I got a call yesterday through ring finders. This ladys husband lost his wedding band in 30 inches of whole kernel hard corn. The crib was maybe 30 feet by 30 feet and 30 inches deep. I got there and had my Deus and a 11 x 13 inch coil. I ran the pitch program and in the XY setting. First target i got was bouncing around 85 to 88. I dug down to the bottom found the bottom tarps grommets. I had brou ght a snow shovel with me to move the corn around so i could get to the bottom .There was grommets all over the place so i would pass on the 85 to 88 readings. Five minutes later i got 56 reading. I dug down about 12 inches and probed with my probe. I finally located and picked up her husbands ring. She was very happy screaming at first then crying. It sure makes you feel great to make people happy !!!
