Handheld GPS in Rain on an Open Parcel
Rain and an open field are when people get turned around.

Why this comes up
Rain and an open field are when people get turned around. Use a unit you can operate with wet hands, and mark the truck anyway.
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 when that is the job in front of you. Use a unit you can operate with wet hands, and mark the truck anyway.
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.
Match the parcel ID on the tax bill before you shop for the field kit.
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.
