What equipment is sometimes equipped with end guns?

End guns are commonly associated with center pivot irrigation systems, which are designed to cover large areas of land efficiently. These systems rotate around a central pivot point and use a series of sprinklers to deliver water. End guns extend the coverage area by spraying water beyond the reach of the main line, allowing for more effective irrigation of the corners of fields that might otherwise be under-watered.

Using end guns allows for a more adaptable irrigation strategy and helps maximize efficiency by ensuring that every part of the field receives adequate water. This is particularly important in large fields where different crops might have varying water needs or where the land shape limits even distribution.

In contrast, while drip lines, sprinklers, and hoses may be used for irrigation, they do not typically incorporate end guns as a function to expand their coverage area like center pivots do. This makes the option relating to pivots the most accurate choice in this context.
