I did not care for this mistake!
This thing was not worth what I spent. I noticed the wire purchase signs and ignored then thinking it was just a sellers pitch. Now I understand why. I called in and spoke to Tom about the wire that is advertised and realized why they recommend it. I ordered the wire and compared it to the petsafe wire in this kit and with what I had buried and I was very impressed with the quality of the wire. I was thankful of the discount that was given and I can not complain about that wire. But this wire break locator was a piece of junk and would not recommend it to anyone trying to help them fix their fence. I read the reviews before I purchased and it looks pretty mixed up, but I have to put in my two sense because i would not want someone making the same mistake as I did. I have to admit though that the Customer service with this company was very helpful and gave me all ideas before I made my decision. Good idea to call and speak with someone about it and get all the details your looking for.

It was Ok, but hard to find
This wire break locator was a wise purchase to make I thought, but I could understand how some people get frustrated easily with it. I dug up quite a few spots, but eventually found it. Not exactly what I was expecting, but it did work for the most part.

Not worth the money I spent. I was warned but did not listen. Here I am again, looking for other ways to figure this out.

The dog fencing company who came out, told me I'd need to replace the entire wire around my 2 acre yard as the "wire was old and disintegrating" when they pulled on it. My dog had been diagnosed with cancer, and I wasnt willing to invest $900 for a repair. When I decided to try a repair on my own, I found the wire to be just fine.
It took me a while to get up the courage to attempt a repair. My knowledge of all things electrical is low. I watched a video and read the directions many times. When I grasped the concept, it was easier than I thought it would be. I found two breaks in the wire and am thrilled with your product and the results. You've saved me hundreds of dollars.
Two additional notes- My dog is better than ever. He's full of life and up to his old tricks. The fencing company in my area is now out of business.
Your support line is wonderful and very knowledgeable.

Can Save on Service Calls
For less then the cost of a single repair you can try to locate and fix any wiring breaks, which always seem to happen when no one can make it out on your schedule. It was not the easiest piece of equipment to use, but it works and saved me from an expensive service call.

Great product easy fix
Our fence stopped working this past winter when there was about two feet of snow on the ground. It was impossible to look for the break until the snow melted. By then, the dogs had completely forgotten about the fence and would wander out into the street when people walked by, the neighbor's yards, etc. After unsuccessfully trying the Radio Shack trick, I spent about two hours one afternoon digging up sections of our fence looking for a break with no luck. Another search on the Internet for a solution brought me to Amazon and this product. The reviews were mixed but I was at my wits end so I decided to give it a try. Just prior to receiving the kit, Karen from e-mailed to tell me the package would be delivered by the end of the day. She also gave me several useful tips to help locate the break. I will include them here because they work with or without the product:

1. Check the area near where you have already spliced the wire (driveways or sidewalk crossings)
2. Check areas where you have had breaks in the past. Depending on what was used to splice the wire, the splices may have broken or partially broken.
3. I recommend using the type of splices that come in your locator kit(direct ground burial rated). Plain electrical tape and splices that aren't made to be underground will fail at some point. These areas are vulnerable to having repetitive problems.
4. Once you locate your break (s), it may be better to replace a section of wire vs having many splices. (replacing a 50ft section of wire is easier than doing 5 splices along that 50 foot run)

The box arrived as promised, I read the instructions and the next day I spent about ten minutes setting up the detector and transmitter. I tuned the radio toward the bottom of the AM dial, and aimed it at the twisted wires coming out of the transmitter. While I was receiving a station, I could clearly hear the two sets of tones produced by the transmitter. I walked to a section of fence I had uncovered previously to start my search. I placed the radio over the exposed wire and could hear the solid tone emanating from the radio. I followed the wire until it disappeared underground. I was able to track the wire using the tone as a guide. After about ten minutes I got to a section of the fence where the tone stopped and no matter which direction I went, the tone did not pick up. I dug and voila! The break was uncovered. I repaired it with the splices included in the kit. It turned out to be a failed previous splice! I had not unburied this one in my attempts to find the break because it was only four months old and I could not imagine it would have gone bad so soon. I highly recommend checking old breaks prior to purchasing this product but if that doesn't locate the breaks, this product will. Happy hunting!

Not very happy
I bought this thinking it would work. I sent it back to petsafe because I was very unhappy with the results that I got. I was able to find the break, but not only did it take me forever to find the break, my system never worked again with the wire until I had it replaced. A lot of wasted time and money.

Crappy and NOT worth my time!
I installed my own dog fence a few years ago. Recently I did some work that caused my fence line to get broken. My first thought was that I needed to replace the whole wire, I wish I could have just went with my first instinct. Although it was not to hard to use, it took up most of my day to try and find a break because there was a few times that sounded off and I dug up the wire for no reason. The last time I dug up the wire, I ended up snapping it, creating yet another problem area for myself. Lesson learned! I bought new wire and just re installed the wire again. Now worth my time and effort to attempt to find the darn thing.

Not what I expected, but did find the one break. Was hoping for better, but just bought the wire after trying it.
Just got this wire break finder yesterday. I found a wire break in my dog fence system quickly as described but did not help me with the second one. It was a little difficult to use, took me about 2 hours to find locate and repair the one break in the wire. I ended up buying a whole new wire and ended up finding three sections that were on the verge of breaking and the other break that was a lot bigger than I would have had to even fix it to begin with. I ended up purchasing the thicker 14 gauge wire that was recommended, it seems super durable and I really believe it will last much longer than my dog. I can't complain at all about the quality of that, but seriously should have just thought about replacing the wire to begin with due to how crappy the old wire was.

Wished it worked better
Don't get me wrong, it works, but not the way I expected or the outcome I wanted. There is more to it and the directions weren't fully clear. The transmitter radio looks like junk and it got me frustrated. I am currently looking to purchase wire now because I do not feel like doing this whole process over again because I never could find the break.
