I always hunt in all metal mode. I use my ears and listen to what the detector is telling me before I even look at the screen. I've dug some of my best finds that I was 99% sure would be iron trash but still had an interesting tone to it. The cannon ball had part of it showing above the ground and was a large iron overload. On the X-Terra's larger iron rings up 46-48 which is max segments for the machine but has a scratchy sound. Hope that explanation helps.
Cool. Thanks. So hunting in all metal, you scrutinize the tones. Makes sense to me. I've always wondered what good iron relics I've missed. My T2 and AtGold would excel at this. The etrac not so much unless I ran it in ttf. Thanks again.
