Re: Measuring device for height changes
You could use a water level, which is merely a length of clear vinyl tubing connected to a water pot and a measuring stick. The water pot sits in one spot while you walk the measuring stick around the yard, noting the water level in the tubing. Cheap and easy solution. Or, if you've got $25, you could rent a builders level and do the same thing, only this will require a second person to hold the story pole (measuring stick ) while you look through the scope.
