This A Frame will work with any Metrotech 9800 that has fault locating in the transmitter. These all have very little use and were used as demo models by sales reps. I can say from experience this is one of the most accurate and easy to use Fault locators ever made. Just turn it on and follow the arrows. I trained thousands of people how to use these and thousands of people how to fault locate. Before I retired I was considered one of the most knowledgeable people in the country on how to fault locate. I have 9 of these to sell. The one pictured may not be the one you get but you will get one that I know works.
