Ditch Witch 720ML electronic locating system

The Ditch Witch 720ML electronic locating system is designed to detect metallic or ferrous objects such as marker stakes, manhole covers, valve boxes and cast-iron pipe around excavation and horizontal-directional-drilling jobsites. The 720ML has only two controls, located at the base of the display housing, and thus allows one-hand. A digital bar graph displays signal strength and polarity to help pinpoint the target, and the tool provides a choice of two audio modes. Four sensitivity settings allow adjusting the 720ML to soil conditions. Two 9-volt lithium batteries power the 720ML for more than 60 hours of operation.
