At what point did you start cherry picking and leaving the penny signals? Been there and done that many times....too many targets.....just give me the good ones!
As I`ve said on here before. I ONLY go out on weekends to avoid people/workers at schools parks etc. Most times im up and out by 5am. I love going out in the rain also for this reason as nobody is gonna bother you or be out to bother you for that matter. I have NEVER been bothered by anyone in all my years of detecting and I credit that with picking the right time and places to hunt.
