Triangulation Depth – 50% rule
• Use Broad Peak mode (single antenna)
• Locate the cable, set gain to 100%.
• Without changing the gain setting move locator to one side until
the gain reduces to 50% and mark the position.
• The depth is equal to the distance from the starting position to
the 50% point you marked.
• Return to the cable, ensure gain returns to 100%.
Without changing the gain setting move locator to the other side
until the gain reduces to 50% and mark the position.
• This distance should be the same as the first measurement taken. If not, it is a clear indication of
a distorted or bent field generally caused by signals radiating from adjacent cables.
