8 Port Coax Cable Mapper, Tester, Tracer, and Toner - Commercial Grade Coaxial Wire Continuity Checker

Very happy with purchase, use almost every day at work. This is the best set yet and Ive use three other brands. I can honestly say I highly recommend this to anyone working with cable

Simple tester that works.

Easy and accurate

Nice mapper

A good unit for identifying cables except that, per the instructions, you have to verify the absence of voltage on each cable before hooking this unit up. It does not have voltage detection and seemingly no voltage protection. If you accidentally connect to a sat receiver or power supply fed line there goes this unit.
