Fault Locator


	Finally a true RF-null fault locator that is cost effective for the do it yourself owner of invsible fence type containment systems.

We have spent the last 5 years attempting to locate a capable and simple wire fault locator that works on the same principle that our professional level locators do. Unsatisfied with the Rf-choke and AM radio process and also severely dissapointed in the fault locator made by Petsafe that also uses an AM radio we went on the search. Wanting to find something that truly worked like our professional ones but we wanted it to cost around the same as a service call. Now we have that available!!! A simple and truly effective way to track wire and locate faults in maintaining your system. Comes with directions and a secure caring case for storage all you need to add is two 9 volt batteries. We have produced a video showing the use of this very locator to find wire breaks, bad splices, and simply tracking or locating the wire. It locates within a few inches allowing most repairs to be done with little digging. Cutting average fault locating and repair time down to less than 15 minutes. This unit has been field tested by our own staff and given Dr. Hogan’s very own seal of approval.

The Underground Wire Locator is designed to locate the path of non-energized wires behind walls and underground. It is also capable of locating a specific circuit breaker, pinpointing wires before drilling and verifying dig sites underground. The effective range is up to 3 feet deep and up to 1000 feet in length of course distance is affected by interference in the area and the quality of ground available. The alligator clip leads make it simple to connect the transmitter to electrical wire, CATV coax, telephone drops, irrigation control wires or metallic pipes.

This product is made in Asia and although it functions in the same manner as the commercial units it is a consumer level product and therefor not as durrable as commercial units. The actual testing and evaluation of the product was done by me personally. I discovered that although this is a relatively inexpensive product its actual performance in locating breaks in my particular application often exceed the performance of my commercial units. I include a very cheap set of ear buds with this locator which are not guaranteed to work.. If you have long runs to locate on you may want to invest in pair of light duty earphones from your local Walmart..

DFNA provides a 90 day replacement/repair warranty on any defective equipment. After the initial 90 days the locator has a lifetime flat fee repair agreement for the original purchaser. Please contact us if you need more information.

“I have a half-acre lot with the Invisible Fence wire around the perimeter. The break was about 400' from the transmitter in the longest direction.

I put new batteries in the locator transmitter and receiver and grounded the transmitter through the ground wire in an electrical outlet. The tone from the receiver was loud near the transmitter and diminished as I moved out along the wire. The null was easy to detect. As I approached the point where the break was located, the receiver tone died out completely. I then attached the transmitter to the other end of the fence wire and approached the break from the opposite direction. Again, the tone died out completely. The gap where there was no tone was about 4', so I was able to isolate the break within a couple of feet. Before buying the locator, I tried the RF shunt/AM radio method, which got me nowhere.

My experience differs somewhat from the instruction video on your website. In the video, the receiver emits a tone but no null at the break, whereas in my case, the tone disappeared. I tried using headphones, but the background static was to loud when I turned up the receiver volume to try to hear the fading tone, I was concerned about damaging my hearing.

The break turned out to be a failed splice. The splice was near a FIOS box that Verizon buried in my front lawn a few years ago. The Verizon contractor must have severed the invisible fence wire and spliced it back together. However, the connections were sloppy-- just twisted wire ends covered with electrical tape. I was never told about the splice.”

Dr. Hogan,

Thanks for all the insight and assistance in finding and fixing the break in my invisible fence. The locator worked great and I was glad you allowed me to purchase one of your test units. I had attempted to use the Petsafe wire break locator and it ended up being a waste of $70. I also had a local dealer come out and try to find the break and he was unsuccesful but still tried to charge me for the visit. Can you believe that? When I got this locator I connected it to the unit as you had instructed. I followed the twisted pair in my system out and around my yard until I went full circle. No break found. After calling you I connected it to the other lead and followed in the opposite direction. After going only about 15 feet out the twisted pair, which goes about 60 feet to the perimeter, the signal faded to almost nothing. I dug in this spot and found one of the wires was broken within 6 inches of where I dug. It appeared that the wire had been nicked either in installation or maybe by a lawn plugger and it eventually corroded the copper inside the insulation causing the fault. this explained the system working and not working intemittently. I don’t know why the dealer didn’t find the break but atleast I didn’t pay the $140 he wanted for coming out and trying. My dog is now thrilled to be loose again after being kenneled for 2 months while I dealt with this issue. I thank you and my dog thanks you. Les, Sherman Oaks, CA

I wanted to write and tell you about my success with the locator. It took me only about 10 minutes to find the problem. It was a bad splice. Now I know what you meant about the 3-M pinch splices not being good splices. It appeared to be fine but was actually full of corosion. I fixed it but left it above ground until I get one of your splice kits. I know I have at least 3 more of these 3-M splices in my system so I will need to get enough splices to replace all of them eventually and also some extras. On a side note I also used the locator to help my brother in law this weekend. He just bought a house and we used it to trace and fix a broken coax cable, locate his sprinkle valves and track his low voltage landscape lighting wire. It probably saved him $200 to $300. Chuck T.

Just used your locator for the first time. I’m a contractor who does a lot of remodeling. We used the locator to trace and locate electrical wires in the walls before we began demolition. I can say it has easily already paid for itself on the first job allowing us to salvage the existing wiring and simply relocate as needed. Thanks! Fernando V., Houston, TX

Thanks for the tips on finding my break. Its nice to get the customer service along with a great price. If you remember I was the man with the system that the dealer wanted $125.00 to come and locate the break and after he got here said he was unable to locate the problem because of my poor installation and cheap system.. I bought the locator and was unable at first to find the break. After calling and talking with you I followed your advise to tap into the boundary wire beyond the twisted pair. After doing this I walked right to the break and lost tone in about 10 minutes. Dug up the wire there to find an original splice done with a so-called water proof wire nut. Fixed it with the kit I got from you and I’m up and running again. Thanks you! Dean W. from the Buckeye State.

The locator worked great. I had used or attempted to use the Rf-choke method and the Petsafe break locator RFA-50 and neither ever got me within 20 feet of a break and often walked right past the break. It had taken me a couple hours and digging up and re-burying at least 50’ of wire every time. Today I got your locator added the required batteries connected it to one of the wires and grounded it as directed in your video. I tracked the wire and came to a spot where the tone stopped. I dug there and pulled on the wire and found the break less than a foot from my hole. Fantastic product! Now all I have to do is return the Petsafe product. Also liked your prices on the repair kits.

Dear Dr. Hogan, I recently had a break in my dog fence and had no idea where it was. I called the initial fence installer and they were more than happy to come out at $65 for the service call and an additional $35 every 15 minutes. I am located in MA and it has been a very cold winter and digging is very difficult due to the frozen ground so I did not have this company come to fix the fence. I was searching online how to find a break and came across the dfna locator and figured I would give it a try estimating a service call would be $200+. I found the break within 15 min and had it repaired. The locator put me within inches of the problem area. This has been the best investment that I have made. Not only did the locator work great, but the customer service was by far the best I have ever had and the payment method was easy and the shipping was prompt. I am also a landscaper and will use this To locate customers fence breaks or irrigation valves. Thank You for saving me money, time, and my sanity. Dave, MA

I just bought the unit last week. I live in Minnesota and have 2 Norwegian Elk hounds that run around on 5 acres. About a month ago the invisible fence I have quit working. (Loop light went out.) I checked my loop with an ohm meter and sure enough, it had a break. I tried to locate the break with the Petsafe wire break locator and it was of no help. I hooked on your Underground Wire locator and within 10 minutes I had the spot. (There was a crack in the frost across the driveway and that's where the tone went away!) I thawed the ground for 6 hours with a fire, dug down 3 inches and there was the break. I spliced in a new piece of wire and my dogs are able to once again run around. Sissy, Bear and I thank you much! Paul Cedar, MN
