DataShark Network Cable Tester - Cable Mapper, Check Continuity - Test Patch Cords or Installed Cable Runs

Inexpensive, but fabulous for tracing a maze of undocumented cables. You also need walkie-talkies or cell phones.

My home network has grown into two wireless routers, two switches, three DVRs, an Xbox, four computers... Geez, it didnt seem complex until I thought about it. Ive been having occasional issues with the network, causing me to reset routers and switches, maybe try unplugging and replugging and rebooting devices... Just enough to be annoying, as it worked most of the time. I spent an hour with this simple device and loved it. It doesnt get easier; the source lights up lights 1-8 in order, and if all is well, 1-8 on the box (if a patch cable is plugged into both holes) or dongle (if checking an installed cable) will light up in sequence as well. I discovered 4 of 11 wires and jacks had issues, including a commercial cable I never would have suspected. Lets just say I now have tremendous respect for the magic boxes ability to work even with messed up cabling; having had this network for years, I now dont know how it ever worked. Now, all is well with my network world, thanks to this device. If youre going to buy a crimper and RJ-45 blanks, your next step should be to buy this. Now, I wont even use a commercial cable without testing it with this device. It gives both great results, a tested network, and peace of mind for a reasonable price.

Very nice. Works just how I wanted and in the correct price point. I use it every once in a while but it helps to keep from asking a friend if I can use his. Great investment for cable making.

worked just fine, found error I had made quickly. Worked on a cable + - 300 long. 4 stars because Im sure it had a fault I just didnt detect.

Awesome product. Traced my wires quickly and cheaper than having it come out. Great product for the diy’er

Just what I needed!

Great for running network cables through my house.

Does exactly what it says it will do.

As advertised with a great price

Received as advertised...big help in troubleshooting a neighbors network installation.
