While the shovel will always have its place in the excavating business, the Vac-N-Dig Excavator can dig a typical pothole in an average time of 7-8 minutes in all soil conditions-even rocky Black Hills dirt. (Try that with a shovel!) In addition, the Vac-N-Dig providesMvc003s.jpg greater safety against accidentally striking a fiber optic cable, gas pipeline, electric powerline, or water main that can happen with a backhoe, pick or shovel. With its nondestructive, soft-touch dig, suck-and-seek method of potholing, the Dig-Right Excavator virtually eliminates these costs and delays, increasing profitablility for everyone involved.
