Great tool

Good tool

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.

This works exactly as described. I was able to trace back 12 different coax feeds from the distribution splitter to each TV hook up -- and it took less than an hour! I also discovered a splitter buried in my attic that was the reason why my antenna signal was weak in just one room -- the splitter looked like a nail went through it. I have 12 TV hook ups and am only using three (do I really need 2 hook ups in the dining room and 4 in the living room????). I debated getting a distribution amplifier, but this was much less expensive and the distribution amplifier would have been overkill as I really only wanted to isolate the 3 hook ups I use. Even though I may not use this again for a while or often, the low cost made this worthwhile for me.

Its a handy tool if you routinely troubleshoot coax systems. This is about as bottom of the line as you can go, but it is simple so gets the job done. Probably the most lacking feature is the receiver caps dont store on the tester body, the store in a separate piece of foam. Mine showed up with dead batteries, as others have indicated. Amazon provided no product support other than a full return, and Southwire did not respond to my support request. I recommend buying from a company that can reliably supply batteries and/or customer service (pick at least ONE please, Southwire). In summary: Cheap product that will do the job , but expect to have to buy batteries on day one and not get any post-sale support. 2/5

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

It would be helpful if you offered the Red,yellow,blue and green id remotes by itself. 2 of my I’d remotes aren’t working so I have to buy a whole new tester just to get 4 new ID remotes.

Saved me some time trying to figure out what the dish people did outside

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

Ive been using this in the geld for a few weeks now, and it is great. Couldnt give it a full 5 stars as one of the tracer caps pulled apart on its first day and I had to put a dab of blue locktite on it. But other than that its been invaluable for those houses /businesses that seem to have endless coax cables going everywhere.
