ABSTRACT:
A grade checker is disclosed to include a vertically disposed telescopic surveying rod, having graduations. A line reel is connected to the top end of a reciprocating rod, and a line guide is connected to the bottom of the recirpocating rod. There is a bull's -eye level on the surveying rod/handle to indicate "true" vertical. A line level on the line indicates "true" horizontal. When the end of the line is connected to a grade stake, and the surveying rod is adjusted, the final grade/cut or fill requirements can be determined.
