Review on 🔍 Klein Tools VDV501-852 Tester for Accurate Locating Abilities by Todd Look

The toner function didn't seem to work with the supplied Klein Tools VDV500-123 toner sensor and I followed the instructions. With a cable from my ethernet switch connected to the top RJ45 port, pressing the tone button on the Scout 3 will trigger the tone function on wire #1 and the probe will immediately begin to sound anywhere near the Scout 3, no matter where she is. shows. Placing the probe tip next to the correct wire on the switch only results in a 60Hz hum. On the Scout 3, each wire is traversed the same way, then the wire pairs are traversed, starting with 1-2, 3-4, 5-6, 7-8 all pairs, the sensor signal is turned off, and the sensor tip pressed against it Cable produces the same 60Hz hum, that's it, no sound. If I can't make it work on the bench, it won't work on the field. This is one of the reasons I spent a lot of money on this tool as there are cheaper toners out there but I needed a quality tool that worked. Either I'm doing something completely wrong, or the Scout 3 and/or the toner sensor is defective and I don't want to return a working unit. Other RJ-45 test functions seem to work fine. In response to another reviewer's complaint that the battery didn't fit, you have to rotate the battery 180 degrees so the battery cable doesn't interfere with the correct placement of the battery in the battery compartment.
