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

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

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

Astoundingly bad quality control to deliver this to me with the obvious problem of missing a blue tester end (and instead having 2 green ones). However, this product functioned well otherwise and helped me track down some coax cables in my house.

The product dont satisfy my needs, It didnt work in ours CATV system.

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

Whether you work cable or just diy at home this tool is your best friend. You can zip tie the caps to the back of the tool

Works as described

Handy tool to have when your in The coax world. Mapper, toner,shorts

Works very well in identifying which line was which, and identifying a wiring problem.

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.
