- Your search window is limited to May 1 through October 15
- Recovered items must be presented to the property office
- Items not belonging to you stay with the property office

Your DNR permit restricts you to a defined location on a specific DNR-managed property, and you can only use it between May 1 and October 15.
You’re not free to roam the property looking for coins or relics — the permit exists solely to help you recover a specific lost personal item.

Dane County Park Rules for Metal Detecting Near Franklin
If you plan to metal detect in Dane County Parks near Franklin, you’ll need a permit before you start. The county issues one-year permits, and you must carry your permit card while detecting. Private property rules don’t apply here—these are county-managed lands with strict conditions protecting historical artifacts and archaeological sites.
Key rules to follow:
- Detecting is prohibited at known or unknown historical or archaeological sites
- Only probes and small diggers under 12 inches long and 2 inches wide are allowed
- Water hunters must display their permit on a vehicle dashboard
- Several state-controlled lands maintained by Dane County are completely off-limits

Probe and Digger Size Limits in Franklin-Area Parks
Whether you’re detecting in Dane County Parks or ranging into Marinette County’s managed lands, the rules on digging tools differ by jurisdiction—and ignoring them puts your permit at risk.
Dane County limits you to probes and small diggers no longer than 12 inches and no wider than 2 inches unless you’ve secured written approval.
Marinette County is stricter—you’re restricted to a probe like a screwdriver, no wider than 3/8 inch in diameter. Shovels, trowels, plug cutters, and knives are prohibited there entirely.
Both frameworks reflect cultural resource protection priorities, keeping surface disturbance minimal to preserve subsurface integrity.
Practicing proper metal detecting etiquette means respecting these limits without exception. Smaller tools protect your permit, protect the land, and keep detecting access open for everyone.
Sites Where You Can’t Detect No Matter What
Knowing your tool limits matters, but knowing where you flat-out can’t detect matters more. Certain sites are permanently off-limits regardless of permits, skills, or intentions. Trespassing on private property or disturbing historical artifacts carries real legal consequences.
You can’t detect at:
- Recorded archaeological sites without DNR archaeologist approval
- Reported burial areas, which are essentially permanent no-go zones
- State-controlled lands maintained by Dane County Parks, including Capital Springs Recreation Area, Salmo Pond, Pheasant Branch Conservancy, and Fish Camp County Park
- Known or unknown historical or archaeological sites within any Dane County parkland
- Private property without explicit landowner permission
Violating these boundaries risks permit revocation, ordinance citations, fines, or permanent loss of detecting privileges. Respect these hard limits and your freedom to detect elsewhere stays protected.
Fines and Permit Revocation Rules for Franklin-Area Parks

Marinette County takes a similar stance, issuing fines for non-compliance. These consequences exist because metal detecting etiquette and park visitor safety aren’t optional—they’re the foundation of your continued access.
If you dig improperly, detect in restricted zones, or ignore posted rules, you risk losing the freedom you’re trying to protect. Carry your permit, follow tool restrictions, and respect other visitors.
Authorities track violations, and one bad outing can close the door permanently—not just for you, but potentially for the entire detecting community.
Violations That Can Get Your Franklin Detecting Permit Revoked

- Detecting within known or unknown historical or archaeological sites
- Using oversized digging tools exceeding 12 inches long or 2 inches wide
- Failing to carry your permit card while actively detecting
- Removing items belonging to other parties instead of reporting them to the property office
- Operating outside your permit’s designated search area or approved seasonal window
Stay disciplined, follow the boundaries, and you protect both your permit and your freedom to detect.
