This pair of high-impact yellow rain gauges can be used together or separately. The base unit has a stake for use off the ground to gauge sprinkler or field watering levels. The larger, five-inch-capacity rain gauge has a hang hole for use on a fence post. One and a half inch, spiked-base water gauge measures field or lawn watering (up to one inch). The six-inch rain gauge measures rainfall up to five inches. Bold black readings are in both inches and centimeters.
