We've spent some time getting the trace feature to work. The device that emits sounds for detection barely made a sound. The audio was inconsistent and very low. The actual test device was a bit cheap. Lightweight plastic and less than intuitive user interface. Someone may like the device, but we had to send it back. We used to use Fluke equipment, it was an attempt to get something less expensive for new technology, remember you get what you pay for.
