Сoverage distance
The maximum range that the sprinkler can provide.
The choice for this parameter depends primarily on the size of the area to be covered. However, keep in mind that a high range usually requires fairly high pressure and can degrade watering efficiency close to the nozzles. Therefore, even in large areas, it is sometimes more convenient to use a system of several sprinklers with a short range, rather than a long-range device.
Max. coverage area
The largest area that the sprinkler can cover during operation (or the standard coverage area for models that do not allow changing the size of the captured area).
The larger the area, the more watering area it may require. At the same time, the irrigation system must correspond not only to the area, but also to the shape of the site. Therefore, a model covering a large area is not always the best choice — sometimes (especially in areas of complex shape) it is easier to cover the required space with a few relatively modest sprinklers.
In some cases, knowing the irrigation area, you can determine other characteristics of the device: for example, for a sprinkler with an irrigation angle of 360 °, you can calculate the maximum range without much difficulty, even if it is not indicated in the characteristics.
Hose diameter
The diameter of the hose (or pipeline) that the sprinkler is designed to connect to, in other words, the diameter of the mounting thread provided in the device. This parameter allows you to determine compatibility with a specific hose: if the mounting diameters do not match, you will not be able to connect the sprinkler directly, you will need an adapter.
Hose diameters are traditionally indicated in inches — for example, 3/4" or 1.5".
