Being one of the first in the world to use the thread viewer i am impressed with the development of this tool. The optics and lighting are the best i have used in accessing cylinder threads. USB charging remover the hassle of batteries and the risk of damaging wiring when changing. In my 21 years testing this is the best development on the market and I am extremely pleased I purchased this unit for my business.

The virtual training provided was informative and convenient for students to access the course without needing to travel far or find a classroom for the instructor. I feel that for recertification, the instructor being in person in the classroom is not as critical as when the student is a first time inspector. I hope the virtual training for recertification remains an option in the future.
