Hey guys, I am looking at a Kent-Moore J-41416 ultrasonic leak detector. This particular one was built specifically for locating leaks in evap systems on GM vehicles. Accutrak built it for Kent-Moore and you can only buy it through SPX Kent Moore new for around $1200.00

I have found a few on ebay used for a fraction of that cost and was just wondering if anyone has used one for finding leaks in HVAC systems. Looks just like the VPE to me so I don't know why they wouldn't operate the same way.
