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 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.

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

Its useful here and there

Gets the job done. Make sure you have some extra barrel fittings because all the colored dots are male connectors. They have no threadings, they slip over the R6 ends and stay put without having to twist it on and off.

SAVED ME A LOT OF TIME. WORKED PERFECTLY.

This mapper saves a lot of time when troubleshooting or doing installations. I lost one of the remotes tho, where can I purchase one? Need the red remote

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.

Nodes quit working after a couple of jobs cheap quality

This is a great tool for identifying most homes for antenna installation. 95% of homes are already wire for satellite or cable and this is the tool to save time and work. Just remember to get all of the colored resistors before you leave.

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.
