Hey guys. I have been metal detecting with my GTI 1500 for about 10 years. Traded it in on a new AT Pro which arrived today. A friend of mine lost his gold class ring about 15 years ago while building a snowman in the front yard of his house. He has asked me to go over to his parents house on Sunday to look for the ring. I have the standard coil and the 5 x 8 DD coil. Since I have never really hunted for anything specific like this, I am looking for advice on how to proceed. Not sure how trashy the yard will be, but I am guessing it wont be too bad, because the house is only about 40 years old. Which coil do you think I should use? Assuming the ring is still there, how deep do you think it will be? I have been told that they have not bought in any new soil or sod since the ring was lost. I wouldn't think the ring would be very deep after only 15 years. Not sure how far it will sink. How do you recommend that I set up the AT Pro? Standard mode? Pro Mode? Zero desc? Iron Audio, etc. What type of search pattern should I use? Any tips will be greatly appreciated. Thanks in advance, Gary
