Firstly I cannot stress how much this unit is relied on during my inspections. There have been so many times that it has found termites in places where I would have missed. It’s great for locating feeding areas so I can treat effectively. And for Pre Purchase inspections it clearly shows activity without needing to prove it further.
I almost feel guilty about inspections pre T3i but let’s not go there.
Once again this unit has been worth every $ spent.
