Our gun rights where stripped from us pretty easily here in CT and we followed the rules. So following the Rules will get you no where if they want to shut Metal Detecting down they will no matter what you do to try and appease them.
I am not breaking any laws and will detect when I feel like it

We shouldn't have to hide in the shadows if we are doing nothing wrong. Most of the time I hunt at night anyways just because of the endless questions from the people at the beach.
A few post above hit the nail on the head. I travel over an hour to get to the Ocean and I shouldn't have to wait for people to clear the beach to detect the ocean is there for everyone to enjoy. I hate when people Smoke on the beach but they keep doing it and no one stops them.
Is it rude to hunt near blankets? I wouldn't do it. But throwing frisbees and footballs and almost hitting people is rude. Leaving their trash all over the beach is just plain disrespectful but yet they keep on doing it.
I was minding my own business at a local lake and some old retired Teacher decided she wanted to strike up a conversation. Even thou I was polite and chatted with her she eventually got to the reason she was there by asking me "WHY DO I DO THIS?" I kind of half answered her because I knew what she was up to and she asked again "I don't get why you do this?". She wanted me to say I do it for Profit which I don't LOL. Point is no matter what you do there will always be someone to complain so enjoy it while you can.
And how can you change the Publics eye when we have TV Shows putting dollar amounts on the so called Finds they have Found? It is never going to happen. They will never believe you do it for exercise and just plain fun period. I never once sold anything I found everything is in a jug but it doesn't matter to them.
