I have used this product, using all the attachments and in every concievable manner possible and it has worked without fail. If I had a failure it was because the hookup and not the operation of the tool. I have also used some of the other Amprobe tracers and Test Equipment and all have performed great.

"The AT-1000 worked well for me until problems developed. First, I would suggest avoiding any of Amprobe's testers that feature the supposedly convenient drop-in battery compartment ""feature"". It has a poor contact design that became intermittent in the receiver over time. Since it was out of warranty at that point, I disassembled it to discover one of very fine wires connecting the battery contacts was broken off, and the other broke while I was fixing the first one!

Then it developed a second problem where the receiver sensitivity became intermittent. At this point I decided to send it in for service, but discovered the fee to repair and recalibrate the unit was going to cost MORE than a new set sells for. Until I get around to taking a stab at fixing it myself, it sits on the shelf gathering dust. Too bad; I like Amprobe products, but this situation is both economically and environmentally disappointing. It also makes me hesitant to purchase a new tracer from them if they can't fix their products."
