State Park Metal Detecting Quick Reference Card

1. Pre-Trip Permit & Rules Checklist

Before packing your gear, verify these four essential questions:

State Rules: Is this park on the designated allowed list or does it require individual permit paperwork?
Permit Document: Do I have a physical copy or active email confirmation of my permit?
Depth Limit: What is the legal maximum depth limit for targets (usually 6 inches)?
Antiquities laws: What is the age threshold (50/100 years) for protected state property?

Cut grass plugs cleanly to ensure root survival and grass regrowth:

Step 1: Cut a three-sided horseshoe shape around the target. Leave the fourth side intact as a hinge.

Step 2: Use a plastic sheet or drop cloth next to your hole. Put all loose dirt directly onto this sheet.

Step 3: Fold the plug back. Pinpoint your target and extract it cleanly.

Step 4: Pour all soil from the sheet back into the hole, leaving zero loose dirt on the surface.

Step 5: Fold the plug back down. Step on it firmly to pack it back into place, ensuring it is flush with the lawn.

I will respect natural resources, historic ruins, and prehistoric heritage.
I will fill all digging holes, pack them down, and leave no trace of my search.
I will collect and pack out all metallic trash I dig, helping to keep the parks clean.
I will carry my permit in the field and comply with park rangers' instructions politely.
I will report any historically significant objects to the park management.
