Created with the avid DIYer in mind, SightLeveler is a simple and affordable tool for general leveling projects.
SightLeveler is perfect for many situations:
Establishing drainage slopes
Leveling fences and post tops
Plotting contour lines in the landscape
Swimming pool installations
Simple to use, just activate SightLeveler and align the crosshairs. The object in the crosshairs is at the same elevation as your phone. Add a level rest of a known height and you have a tool to measure and mark level anywhere.
