-For finding the bigger roots
-The sound travels faster in the roots than in the soil
-This measurement is not disturbed by other trees' roots or pipes
-Available as independent equipment and as extension for ArborSonic 3D package as well
- Put the rectangular sensor (the one with the long cable) on the tree. The spike should point towards the roots.
- Connect the BNC connector to the (black) amplifier box.
- Connect the soil sensor (cylindrical) to the amplifer box.
- Tie a loose rope around the tree. The rope will help you to keep a constant distance between the tree and the soil sensor. Move the soil sensor around the tree by small steps, making sure that the rope remains tightened.
- Make a measurement at each sensor position.
