Not yet but it looks perfect to go fishing and even better if u have a boat

The use of metal detectors is allowed in certain designated areas in Florida State Parks. Metal detectors may be used at coastal parks between the waterline and toe of the dune, as determined by the park manager, except at archaeological sites within the zone. Metal detectors may also be used during authorized archaeological research projects, and to recover lost personal items, with supervision of a park staff member. Please check with the park of your choice for special details and arrangements. https://www.floridastateparks.org/index.php/plan-your-visit/faqs
