Hi Montammie
I have experienced many instances of harassment over the years whilst beach detecting but also many great times.I've had young thugs throwing beer bottles at me,Someone called the police on me one night and told them I was swinging a shotgun.I had a guy run up and grab the detector shaft and start swinging it wildly in front of his mates.But the many nice people far outweighed any issues.Most people showed interest in the hobby or when explained understood the pastime.
Since moving to the goldfields over 7 years its been sweet sailing as there are many like minded people to meet.
