IDK…just posting an older thread for the OP that I though might have value, especially the @ rmeier2 post. I posted the thread link: "Wiggy" Line Voltage Tester for Home Inspectors. Not sure if you’re having issues with the link…
I know nothing about the thread and wasn’t involved in the discussion.
Edit: I posted this for the content of the entire thread, not just for the initial OP’s post. I felt there was some good discussion on the topic in the past and thought it might benefit the OP. @rmeier2 as well as other long-time members posted some good info including their preferred “wiggys” and thought it was appropriate to point the OP to further discussion that has already taken place on this forum. @ rmeier2 posted a great link from Fluke that I enjoyed and had never seen.
