I'm sure all of you experienced detectorists are aware of this but I learned a valuable lesson about gold. I have to admit that I stumbled upon a gold earring purely by accident in a parking lot. I'll take gold any way I can find it! The point is I had never found a piece of 10K gold with my detector so I decided to drop it in my yard so I could run my AT Pro over it. I was appalled to find it toning out in the iron range (34 - 3. Since I've been going crazy at this park I am detecting, with all the signals I've been getting, that I've been ignoring the iron signals. WHAT A MISTAKE! Thankfully, no one else is detecting in the park so I now have the opportunity to go back over where I've been and dig EVERYTHING. This is only my second year detecting and I'm learning valuable lesson along the way.
