HEAR IT BEFORE YOU DIG!
Tap at the instant the two blue waves meet.
- Watch the two blue waves move in from opposite sides.
- Press “INVESTIGATE” when their centres meet. Ignore the red jagged road noise.
- An early tap can be corrected on the same wave. A missed wave gets one retry on the same pipe.
The field verification measured between two points roughly 500 m apart on pipe up to 1300 mm wide. Accuracy varies with surrounding noise. This unofficial game simplifies the detection idea; it does not reproduce the real analysis.
