Magnetic Locator for a Buried Survey Pin
Iron pins sink. A magnetic locator hears them.

Why this comes up
Iron pins sink. A magnetic locator hears them. Sweep where the deed or plat says the corner is, on your side of the search.
What to check on the map first
County GIS lines are assessment maps. They are not a survey, and a product will not redraw them.
Open Platbookmapper and choose the state. The directory sends you to the county viewer. Match the parcel ID before you trust a pin on an aerial photo.
A tool that matches the job
Shop the Magnetic locator when that is the job in front of you. Sweep where the deed or plat says the corner is, on your side of the search.
The limit
A flashlight or a laser measure helps you look. Neither one is a survey, and a bright beam does not move the line.
The county viewer is the map. The product is only the tool you carry.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
