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

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.

Did the job easily without a huge cost

Worked as advertised. Simple and easy to use

really easy to use. was able to quickly map out a home and figure out where is my internet coming in

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.

Easy use, functions as expected and it was less than the retail price. I was able to trace and repair a problem with the coax behind our walls caused by a bad install previously.

I just upgraded my old house, I am the third owner, to be MoCA enabled and needed to verify the COAX was intact. As all of the old satellite dish cables were run to a utility room, I did not know which cable end belonged to which room. This 4 at a time check was all I needed. Nice product for your MoCA upgrade

Button batteries were dead. I had to order new batteries

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.

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
