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

Too worked well while it worked. Last about a month of daily use before the testers pins no longer made contact with the cable pin

If you have a pre-wired for coax home, and the cables aren’t marked, this tool will find which ends terminate in each room. It also will test a cable in a loop, for continuity.

Works Great and is small enough to keep in your pocket!

If youre trying to test coax, or decipher a rats nest of cabling, this thing is essential. Being able to locate and identify 4 cables at once is amazingly helpful. Great price as well.

Work Perfect!

This devices saved me time and money! I Purchased a dish tailgater satellite for my RV and could not get it to work when connected to the RV. I had two choices. One, take it into the dealership and leave it with them for three weeks or two, purchased this device and test continuity on all the RG6 cables. I’m happy to say that after about an hour testing all the cables I was able to identify where the problem was. Now my satellite is working as intended.

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.

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

Works great...

Great tool
