If you are worried about the hassle, then you'll be looking for it. I see what Tom_in_CA says and at the same time, looking at the town/county regs to see if anything is listed will give you a start. You have two responses stating it is legal except for Galveston Island Park, which I would expect. I look to see if there are any town or city regs on their websites about metal detecting, if not, go for it. I did it for the Outer Banks of NC and found that it is prohibited for the area that falls within the boundaries of the National Wildlife refuge there but all the rest of the areas are open. Just check, and go with it if nothing outright says no. Most often some "Lookie-Loo" who either is nosey or thinks they know the law and you are breaking it calls and the authorities have to do something if nothing other than check and see what you are doing. Some may not do anything, other may say scram, if so, be nice, pack your toys up and move on. I don't see jail time and most police, etc. would rather be working something else unless they MD and want to get into a conversation with you about it. Might make a friend and new source of hunts and no hassles, who knows? Okay, enough, off of my soap box and Good Luck!
