<p><strong>I was detecting for about eight hours on Saturday and hit about 5 spots.</strong> The first four spots which lasted about 7 and half hours produced nothing. Until I got to a local park and dug a 25c reading about 6 inches down and it turned out to be a 1795 Liberty Cap Half Cent worth upwards of $550!!!!! I was using my Spectra V3i. Thanks for making such great products!</p>
