Tree inspection
How healthy is the tree?
Identify early stages of decay
Our tree care and inspection instruments enable early detection of internal defects, ensuring the safety of people and property in parks, alleys, and forests. By identifying potential hazards, you can take proactive steps to prevent accidents and damages.
The VTA method (Visual Tree Assessment) helps to detect defects by outward manifestations of the tree and therefore it ensures the correct application of our instruments. By means of this method (visual assessment) arborists, tree inspectors and experts are able to identify in time dangers due to immanent tree failure. That way they can take the right measures early enough to prevent damages to persons or property.
The measurement methods of our test instruments are scientifically proven. Scientists and specialists recommend them as objective and reliable examination methods.
Frequently asked questions about „Tree Inspection“
Yes, you can take the information from PD/F Tools or WoodInspector and utilize it in your GIS or other related software.
The wood inspection drill measures the force of the needle turning through the wood product. For example, when the bit hits any soft decay the force on the graph will drop and if the needle hits a hard, brittle decay the graph will spike. If the bit runs through a cavity area the graph will drop measuring no resistance for the bit. The measurements are then collected on either a wax paper strip (F-Series) or electronically recorded for an instant upload (PD-Series).
With the F-Series drill the measurements are recorded on a wax paper strip. Typically users scan the wax paper strip into their report reinforcing their assessment of the wood. The PD-Series drill records the measurements automatically in digital form and can instantly upload these results to your computer via Bluetooth or USB cable. Software is available for your computer to analyze and organize your collected results.

As the Manager of Member Services for our Joint Action Agency, I can tell you that Amber and Kevin made the process of purchasing and training on the RESI PD-500 pain free. They are now an asset to our organization along with the pole equipment. I could not ask for a better experience and the drill has performed flawlessly since it was put into service.
We purchased the 400XL for testing trees in our community and so far it is all we expected. Communication throughout the entire purchase has been great and Bob was very helpful in the training of the operations. I was able to use it with no problem the first time with no major issues. Loading the paper was the most difficult.
