I live in Pennsylvania and am new to the hobby and just purchased a new Fisher F70 and just ran into my first snag, finding good places to hunt that are allowable. Here is my big question that I want to see how you guys interpret. MD is allowed in Pa State Park in certain areas and during certain times of the year in other areas. These are their rules for retrieval of targets in the ground (ie digging a plug): "Shovels, spades, garden trowels, and other similar tools may not be used to dig into or turn over ground areas that are covered by turf, vegetation, shrubs, or trees. Permissible digging tools are screwdrivers, ice picks, and other similar narrow pronged devices." I always cut a square plug under the grass roots, refilled the hole with the dirt when done and tamped the plug down neatly and firmly..., but exactly how does one use a screw driver or ice pick type tool to find the targeted object or better yet get it out of the ground!! I am confused, can anybody help me with these rules?
