Cable testing doesn't have to be a guessing game. If you're running new network drops or troubleshooting an office connection, the first question is simple: is the cable good before you button up the wall? Two very different tools answer that question. The Klein Tools VDV526-200 LAN Scout Jr. 2 Data Cable Tester focuses on RJ45 data cable verification. The Network Cable Tester RJ45 RJ11 Wire Tracer Toner combines continuity checking with tone tracing, so you can also locate cables hiding behind drywall or under carpet. Your choice comes down to how much of the job is verification and how much is hunting.
Quick verdict
If you mostly terminate and test RJ45 data links, the Klein Tools LAN Scout Jr. 2 is the practical pick. It is a dedicated handheld data cable tester from Klein Tools, it covers the cable categories you are likely installing, and it carries the lower listed price. If you find yourself tracing lines in walls, ceilings, or patch panels, the RJ45 RJ11 wire tracer toner justifies its higher price by bundling a probe, a remote unit, and support for both RJ11 and RJ45.

Where the Klein Tools LAN Scout Jr. 2 wins
The Klein Tools VDV526-200 is the simpler, more focused tool. It is designed for RJ45 data cables. That makes it a natural choice for network installs where your cable type is already decided and you need a quick check before terminating or after punching down a jack. The compact form factor means it travels well in a pouch, so it's easy to keep close when you are moving between drops.
Where the RJ45 RJ11 wire tracer toner wins
The Network Cable Tester RJ45 RJ11 Wire Tracer Toner does more than verify continuity. It supports both RJ11 and RJ45, so you can use it on phone lines as well as network cable. The built-in toner sends a signal that you can follow with the probe to locate wires in walls, ceilings, and under carpets. The detachable main and remote units let one person test both ends of a long run, and the kit includes batteries, a storage box, and a manual.
Klein Tools VDV526-200 LAN Scout Jr. 2
If your work is mostly data cable verification, the Klein Tools VDV526-200 LAN Scout Jr. 2 is the one to grab. It is built around the RJ45 connectors used in CAT5e, CAT6, and CAT6A networks, which matches the cable types you are most likely to check on a data install. The handheld form factor makes it easy to carry from drop to drop, and the tester is ready for the kinds of cable runs you find in home and office networking. The trade-off is scope: the LAN Scout Jr. 2 stays on the data side, while the RJ45/RJ11 wire tracer toner in this comparison adds a locating probe. If your work also involves finding cables inside walls or under floors, that added capability is worth considering.
Network Cable Tester RJ45 RJ11 Wire Tracer Toner
When the cable is hidden, the RJ45 RJ11 wire tracer toner earns its keep. Its RJ11 and RJ45 ports cover both phone and data lines, and the sensitive probe helps you follow a signal to a specific wire in a bundle or behind a ceiling. The detachable main and remote units mean you can connect one end and walk to the other, which is handy for long cable runs. The kit is also ready to go out of the box with four AAA batteries and a storage box. At $87.09, it is the more expensive of the two; if your jobs are limited to verifying already-exposed CAT6 patch cables, the extra capability may not be worth the price difference.
Final choice by use case
Choose the Klein Tools VDV526-200 LAN Scout Jr. 2 if you need a dedicated, lower-priced data cable tester for RJ45 runs and you don't need to trace cables. Choose the Network Cable Tester RJ45 RJ11 Wire Tracer Toner if your work mix includes finding cables in walls, under carpets, or in bundles, or if you work with both telephone and network cable. For a pure data install, the Klein Tools tester gives you the core verification tool; for a service tech who has to chase down unknown runs, the toner is the more complete kit.
