ABSTRACT:
The invention relates to a level indicating device including a container or reservoir and a length of tubing extending from the container near the bottom thereof. Narrow, inverted cups are adhered to the sides of the container so that they may be slipped over the top of a stake driven into the ground to provide a firm, stable support for the container while the tubing is moved to different locations to establish a reference horizontal plane.
