Enabling a single operator to create a 30-inch-deep pothole in as little as 30 seconds, the Viper hydroexcavation tool from Ring-O-Matic uses cyclo-jet technology for fast pothole excavating. The design of the vacuum shroud and orbital nozzle action keep the nozzle a minimum of 4 inches from utilities while the orbital nozzle action exposes them. The shroud minimizes the operator’s exposure to jetted mud and debris. Containing dirt and mud this way reduces site cleanup time and cost after potholing has been completed. 800/544-2518; www.ring-o-matic.com.
