I have been using a d-tech leak detector for years and it is great. Looking to buy another one but they have changed the technology of it (it is now called a d-tech select) and I heard today that they were recalled by the factory. I am nervous about buying a new d-tech. The d-tech sensitivity is rated at .1 ounce a year which is very good. I just saw an ad for a Yellow Jacket AccuProbe which has an amazing sensitivity of .003 ounce a year. Has anyone tried either one of these new leak detectors to see how well they work?
