You can easily test for continuity and short or open circuits with the PT-300 (sold separately) - the perfect tool for the job, designed to help identify cables prior to connecting CATV, Satellite or other transmitting - receiving systems. But what happens if you lose the convenient twist-on speaker that is essential for toning? Don't worry - we have a replacement! There is no need to purchase the entire tool when you can continue to use your existing PT-300 for testing and toning.
