Latest new development in low-cost spray markers is the CrimGold dispenser which uses regular "off the shelf" toilet paper to make easy-to-spot marks that last for several days, or until it rains.

CrimGold comes in a standard model which handles regular household rolls of toilet tissue (146 ft. per roll) and commercial rolls (500 to 700 ft. per roll). The Super model handles large jumbo rolls of toilet paper (4,500 ft. per roll) and, with an inserted adapter, commercial and household rolls.

"Cost of marking with commercial toilet paper, which is readily available off the shelf, generally runs much cheaper," notes Haven Buob, inventor of the patented CrimGold. With a 100-ft. boom, two rolls of commercial toilet paper will mark 400 to 500 acres, he points out.

The dispenser, which has only two moving parts, cuts paper in pre-set lengths ranging from 1 to 14 ft. long, depending on the amount of ground surface cover. Spray material is used to weigh down the paper strips, driving them into the ground so they "stay put" even in strong cross winds.
