Got the C$ about a month ago. Went back to the cornfield where it found the 1851 silver three cent piece. British troops camped in the adjacent field but today its rare to find anything there anymore. The two piece button is really small, has the skinny eagle standing on an anchor, might be British, excellent condition. The buckshot was between 6 & 7" deep. The suspender slide was 6". The piece of copper sheet metal is a hair bigger than the quarter and was a measured 10" deep still solidly lodged in place when I measured it. I was impressed with the buckshot at that depth but the piece of copper at 10" gave me respect for the C$. Was using the 10" coil in mild soil, Disc mode, 0 Threshold, and 9 Sensitivity. All signals said "dig" with positive numbers from about 04 to about 15. Dug a lot of deep rusty nails too but learned not to dig if I see any negative numbers sneak in. This detector is easy to use and it goes deep. In the beginning my biggest problem was learning how to store in the 3 memories. Thanks to all the posts on the C$, they helped more than the instruction manual.
