Supersonic Air Knife and Soft Dig Tools
The Supersonic Air Knife is the solution for digging around buried utilities and non-porous material that you want to keep safe during excavation. Shovels, axes and picks can damage fiber optic cables, ducts, pipes and other buried utilities with very little force. The amazing air knife acts as if it were a small charge of dynamite in the soil, but the air traveling at supersonic speeds diverts away from solid objects in the ground. You can even point the air knife at your shoe and it will not hurt your foot.
