The Spray-Mate II console records the number of acres sprayed, application rate, ground speed, distance traveled, and total volume applied (figure 5). The console is relatively small and easy to mount out of the way on the ATV handlebars. The console can control up to three separate boom solenoids. The applicator uses a single selector switch and four pushbuttons to input all calibration numbers, select the desired output data, reset the console, and select auto or manual modes.

Calibration and output units can be displayed in the English or metric system. The liquid crystal display is relatively easy to see in direct sunlight, but a visor over the display would be a nice addition. The manual does a good job of covering all the procedures in the proper order, but the task of entering the initial calibration information is slow and tedious.

application rate using information from the flowmeter and GPS speed sensors.
Other functions that can be displayed include speed, distance, acres sprayed,
and volume sprayed.
