Abstract
A sprinkler apparatus comprises a spray tube configured to move between a first side position and a second side position. The sprinkler apparatus also comprises a first side adjustment mechanism and a second side adjustment mechanism. Each adjustment mechanism comprises markings indicating lesser to greater degrees of sprinkling coverage area. The sprinkler apparatus further comprises a coverage indicator component attached to the spray tube. The coverage indicator component includes at least one window defined therein. The first side adjustment mechanism and the second side adjustment mechanism are independently moveable in relation to the coverage indicator such that the markings on the first side adjustment mechanism and the second side adjustment mechanism are selectively viewable to the user through the window. The positioning of one of the markings within the window results in a related degree of sprinkling coverage area by the sprinkler apparatus.
