A necessity for cable tracing
Narayana Sah Pawar Venkoba Sah✓ Verified Purchase•October 17, 2023
Great tool to have when diagnosing or running cat.
GREAT VALUE for Occasional Use
Kev100✓ Verified Purchase•September 19, 2023
This seems to work just fine, for occasional use. I only rarely need to trace existing wiring and did not want to spend a lot of money on a device - so"¦.I rolled the dice on this one. However, gladly, it seems to do the job just fine. All I need it for is occasionally locating the right pair (or cable) in a rats-nest of someone else's (tag-less , of course) previous poor installation.
But, to echo a previous reviewer"¦.. just don't drop it.

Works but not as easy as you would think

Overall its a great product, does what i needed it to do and solve a problem for me. However you really need to read the 2 font instructions to understand how to use it. I bought it to specifically tone a coax cable. Got the device, set the dial to "tone" and nothing. Checked other settings, seemingly not working right and nothing. Put the unit on "scan" and i get a tone. No problem ill use it for my needs and return it defective. Fast forward, fixed my issue then decided to read t instruction. No joke on 2 font. i needed my phone to read it. Well low and behold, you get the tone feature my using scan, the "tone" on the dial is to check dial tone on a phone line. After looking over the instructions it does work as they say its just really odd why the settings are callled what they are. Am keeping as it comes in handy and was a good value just not intuitive like any other testing i own or have used.
Good for the price, limited range for tone testing

Good value and functions as advertised. Not great range for tone testing. Fine for a few feet, but not great for long distances. Mine can do 50 feet max with mild shielding on the wire.
