Spare Batteries for a Day-Long Tract Walk
A dead GPS in the back of the parcel is a long walk out.

Why this comes up
A dead GPS in the back of the parcel is a long walk out. Pack the spare cells in a pocket, not in the truck.
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 Garmin GPS batteries when that is the job in front of you. Pack the spare cells in a pocket, not in the truck.
The limit
A handheld GPS gets you back to the truck. It is often several meters off, so it cannot tell you where the legal line is.
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.
