It can happen, that network plans are not quite accurate or are even missing entirely. Then the pipeline must be located.
If you are sure that the line you are looking for routes e.g., through a field or forest and you actually only need to know the approximate route of the cable, using the Autogain mode of the UT 9200 is ideal.
With this mode you can energize and locate the pipe, but don't have to worry about regulating the signal amplification. It will be adjusted automatically!
The receiver uses a special acoustic signal to show you whether the pipe is to your left or right. You can determine the location of the pipe and cross the area quickly. If a more precise position and depth determination is necessary, you can easily switch to line location mode at any time.
