Ludwig sensors are intermediate Arborsonic sensors. So if you have a 12 sensor Arborsonic you need 12 Ludwigs and so on.
They enable enhanced geometry and improve the accuracy of the arborsonic 3D tomogram system, sample image shown using Ludwigs shown by the 'L'.
Note longer length available 120mm - See other listing - For thicker barked trees
