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

best brand for toners, all other brands i’ve tried have been faulty.

I like this product I am a cable technician I use it all the time I love that you could change the batteries

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.

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.

Saves a ton of time testing every wire.

Works great...

Worked as advertised. Simple and easy to use

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.

Works great and you cant beat the Price !

The item is good but dont get it wet. It will not work temporarily. All its color readings are accurate all the time. I wish it would bypass splitters.
