Inconsistency

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.

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.

simple to identify which cables in attic go to which room.

Quality tool that allowed me to identify coax cabling in a new house. Installers did not label coax so I was able to id which cables went to which outlets. Found a fault in one of the cables, it was not terminated properly. Worth the price even for a one time (hopefully) use.

Worked well but one of the nodes wasnt toning correct out of box so I returned.

My house was wired with 3 different groups of coax (satellite, cable, security cams), but not very well labeled. This tool made it a breeze to track down which cables at the panel in the basement went to which jacks, and especially tracing down which of the several cables in the junction box outside the house went where. Just plug the 4 color coded ends onto the jacks you want to trace down, then head to the other end of the cable and plug in each cable until a green light shows up next to one of the colored dots, and you have IDd those 4 jacks. Repeat until everything has been identified and you are done--couldnt be easier. I knocked off a single star because the color coded caps store in a foam piece that is separate from the tool itself, which almost guarantees they will get separated at some point. If the manufacturer had molded storage spots for the caps into the body of the tool itself, it would get an easy 5 stars even if it cost an extra few bucks.

Great tool

I work in the telecommunications industry and I have used all sorts or line identification tools and this mapper is solid and at a great price! It just works!

Very helpful for sorting out out cable issues and getting a MOCA network up and running.
