    How to Play It Safe When Locating Underground UtilitiesWhy Take The Risk?Multiple Active and Passive Tracing ModesThe Complete Solution For Active and Passive TracingAccurately and Safely Pinpoint Underground Utilities Before You DigBefore you break ground for a new commercial structure or residential development, or extend electrical, water or gas lines into a new area, you need to accurately locate buried utilities to avoid risking outages and to prevent potential injuries and fatalities. The first step is to review a utility map of the area if one is available. However, if there is no map or it is out of date, this gets complicated and expensive, so you’ll need to look for other options. If you don’t find out exactly what’s underground before you dig, you may find out the hard way by cutting an electrical, gas, or water line.
