We use the latest PiCUS 3 Sonic Tomograph.
Sonic Tomography
What is Sonic Tomography?
Sonic tomography is a non invasive form of testing, similar to an ultrasound, helping to determine the amount of healthy wood a tree is producing, what internal defects might be present and where there are areas of decay.
Sonic Tomography is an ideal form of testing over invasive methods such as drilling as it does not cause the natural chemical defenses of a tree to be broken to collect information.
The instrument produces powerful data to assist with tree management.

How it works
1
Select the area you wish to test
Firstly, the Arborist will determine the point at which the test is to be conducted based upon a discussion with you about the concerns you have.
2
Attach the sensors and take sonic measurements
Nails are placed in the trunk of the tree, as a means of transmitting and receiving sound waves through the wood of the tree. A sensor is attached to each nail which receives the sound waves that are sent through the wood of the tree and an electronic hammer is used to tap on each nail to send the soundwaves. The PiCUS records the time it takes for these sound waves to move through the wood to which is analysed by the software
3
Make final calculations
The PiCUS Software is then used to Analise the results and create a 2D tomogram (picture) that shows where the healthy, damaged and nonfunctional wood is within the trunk. This allows the Arborist to determine the residual wall thickness and mechanical strength of the wood. in the trunk at the test point. From here, we can provide you with appropriate managment advice for your tree
