A 6 Joule Pilodyn unit with 2.5 mm diameter pin was used to inspect CCA treated eucalypt poles, suspected of suffering groundline soft-rot decay. Pole plugs were removed at the inspection region and the amount of soft-rot decay present determined microscopically. High correlation (R² = 0.73) was obtained between the amount of soft-rot and Pilodyn pin penetration. The Pilodyn is recommended as a useful instrument for inspecting eucalypt poles.
