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

Good product. Value for money. Easy to use

This is the best mapper Ive ever owned. Ive tried them all and found myself repeatedly buying more mappers every year. The one that seemed to most popular was the simple $20* Jonard. The problem with that piece of junk is the batteries dont last a year and eventually you just have to buy a new one because they didnt make it replaceable. This mapper is the answer to that piece of crap. This has equality feel to it with an almost velvet like a grip and a soft button, unlike the Jonard that you have to press very hard and the button itself will hurt your thumb after repeated usage. best of all, you can replace the batteries on this thing over and over.

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

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.

why not use a AAA or AA battery instead of 4 dot batteries...? Youll need your own barrel connector for the cable at each room location. It does do the job for what I needed it for telling me which cable went to what room. But I would not buy this device again nor would I recommend it

You see a wad of cables in a media panel. They are not labeled or not accurately labeled. Which one goes to which room? You will find out with this tool fairly fast. I do satellite installs and use it daily.

I wish the folks who built my RV had used one of these tools. There was a connection that had fallen off of a tee inside a wall and the tool helped me to find and repair the flaw in the initial cabling. Now my aerial works just fine.

Ive been a cable tech for 5 years, Ive lost count of how many toner pieces Ive lost. This is a great kit for beginners or homeowners because it doesnt cost a lot if you lose one or two! Most houses get 1-4 devices installed so this is ideal for my job. If I need to tone 8 outlets, I just do two runs. Works with my old Klein toners as well! This, in my opinion, has a better build quality than the 4 piece Klein toner kit. The plastic is stronger whereas the Klein kit will bend around in your pocket. Great buy!

Used for mapping and testing for which of a dual cable radio is for the the new single cable. Very noticeable if you have a short. Battery has been going for six months after daily use. Do wish you could turn the mappers around and have a male end but thats just me.

Great product I have use this one before and I misplace it so I bought a replacement. While I do recommend this one product it is a little over priced to me.
