I'm just getting into metal detecting, doing a lot of research on what I want and where I can go in the state of WA. But can't really seem to find straight forward answers on things like, can you detect on all beaches say like during low tide? I have found some areas require a form that gets filled out and you carry it with you, but want about areas not list. Are these not able to be searched? What type of parks can I search, I realize this is a lot to ask but I really don't want to issue for others who metal detect. Any help with this would be great thanks
