Klein Tools VDV501-851 Cable Tester Kit with Scout Pro 3 for Ethernet / Data,...

This is a really great tester. Having the ability to identify lines when you have a bunch of drops was fantastic. I used it to debug a flaky line that had break near the connector. I could watch the lines drop in and out and identify the issue quickly. The built in remote (ID 1) is detached from the unit and checks phone, ethernet and coax. With this you can verify proper pair connectivity and wire length. The kit also came with 5 identifier units (ID1 - ID5) for both coax and ethernet, but these are only checking wire pair 3-6. I kinda wish they had given ID2 through ID6 and I could have used the main unit as an extra connectivity check, but 5 is better than 1. Unit is really solid and comfortable to hold. The display is simple, but easy to read and backlit on demand, so very useful when in the bottom of a wiring closet. This is a tool I wish I had gotten a long time ago. It takes the guesswork out of small issues and can really save some time for those bigger jobs.

This is a professional tool for Network Cable Tester. Works great. (I used a cheap tool and even it said it's ok, it didn't work). But this is awesome. If it said it's ok, it really works. Test every pin and pont exactly where is the problem. If you want something of good quality and reliability you should by this.

I had used one of these in the past. Great tool for checking network wiring.

The product functions as described and is easy to set up and use. It is very intuitive. For instance, I plugged the RJ45 connector into one socket and the other end into a different socket. I immediately received results indicating a short circuit between wires 4 and 5.

If you do CatIV work as a small business or volunteer as I do, then this is a good tester to make sure your wires aren't crossed / open / shorted without the expense of the least expensive Fluke. It replaces the simple 8 light tester that I used for a year before its purchase. It comes with 4 remote probe identifiers that could be of some assistance if you are terminating several wires before labeling. It will also put a tone on cables for identifying a cable in a bundle, but you will need to purchase a VDV500-123 probe to be able to use that feature. Another feature is the ability to light up a port on a switch. I have not used it to light up a port on a switch nor used it for coax or phone cable testing. I have only used it for a couple of wiring jobs, so I'm not completely comfortable with the features and functions, so I have to refer to the manual. Also, I would have liked for the Internet wiring to be running automatically upon power up without having to press buttons, but this might only be me. I'm satisfied with the features and value and would purchase this again.

Love it. Loaded with features , good quality easy to easy

I needed a good cable tester, but didn't want to spend $350-$500 to replace my old unit. This had all the basic features, cable test, tone, one remote, hub blink, backlight for display. I got the kit with a few additional remotes too for multiple cable scans. So far so good. I've used Klein hand tools for years and the cable scanner seems to be in line with their quality. It is a basic scanner though, and the cost reflects that. Seems to be durable so far, would recommend a case.

While trying to set up a wireless backhaul in my new (to me) house, this tool was super helpful to determine which rooms belonged to which cable, saving so much time. It's easy to use, lights up, and helped ensure a better network in my house. I HIGHLY recommend this tool, as well as all Klein tools!

It’s very good to find the problem and easy to fix it

Great product

It worked for few days, after that always gives Failed POE hight voltage even if the the cable working fine and Fluke device showed the connection is Passed. Also measuring the cable distance keeps changing each few seconds

Muito boa ferramenta, ajuda bastante e é simples de operar. Gosto bastante da marca, tenho um multímetro Klein Tools já fazem 10 anos!

This is a really great addition to anyone doing Cat (x) cabling with lots of useful info, which pins are shorted, crossed, no contact etc. loop back function with toner, 5 mini loop back plugs really assist finding which wires go where on a patch panel. Maybe not high end Fluke quality, but not nearly as expensive and a huge upgrade from the cheapo units found everywhere.
