I'll just say, I'm not a huge electronics guro like many of you are, I just like to dig in the dirt and find the shiny stuff. I have heard that the lower frequencies like the low frequency modes on the V3i and E-Trac are best for finding silver. I have also heard that some of the older White's machines ran low frequencies around 2-3kHz. So what do you all think? Where I am going with this is thinking of buying an older used White's that runs at a low frequency to have as a second machine because I can't afford the top machines. The idea being to go over some of my sites that I have already cleaned out much of the trash from, hoping to find deeper more elusive silver targets. So any thoughts or input from all you folks on that? Thanks in advance for any input!
