I. USE OF METAL DETECTION DEVICES
The use of metal detection devices is permitted on land under the jurisdiction of the Department of Environmental Protection under the following conditions:
1. The activity shall be limited to surface collection except at beach areas where digging is permitted in sand areas devoid of vegetation. However no collecting or digging will be allowed in areas of sand dunes adjoining the beach area proper. Digging must be done by hand with all motorized devices prohibited. All holes dug must be refilled immediately before the collector leaves the site.
2. The use of metal detection devices will only be permitted when the beach is not being used by the public for other purposes.
3. Persons using a metal detector are required to use a trash apron to store all materials found. The collector may retain articles found, except items of a personal nature such as jewelry and watches, which must be turned into the manager in charge. Any material the collector does not wish to retain shall be placed in a waste receptacle.
4. No specific permit is required at this time.
5. Staff may close any area to this activity for purposes of maintaining visitor safety and/or preserving significant artifactual remains.
There is no metal detecting in Connecticut at these State Park areas.
If you get caught metal detecting in Connecticut parks you can be prosecuted.

Remember, you can metal detect in Connecticut, however, you just can’t dig any artifact that is one hundred years old.
Detecting on State beaches is allowed if you get a permit. Be careful. You need to ask if your permit is just for the beach area. Some States do not allow detecting outside of the beaches even with a permit.
