I got a call from a lady who said last night they were having a bonfire party and her son lost his wedding ring. She called me and I came over and within 5 minutes of searching using my garrett AT Pro, I found the ring up close to the fire pit were they couldn’t rake the grass. There was a ton of electrical interference so I had to turn my senitivity down to 3 and there was a bunch of aluminum candy wrappers, so it was a challenge, but I looked for a white gold signal which is around 40 to 43 on my machine and there it was shining up at me. The lady was very happy! as was I.
