Smoother tracking and straighter, more consistent lines. That’s what you can expect from the industry’s best field chalker. Pneumatic tires give you a steady roll with superior balance, and clear line guides make tracking your string line easy. Better lines using less chalk. How do we know this is true? Field tests. We compared the performance of the Streamliner with two other leading models. The result was proof that the Streamliner’s advanced chalk delivery system produced the most consistent, solid line. With all three chalkers filled with 50 lbs of chalk each was used until empty. The Streamliner Dryline Marker easily outdistanced the competition lasting 50% longer than one, and nearly 200% longer than the other.
