PiCUS - Sonic Tomograph Tree Inspection Instruments Brochure

The PiCUS Sonic Tomograph is used for tree risk assessments in order to measure the thickness of the residual wall of trees with internal defects such as cavities or decay non-invasively. Most often the PiCUS sonic tomograms are recorded near ground level of trees. However,  acoustic tomograms also reveal important safety information about the breaking risk near branch wounds and above ground cavities.
