TWIN PROBE TOOL TO ASSESS WOOD QUALITY IN STANDING TREES
The HITMAN ST300 measures acoustic speed to determine standing tree quality and enable stumpage valuation before committing to stumpage purchase or harvest planning.
Using the proven approach of acoustic velocity, pioneered in the popular HITMAN HM200 on logs, with further advanced technologies the HITMAN ST300 offers direct assessment of stiffness on standing trees.
