Resistograph

I would second hiring someone to do it. Having someone who does it all of the time and actually understands what the results mean would be more beneficial than renting one and trying to understand the results by yourself. I spent the last two days at a workshop where the inventor of the resistograph was one of the speakers and I learned it would be very easy to misinterpret the data and also easy to misuse the equipment to get unclear data from which you could make recommendations from.

Somebody at the workshop must be able help.
 
Perhaps breaching wall 4? Usually not as impactful as an increment borer however.
Perhaps he was refering to liabilities involved with risk assessment in general?
 
I would actually steer clear of the resistograph. There are much better ways to measure decay in trees that provide a much clearer picture, like any of the sonic tomography products.
If you want to measure resistance I would get really good with a drill and an earplug.
 
Yes a sonic tomography inspection is great but you still need a resistograph or other micro-drilling machine to verify shell-wall thickness (a tomograph allows you to guess only)

So now we are at 21 to 30 k USD for the two devices. I am not lending or renting mine but I certainly work as a subcontractor.
