Setup
Turn on receiver and choose power or radio frequency. Always check receiver battery level at startup.
Technique
Survey the Site
Make a visual check of the site for signs of buried lines such as:
• recent trenching
• buried line markers
• overhead lines that run down pole and underground
• gas meters
• valve sights
• drains or manhole covers
Sweep the Site
Search the site by walking a grid pattern while
holding receiver close to the ground.
NOTICE: Lines with no AC current flowing through them are hard to detect and may be hazardous
because they may still have voltage potential. To locate, turn on an appliance to cause current to flow
and use active search methods.
NOTICE: Keep receiver vertical.
