Decay entering the tree trunk from the ground (or sometimes advancing down from above) creates an air pocket in the removed wood space. The air pocket can be either a total hollow, or a very early stage of decay where the wood consistency has changed but no visible hollow has yet appeared. The TRU system is sensitive to, and can detect, both conditions, including difficult-to-detect early stage decay. TRU can also detect internal cracks and cracks that have progressed to the outer surface, but are not yet visible. Most trees fall over because of compromised roots. The TRU system can non-invasively inspect soils - either covered or uncovered - to provide images of the layout and density of subsurface structural roots. This new, advanced technology represents a significant economic advantage for companies, individuals, and organizations because more accurate decisions translate to less legal liability, more revenue for tree care companies, and higher customer satisfaction. Owning such a powerful diagnostic tool provides a competitive edge to those companies that recognize the benefits of this cutting-edge technology. |  Damage from trunk decay.

By definition, a hazardous or high risk tree is one with a high likelihood of falling onto a "target". The target can either be nearby people or property.For the homeowner, property values, in many cases, are often significantly affected by the size and health of trees on the property. TRU provides a method for assessing the health of the trees, a valuable asset in the buying/home inspection stage.
