My goal in hunting is to find gold and platinum. I could care less if I find coins or silver jewelry. At the present time, the CS-7 is the deepest going machine on items in what I call the gold range. The gold range does include nickels and pulltabs. I have dug a large number of pulltabs 12 inches or more. But you have to do this to get the gold. But since you can determine with the CS-7 using the Frequency control if the target maybe be gold. You don't have to waste your time digging iron of fair size and coins except for nickels. Don't get the idea that the CS-7 is the perfect machine. It is not. I do not like the rod assembly that came with it. Too heavy, so I use a White's upper S rod assembly. I also mounted the conrol box on the S rod assembly. Next, I have a very bad hearing problem. So I change the head phones to the White's Surfmaster headphones to get the volume that I need to hear the faint deep ones. Over here in Hawaii, we spend a lot of time working the edge of the water. The CS-7 will false some then. To fix this problem, I connected a wire from one of the screws on the battery compartment. I run the wire down a long the coil cable and end the wire around 3 inches from the top of the loop. The other problem due to submarine radios. I can only run the CS-7 at the maximun Frequency control position one day of the week. That day I hunt areas where the sand is very deep.
