I would also like to see this.

Maybe you could tie a string to a gold ring and drag it across the ground in front of the locator to see if it beeps when the ring enters the field, then stops beeping when the ring leaves the field.
If you need a fast sweep, then use a fishing rod with a ring tied to the end of a fishing line. You can make a fast sweep when using a fishing rod.
Same like we do with metal detectors - except use a string so we will know it is not detecting a static field from someone walking in front of it.

Then after showing this, point the locator a different direction and repeat it to see if it works the same at other directions and locations.
Of course, this should be done in an open field where there are no trees nearby or fence posts or other suspicious things like electronic equipment, for example.
