Resistograph used by Blade Runners save clients money

Are you worried about a leaning tree on your property? Is there a tree that is looking old and rotten? Blade Runners uses a progressive tool called a resistograph! By using this tool you can make the right plan of action and also protect yourself from a liability standpoint. This can also be sued to assess timber walls , fences and other wood structures.

The resistograph is an instrument that detects decay and cavities in trees and timber. Through resistograph technology, an arborist is able to detect wood decay, stages of rot, hollow areas, cracks and ring structure. The resistograph is an ideal device for estimating tree stability and longevity. The resistograph is based on a drilling resistance measuring method developed by Frank Rinn in Heidelberg, Germany.

As the micro drill enters the tree, the resistance of the wood changes the rotation speed of the drill. These variations are translated into a graph, which looks a lot like an EKG print out. The tiny drilling hole closes itself up without any damage to the tree.
