Metal detecting is NOT allowed on any ball fields, playing surface and/or dog areas. Plants may not be dislodged or have their roots disturbed. Metal detecting can’t interfere with other on-going park activities. Any solid-faced digging or probing tool cannot exceed 12 inches in overall length and 3 inches in width. Any sand digging or sifting scoop cannot exceed 12 inches in overall length and 6 inches in width. Suction dredges and grappling hooks may not be used.

The parks department staff shall have authority to evict an operator for failure to comply with these rules.
2. The state rule also applies
Only on designated beaches at eleven state parks, with a free annual registration and during set hours – under park division policy, which the regulation adopts. On Department of Conservation land, a different agency, digging or excavating is prohibited outright and cannot be permitted.
