I'm new with the pictures thing, and this is from the Xoom so let's see what happens. I have attached a picture of the coin finds for the past 25 hours. Every one of these was found with trash in the same hole, usually iron. I was once concerned about coins getting discriminated out with nails but found that is not the case. The 4800 will give a good signal on bent nails, double nails, a nail with anything, short bolts, nuts, flat washers, and winged nuts. Pull tabs, pop tops, and foil balls always give a good strong signal too. Most of my targets have been 10" or less and the response is almost always low high low. I have not seen enough of the high low high response to understand when this will occur on coin sized targets. I run the dd coil with iron mask at 10 and sharp soil timing. Any advice from some of you veterans? Thanks, Rick
