<p><strong>Let me start by saying the Matrix M6 is a great machine...</strong> I took it out today for its maiden voyage and it performed flawlessly. I found some great things my first silver a 1923 Mercury dime and my oldest coin an 1895 Indian head penny. My favorite finds of the day were my first round ball and an iron carving which I found at 10". It appears to have a face on each side of it and a hole in the feather for a necklace.</p>
