Audio Supply Touts Yellow Box As Effective Tool
Originally developed by Audio Supply to serve the HDD market, the WMS-1B Underground Listening Device (also referred to as the Yellow Box) has proven effective in preventing expensive gas line, water line and sewer line hits.
By monitoring the sound of the drill head it is possible to identify when it meets an obstruction such as a sewer or gas line. This is done by placing a microphone in a nearby manhole to listen to the sound of the drill as it progresses.
The WMS-IB helps reduce the loss of man hours, damage to property and the costs associated with after-hour repairs, in addition to preventing potentially fatal injuries and building a reputable safety history.
Audio Supply offers an extended warranty and 365 day 24 hour troubleshooting and tech support. 800.541.2478, undergrounddrillingsafety.com
