Up-date. I took it out this afternoon and found many ferrous items: see photo for the 3 largest. I was in Park 2 mode. The manual says this mode will show ferrous targets between 0-15. ID. 43-99 for non ferrous such as silver, brass and copper. The long dog chain IDād at 73, the lever IDād at 82 and the short machine chain IDād at 62. I thought that possibly something else was in the same spots, so after removing these items I swept them again. None of them had another signal at that point. This is confusing. Basically it doesnāt appear to really discriminate. I checked the 3 items and they are all definitely ferrous. I also found a lot of wire and nails: every hit was IDād at 35 or higher. Is this normal?
Out again this evening. A little better Park 2 mode. Found several chunks of aluminum cans, foil etc. they were all IDād around 83. At least it wasnāt ferrous this time. Then I found the items in the photo. All of them were ferrous metal (except the pottery piece). They all scored between 54 and 87. Once the rust gets so bad, does the composition change? Iām struggling with these IDs. Iām not unhappy with the finds. I just want to understand my machine better so that I build a level of trust when using it. I donāt expect perfection. What am I missing?
