It isn't an expensive locator, but it does the trick and makes life easier for less. I don't like the length of the probe, because it isn't capable of making a turn down a 90. But, popping off a fitting isn't all that tough. I suggest noise canceling headphones to listen for the indication. Paid for itself the first time, due to the amount of clock digging around would have eaten up. Big props on the price for the ease of use and functionality, well worth the cost.
