The dual displays allow you to track both individual events and keep an annual running total. The dual counter requires 3 "AA" alkaline batteries and two button cell batteries. The button cell batteries are included and will last for several years.

The 8" diameter collector meets NWS specifications for statistical accuracy. Every time the bucket tips, a count is transmitted to the indoor display and the gauge empties. You never have to empty the gauge. Each tip of the bucket shows one hundredth of an inch on the indoor LCD display. Installation to the plug-in counter is a cinch.
