Tree Check Sonic Wave Tree Decay Detector Kit
Tree Check Sonic Wave Tree Decay Detector is designed for arborists and urban foresters as a low cost, simple to use, reliable field tool to detect the likely presence of significant decay, cavity or cracks in standing trees. Used properly it can effectively allow you to see inside the tree revealing areas of concealed severe deterioration that if left undiscovered could result in tree structural failure and resultant property damage or personal injury.
Details
How the Tree Check Sonic Wave Tree Decay Detector works:
The tool consists of two sensors that are connected to an electronic circuit board box by simple telephone cables. The sensors are secured with setscrews on carpenter’s awls that penetrate through the bark and slightly into the tree wood on opposite sides of the trunk.
After turning on the device, the user taps the start sensor awl with a light hammer creating a sonic or stress wave traveling through the trunk and at the same time creating an electronic signal to the circuit board box starting the timer. When the leading edge of the sonic wave arrives at the opposite sensor, it creates an electronic signal to stop the timer. The circuit board box displays both the wave transit time in microseconds and a graphic representation of the waveform itself.
The user measures the distance between the sensors, calculates the transit time per inch or centimeter comparing it to an expected transit time for defect-free wood of that species. Longer than expected transit times can be an indication that the sound wave movement was obstructed by internal decay, cavity or cracks.

Easy to use
Simple to setup and and use. Minimally damaging compared to other methods of mechanized decay detection. I think more people should use this tool.
Worth it
I was skeptical about this device. The Tree Check Sonic Wave Tree Decay Detector Kit is super easy to use and gives fast, accurate results. I use it all of the time now.
