A must for drawing sections and laying out short lines on archaeological excavations

Use it with the Stanley line level.

This set comes with two pins and 30 metres of string.

Tie to one pin then wrap the string around the shaft
Attach the other end to the second pin

Pull a tight section string between the two.
Don't forget that Line Level!
