The Champion Sports Pro Dry Line Marker is one of the most durable pieces of field marking equipment available on the market today! This sturdy dry line marker features a single-piece cast aluminum rotor housing and a bucket capable of holding up to 85 lb. of chalk. The unique spring loaded second stage shaker agitator prevents air pockets and caking to produce a free flowing 2in or 4in line. A fintertip control provides instant shutoff while a flow gate and lever stop give you infinite control and precision. Four 10in diamond tread rubber tires provide the ultimate maneuverability and the clutch system allows you to pull the marker in reverse without making a line.
