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

Tests continuity of cables with a nice and loud signal (alarm) when you have continuity. I used mine to isolate which cable was which from about 14 different cables all in a panel. Worked easily and worked well.

Only complaint is that it came without any instructions what so ever.

Works great for determining whether the cable is live or not. Easy to use.

I usually use a Klein scout to tone/test coax but this tool comes in handy for toneing wires quickly. The press on connection makes it a breeze to click through multiple wires to find the one your looking for. It doesnt replace a full blown tester/generated but at the price its worth adding to your tool bag.

After months to figure out which way the 6 coax cables went in my RV and which. Able was satellite, cable or over the air it took me ALL OF 20 min to solve the puzzle

It does what it is supposed to do. Only drawback is that the plastic case it comes in does not have a lid to keep everything from falling out. Not a tool that can just be tossed in your toolbox for later.

For anyone that is tried to figure out which wire is which, this is a no-brainer!

Right-angled connector detached from main body and cannot be used. This head connector should not have come off. To salvage from these parts, with pliers, the bulb and the tiny board where it’s attached can be pulled out. Replacing the connection from the detached head connector to the battery by soldering a new piece of insulated wire, the cable connectivity test can be done with the speaker as intended on a short coaxial cable and the speaker beeps. However, when used for testing coaxial cable in house, the tester does not work! The speaker does not beep. Probably total resistance from coaxial cable and speaker is too high and there is not enough current to drive the speaker. Further cutting the single piece of soldered insulated wire into 2 pieces and removing the light bulb from the tiny circuit board and putting the light bulb in series with the 2 pieces of wires and doing the connectivity test by looking at whether the light bulb lights up works, by not using the speaker at the other end but using a cheap coaxial cap instead (not part of components here).

I have a bunch of Coax cable in a bifg distribution box in the wall. Every room of the house is cbled , but not one cable was marked/tagged. This tool allowed me to do the job quickly and easily at a very reasonable price.. I love it.

I purchased a home that has multiple coax installs. Some active, some not. Unfortunately as they disappear into attic, eaves, walls etc I didn’t know where they went to. Using this helped me identify them easily. I then marked for future reference. Having spent 40 years in communications gave me the knowledge to look for this tool.
