Unfortunately not. The effectiveness of Ground Penetrating Radar is affected by many factors including soil type and density, moisture content, mineral content, the size and depth of the target trying to be located and the presence of other existing underground items or anomalies.
An example of GPR’s worst operating conditions would be attempting to find a small target in wet and heavy clay soils.
An example of GPR’s best operating conditions would be attempting to find a large target in dry and sandy soil conditions.
