Hydroexcavation nozzles from Water Cannon are rated to 5,800 psi and orifice sizes up to 20. The dynamic 0-degree stream of water spins at 2,000 rpm to form a 25-degree cone pattern that rips through the subsoil to expose underground utilities. The rotation helps avoid damage that can be caused by straight 0-degree static nozzles with an added benefit of the 25-degree cone spray hitting the surface at varied angles to increase productivity. 800/333-9274; www.watercannon.com.
