Southwire M500CX4 Coax Continuity Tester/Mapper, Durable Design, Auto Power-Off, Double-Molded Housing, Easy-to-Understand LED Display, Includes 4 Color-Coded ID Remotes

I like this product I am a cable technician I use it all the time I love that you could change the batteries

Nodes quit working after a couple of jobs cheap quality

I had 10 RG6 cables to identify/map the location ....this product worked perfectly and saved me a ton of time! I would recommend this tester.

At first it didnt work. Got crazy readings, then didnt work at all. Luckily I had extra button batteries that it took. Replaced the batteries and it worked great!

Overall a good product for its price. Helpful for tracking down a cable in a mess of cables.

Worked as advertised. Simple and easy to use

Work Perfect!

Moved into a rental house with some creative coax. No idea what did and didn’t work. Put the colored plugs in the coax connections and within 5 minutes checked all 9 connections. 4 active, 3 inactive and 2 that we’re active but not really good. Just what I needed to know.

Its good

This works exactly as described. I was able to trace back 12 different coax feeds from the distribution splitter to each TV hook up -- and it took less than an hour! I also discovered a splitter buried in my attic that was the reason why my antenna signal was weak in just one room -- the splitter looked like a nail went through it. I have 12 TV hook ups and am only using three (do I really need 2 hook ups in the dining room and 4 in the living room????). I debated getting a distribution amplifier, but this was much less expensive and the distribution amplifier would have been overkill as I really only wanted to isolate the 3 hook ups I use. Even though I may not use this again for a while or often, the low cost made this worthwhile for me.
