Watch out

  • VDV526-200 includes the tester and one remote; VDV999-200 is the remote only.
  • Klein calls the standard tester-and-remote package a kit; a crimper or tone probe is not included.
  • Tone generation is built in, but tracing needs a separate probe.
  • Candidate listings with tone kits, crimpers or punchdown tools add items to the standard package.

Why people pick it

  • Wiremap shows exactly which pins are crossed, open or shorted
  • Detects split pairs, which a simple continuity tester misses
  • Self-storing remote and a long battery life
  • Tone generator for tracing a cable with an optional probe

Know before you buy

  • RJ45 only: no coax or phone jacks
  • No length, PoE or link-speed readings
  • A verification tool: it can't certify Cat 6 or 6A performance
