I recently purchased the 9" 3KHz Concentric coil. I then read everything Digger (Randy) posted about this coil. I then took it to the field and was determined to use it in Multiple Target Tones and in all medal as Digger suggested. Perhaps I'm a slow learner but to say I had one heck of a time adjusting to the Multiple Tones is a understatement. I was getting all these tones and was having a hard time telling the difference from a zinc penny to a quarter. In fact I dug several coins that I though were dimes which turned out to be penny's. I then went back to 2 tones and set my X-70 to the coin mode. I hit a solid 36 at 4 inches. I knew this was a dime. I reset my X-70 back to Multiple Tones and all metal. The tone was in the high range and 3 to 4" and 36 was displayed. I dug and recovered a dime. I then returned my X-70 back to 2 tones and coin mode and continued to hunt. My next td was a solid 42 at 6". This would indicate a quarter or larger coin. I again changed to multiple tones and all medal. Sure enough I received a high tone and a 44. I dug and recovered a quarter. The point I'm trying to make is if you are having problems using multiple tones the above approach sure is helping me adapt.

Multiple Target Tones and the 3KHz coil....:minelab:

Tom those are great observations! I haven't tried that approach, but will. I like the "test it" mode you are using. As it is now when I get a good solid tone all around I dig it and should be using your method. Good info....... I'll tell you what I have been doing. A certain place in Barnwell County S.C. gave off different tones and TID's. The reason was not very obvious to me until yesterday. It's a very old place that at some point or other people sat around on the ground watching something, I don't know. But I've found 10 pocket spills at this one place. Most of them are coins just about stacked in one way or another on top of each other. They are touching in other words. Definately different TID and tones. But when I dig, it will be several, up to 8 coins in one spot. As I wave the coil over the target I will get at some point or other a good tone with no warble at all if I wave it in the exact same spot repeated times. Otherwise it might sound a mix of tones and such. Very rewarding to dig then sweep still while on the knees then dig again and repeat. In other words very close examination with the coil before digging. So listen for what very well might be a good tone mixed in with other non identifying tones. I'm still learning like you and love it! Good hunting......................
