Review: Klein Tools ET450 - The dust motes dancing in the afternoon sun always seemed to mock me, a visible representation of the frustration I'd been battling for months. I’m not one for writing glowing reviews—I usually keep my opinions to myself—but the sheer quality and engineering I’ve found in Klein tools have become impossible to ignore. They simply make things that are built to last, tools you can trust when the chips are down. ​And the chips were definitely down. ​The well on my property had been acting up for months, a source of endless headaches and low water pressure for my family of four. I’d brought in a parade of so-called "experts," well companies who offered plenty of expensive advice but no real solutions. Every single one was unwilling to put in the hours, to roll up their sleeves and truly troubleshoot the core problem. The consensus was grim: drill a new well. ​But I had a second, forgotten wellhead on the property. "Dry," they had all declared, or at the very least, "not enough to support a family." I couldn't shake the feeling they were wrong, but to prove it, I faced a daunting task: connecting the waterline and the electrical conduit—a challenging 71-foot run between that lonely wellhead and the main well house. I couldn't just tear up the driveway or risk severing other hidden power lines to the house. I needed to know exactly what lay beneath the soil. ​For a week, I was glued to my computer, diving deep into obscure well forums. It was there, amidst the threads of seasoned DIYers, that one name popped up: the Klein Tools ET450 Advanced Underground Circuit Breaker Finder and Wire Tracer Kit. The reviews were mixed, of course. Some users swore it was a toy, others claimed it only worked for short distances. But I was desperate and frankly, pragmatic. I'd been quoted $1,900 just for a specialist to identify the underground lines. I thought, for a mere $230, why not try this tool and educate myself? ​I pulled the trigger and waited. ​The day it arrived, I was ready to treat the frontyard like a construction zone. What I can say now, with absolute certainty, is that this tool is the REAL deal. It took patience, yes. I had to learn its language, finetune the sensitivity settings, and train myself to listen to its signals. But once I did, it performed a miracle. ​The ET450 didn't just help me locate one thing; it mapped out the entire subsurface puzzle. It identified the exact, safe path for the new waterline and, crucially, the existing electrical wiring, all buried three to four feet underground. Not only did it save me from a costly excavation disaster, it located wires twice—and these wires were hiding under concrete! ​The knowledge I gained and the confidence I built by doing the work myself were invaluable. But the true, stunning payoff? This little kit saved me from the grim fate the experts had predicted. I didn't have to drill a new well, nor pay for additional, unnecessary troubleshooting support. ​My total estimated savings: an astonishing $82,000. That's not just a review—that's a testament to good old-fashioned quality meeting modern engineering, proving that sometimes, the only expert you need is a determined person with the right tool.
Review: Excellent Wire Tracer! Worth Every Penny! - This thing works amazing and has saved me a ton of time! I was tracing an underground wire, and when the signal started dropping off, I dug down and found the wire was broken right there. The range is impressive too! I had it connected to a light pole on one side of our college campus, and it was transmitting all the way to the other side. Highly recommend!

## Questions & Answers

**Q: Can this find a dead short?**
A: Depends on the situation.  It’s more for finding the cable pathway, but could help find a dead short.

**Q: Can this unit trace wires that are in flex?**
A: Yes

**Q: Can I trace from a light fixture back to a switch? (I can not find how to turn on a few lights in my new house)**
A: this tracer work's better on energized circuits but will also work with de-energized circuits. if your light is not energized, then hook up the transmitter to it and then use the receiver to follow the wire through walls and ceilings to find your switch. You may have to set the detection level higher on the receiver for this use.

**Q: Will this tracer generate an audible tone when connected to 14/2 speaker wire?**
A: Don’t know. I’m deaf and just look at the visual readout.
