Just wanted to pass along my recommendation for owning one. I got one about a month ago and practiced a little at home with a wire above ground so I see what the receiver was "seeing." Finally got to use it on a job today and it put me right on the compromise in the wire. I only had to dig one hole as opposed to estimating in the past. For those that have never used one it literally pinpoints where the fault is. Saved me a good hour on the job. For me the time saving is secondary to the mental frustration that comes with locating. I showed up at a second call today and was excited to locate the fault and had the same result. If you don't have one and do enough repair/locating work this is a must. It is an investment up front but it is an investment. My new favorite toy. Thought I needed to pass this along for anyone out there like I am.
