Coaxial (Coax) Pocket Continuity Tester (Tracer) with Voltage Toner (Sound) and Barrel Connector Bundle, for Testing, Labeling, and Identifying coaxial Lines - Pocket Toner

once you get it apart its a breeze. had to use plyers to get the end loose from the tester.

This is a great pocket toner. Very easy to use and understand. You separate the speaker from the bottom and you attach the top part to the wall Jack or the end of a cable using a barrel then you go to the other end were all the cables are and you stick the little speaker on the cable ends and wait to hear it tone. When you hear it tone you know you have the right cable. Can also be used to identify a cabke connected to any power source.

I am sorting out some coax cabling under my house because while there is plenty of coax, most of the lines are not connected. I was able to use this device to match up the cables to correct jacks. Simply unscrew the bottom off of the Coax Continuity Tester that has the speaker/microphone screen looking tip. Then screw that piece into the coax cable jack in the room you are trying to identify. Then take the other portion of the device (the piece with the light on it) and go to the other end where all of your cables terminate (in my case they are just laying under my house). By process of elimination, start connecting the device to all of the cables until you see the light come on. Once it does you have found the correct cable for that jack.

I have not gotten a clear response to a question about this, but it looks like it doesnt work well through splitters. It seems to be just a DC circuit tester, but I really cant tell. Ive got cables in my RV that I know are connected and quite possibly through a splitter but this device shows the circuit as being open.

Simple, inexpensive - perfect for me - a homeowner with coaxile running through our new house and I needed to figure out what wire went to what room

I used to work for a cable company. I bought this to trace the lines in our Travel trailer and found the tv lines in there to be hooked up wrong. All tv connections inside and outside work now

Works great! Let me know which piece of coax was bad under my house instead of replacing all of them!

Handy

Products work great

Served its purpose of allowing me to trace cables from the attic to the various rooms they go to. BUT man could it use some instructions other than just a B&W image of the products. It took me a while to figure out that I needed to separate parts of it to use it - I thought something was missing from the packaging, but it wasnt.
