What are the settings on a Vari-Nozzle?

Explanation:
The key idea is knowing the complete range of spray patterns a Vari-Nozzle can produce. A Vari-Nozzle can be adjusted to four distinct spray patterns: Straight Stream, Narrow Fog, Wide Fog, and Medium Fog. Straight Stream gives a solid jet for maximum distance and penetration. Fog patterns—Narrow Fog, Medium Fog, and Wide Fog—offer cooling and exposure control, with Narrow Fog being the more concentrated option for greater reach than Wide Fog, and Medium Fog providing a balance between reach and cooling. Listing all four settings covers the nozzle’s full capability, which is why that option is the best choice.
