the Manicore and I recall several instances where I got a near threshold image of horizontal blobs. I passed because I thought it was noise. No doubt deep, but that gold drops like an anchor and soon disappears forever.
My only problem with Manicore is the musical sounds; can't hear the dang things. Only in seawater boost can I hear the signal. Yea, moderate hearing loss. But 800 sounds are better.
Happy hunting
