John Blue FM-40 Foam Marker

The John Blue FM-40 foam marker kit assists with accurately spraying your acreage with a boom up to 40′. Most commonly used in golf and turf applications. The kit includes a 4 gallon tank and all necessary hardware. The foam balls generate at the end of the boom and mark where you have already sprayed. This will prevent you from overapplying the chemical and decrease the likelihood of damage to what you are spraying.
