MFL. Detachable Advanced Cable Tester Line Audio Finder Black Cables Checker 10-Way Switch Wire Tracker with LED Indicators, Separate Working Mode, Rectangular

The fact it divides in two is so helpful!

The detachable feature is a must for installed cabling. Works as advertised. Note that an intermittent short may test fine because it's intermittent :)

Super herramienta, muy útil a la hora de probar el cableado, el generador de tono facilita mucho el line check, el poder separar el tester es de lo mejor.

One note: the version in the pictures at time of review indicates there is an RJ11 tester built in, which is not the case, the new model now has USB-C to USB-C test capabilities instead. I ended up making a couple RJ45 to USB adapter boards to be able to test all USB cables (works great), and have RJ45 to RJ11 adapters to test RJ11. One could really make adapters to test any other non-included cables were they inclined to do so, as between the RJ45 and HDMI inputs there are many paths that can be used (eight for RJ45 and 19 for HDMI). Just something to keep in mind. Now on to the review... This will test just about any kind of cable found in the home and/or home studio, and it does a wonderful job. The best part for me is that you can detach the two units and test cables in place, not having to pull them from installed positions. This to me is worth the cost premium over the other two units, because I have many (TRS and MIDI) cables in place and wanted to be able to test them without removal should I have an issue, and for that it works great. Luckily I have not had to use it for troubleshooting yet, but have tested some cables before implementing in my setup and it did the job wonderfully.

I purchased this tester for the sound system at my Synagague. It works perfectly. Loved the ability to seperate the two halfs and test cable ends that are seperated from each other. the biggest appeal to me for wanting to purchase this tester was the ability to generate a test tone. Used it to verify proper connection of each input to the snake and back to the board. My biggest issue is lack of a full understanding of how the tester works internally. With the tester connected to a channel I can generate a test tone all the way from channel input all the way to the speakers but when tester is removed channel was dead. Come to find out the cable was bad. If the cable is bad why was the test tone working? I suspect the test tone only generates an unbalanced signal as opposed to a mic or instrument through a DI box. Channel works with an unbalanced signal through a bad cable but a fully balanced signal the broken cable causes an issue. Mistake on my part but the tester really sent me on a wild goose chase trying to figure out the issue

Versatile cable tester. It can test cables that are already laid. High quality. Quick ship. Item as described. I would purchase from this seller again.
