Sprinkler nozzle spray width indicator apparatus and method

A sprinkler apparatus comprising:

• a frame;
• a generally tubular shaped housing attached to the frame;
• a nozzle strip positioned inside the tubular shaped housing, the nozzle strip comprising a plurality of flexible nozzles, the flexible nozzles normally positioned in upward direction;
• a cam plate positioned inside the housing, the cam plate comprising a plurality of cam slots configured to engage with and thereby adjust the position of at least some of the plurality of flexible nozzles upon rotation of the cam plate within the housing;
• an adjustment tab attached to the cam plate and extending away from said sprinkler apparatus;
• and
• a gauge window formed in the housing, wherein
• the gauge window is configured to expose a portion of the cam plate such as to designate an extent of angular displacement of the flexible nozzles based on a position of the cam plate viewable through the gauge window,
• the adjustment tab is laterally spaced apart from the gauge window such that no portion of the adjustment tab is exposed from the gauge window, and
• the cam plate is configured to rotate around a central axis of the generally tubular shaped housing.
