Q: Is using a metal detector legal in Arizona State Parks?
A: In some cases. Arizona State Parks does allow "Recreational Metal Detecting" in areas that are not ecologically, geologically or culturally sensitive. "Recreational" means that if the activity is only for recreation, or a hobby and the area is not disturbed to any great level it is acceptable. If you wish to walk along a developed beach front and dig down a few inches with a spoon in order to recover an item, it's okay. If you bring along a shovel and plan to excavate a large hole then it's not okay. Contact the staff ranger at the specific park you wish to visit and discuss the activity with a ranger to determine areas where it would be appropriate. Of course if at any time the activity crosses over into a commercial venture then it is not allowed. Arizona State Parks realizes that this activity is fun for many people, and we try to accommodate them as best we can while at the same time continue to protect and preserve our resources.
