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

Works great...

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!

Does exactly as described. My house has the coax cable in home run configuration. There are 10 or so coax cables in the attic. Put one of the color plugs at one end, then plug in the tester on various coax in the attic until the tester lights up with the color you are looking for.

So far its been good. Tones out aos well. Only problem Ive had with it is the blue toner isnt recognized anymore by the toner. So now I can only use 3 out of the 4. Ive tried resetting the batteries. Nothing still. The other 3 still work

It worked the first time I used it and then would not work when I tried to use it again.

Not bad

best brand for toners, all other brands i’ve tried have been faulty.

Good product. Value for money. Easy to use

Used it once, worked fine. A few weeks later, wanted to use it again, batteries are dead. Bought new batteries, worked fine again, a few weeks after, batteries are dead again. At this pace the cost of batteries are higher than the tool itself.

Excellent tool! It helps a lot by saving time and effort trying to determine which cable goes where. It works perfectly and is very easy to use.
