Went out to the local, OLD fairgrounds area and found a Mercury dime with the Etrac. Yesterday, from the same location, a silver '43 washington quarter. Two merc's in the front yard of an old home a few days ago. I have not had this unit long, and it is finding silver when I thought my silver-finding days where over. Silver dimes ring out at 12-45 on mine but today, I only saw 12-45 once as I slowly and steadily swung over the target. To my knowledge, there was no other target down there with it but who knows. It was an OLD parking lot that has grown up with grass. The grass being mowed year after year for 60 years as formed about 5 inches of soil ON TOP of the gravel. The silver (and the copper pennies and some clad dimes and quarters) are resting just beneath the gravel AFTER I remove the plug of sod from the top. The Etrac is truly a silver loving machine and the proof is in my ever-rising silver coin cup!!!! I like those steady hi tones. I have gotten to where I hear them in my sleep. Merry Christmas all!!!
