MARSHALLTOWN Masonry Line, Twisted Nylon, Fluorescent Orange, 1000 Foot, #18 Line Size, Masons and Archaeology, ML588

Using this to mark my property lines after surveyors marked the corners. I then drive in fence posts. This line is very easy to see at a distance and holds up taunt over long distances.

In my archeological surveys, I use a lot of string to set up dozens of 1 meter units. The strength is perfect, the color usually keeps students from tripping, and it can be re-used for a couple of seasons. It's well worth it.
