Ditch Witch has released the 720ML electronic locating system, designed for ease of use and engineered to be extremely sensitive. The unit can detect metallic or ferrous objects such as marker stakes, manhole covers, valve boxes, and cast-iron pipe around excavation and horizontal directional drilling job sites.

The 720ML has only two controls, located at the base of the display housing, so it can be easily operated with one hand. Easy-to-read digital bar graph displays signal strength and polarity to help pinpoint the target and the operator has a choice of two audio modes. Four sensitivity settings allow the operator to customize the unit to suit soil conditions.

The lightweight 720ML can be used for extended lengths of time, and two 9-volt lithium batteries keep it operating for more than 60 hours. The unit also comes standard with a rugged case to withstand the rigors of field use.
