In general, when you lose your signal, we recommend you proceed as follows:
- First go a few meters/feet ahead. The soil may not be compact enough around there.
- Then, if you still have no signal, go back to the latest known signal, and make a circle
around it to check if there is not a curve in the pipe direction
On this illustration, you lose your signal. It drops to 3%. You want to move a little bit farther away
to check if the ground is better two meters / six feet ahead. If you are reading 2%, you can
assume that the pipe is not going in this direction.
After coming back to the last known location, and making a circle, you can usually determine
that there was a curve in the pipe direction!
