Coax Explorer 2

Simple device performs invaluable function! I have a nest of coax wires in my new home and am finally ready to wire a cable modem. The issue is, especially for cable modems, you should not split the signal too many times or there won’t be enough signal strength for full internet bandwidth. Using this Coax Explorer, I was able to put the red coax “cap” on the wall plate end where I wanted to installl my modem, then use the tool in my downstairs wiring closet to identify exactly which wire went there. The only downside is that every wire you test must have a coax cable end on it - my electrician left me with just raw wire ends. HD has other tools to easily strip & apply coax connectors, so I got that done quickly enough. Another version of this tool comes with 4 different identifier ends (red in this one, add green, black and blue). For me, one is enough and keeps the price reasonable. If I did it all day, I am sure that 4 identifier ends would save 3 more trips up and down the stairs when identifying wires. Great value for the functionality, and of course, it also tests the wire for open or short conditions.

Klein model VDV512-100 coax tester review. I’m a semi-retired I.T. technician and, while I try to leave cabling jobs to the younger folks these days, sometimes testing cables just can’t be avoided. Mostly I deal in Ethernet cable, but occasionally I have to check out a coax setup in security systems. The Klein VDV512-100 comes with the tester and one remote. The process is to put the remote on the end of the cable and then put the tester on the other end of the cable. Pressing a button on the tester will give you details on connectivity – pass, open, or shorted. You can buy additional remote caps, but only one comes with this package. The testing process is simple and quick and seems to be accurate and reliable. I haven’t had the need to test a really long commercial cable installation but when checking the cabling I have installed in my house the tester doesn’t show any sign of signal denigration on basement-to-upstairs runs. The LED light stays strong. This model tester doesn’t come with an “F” style adapter and, as noted, has only one remote included. Klein does offer an upgraded model, the VDV512-110 which includes a holder with 4 remotes and an F adapter. I’m unlikely to be testing more than one cable at a time so I don’t really have the need for the additional remotes. There’s no case or sleeve included; I carry a “road warrior” tool box that has pockets for testers and such. However, sometimes I just want to toss some tools in a tote bag – and having a slip cover or case or bag is handy for those times and I wish Klein would’ve included one, even if they had to raise the price a bit. The lack of a simple storage bag and the lack of an "F" adapter does lower the value a bit, in my opinion. Of course, you could opt for the upgraded version which Klein offers but, to me, even the basic tool should come with cover and "F" adapter. YMMV. There is a “pen clip” for security the Explorer 2 to a shirt or trousers pocket. Fit and finish of the tester is excellent, and the operation of the push button is smooth (I’ve seen some testers that required undue pressure to get the thing to work). The Explorer 2 comes with the two required AAA cells, which is a nice touch. The thing simply works. Klein warranties the tester for the “normal life” of the tool and, of course, Home Depot offers their 90-day return policy. HTH Regards, Jim

Perfect tool for the task.

Worked well in determining which cable to use in a messy junction box.

Easy to use, accurately test cables,

Product performed as expected

Could have used dual female adaptor to check isolated cables.
