Posthole Depth Marker
Exterior, Garden Tools & Supplies, Lawn and Garden, Video by Danny Lipford
A simple, easy way to measure postholes as you dig them is to mark 6-inch graduations up the handle of your posthole diggers (a permanent marker is ideal for the job). A similar approach works well for a shovel handle; only here you can measure from the handle end instead of the blade end so you can invert the tool to measure as you go.
