Query: SIMPLE and EASY cable tester

This is an excellent little cable tester for field techs who install LAN and coax cabling. It's simple - no fancy bells and whistles that aren't needed. Unit is small, rugged, and easy to spot in my toolbox. Metal belt clips on each unit are handy. Green/red/orange LED lights quickly show if the Ethernet 1/2, 3/6, 4/5, and 7/8 cable pairs are open, shorted, failed, crossed-over, or split. Will also confirm if your LAN cable is properly shielded. LED lights on both ends is nice feature. Auto-OFF feature saves battery. Basic coax testing for checking if connectors are properly seated. Not cheap, but a good tool for the money.
