dear gentlemen, i need help finding a metal detector that doesn't lead me to hotrocks. my target is in a half mile radius and every detector i have tried keeps me digging hotrocks. I have tried the Pro series 11 target max (hot rock and mineral disaster) a whites 10 coil and a german made dragac with a scanner, laptop, visual software worth over 40,000 and the outcome was the same as the Whites. Any advice would be appreciated.
