Summer is pretty much winding down. I kept using the same two leak detectors that I've been using since last year. The ZX for R22 and the Fieldpiece infarad for 410. I was reasonably happy with their performance. There was a couple of small leaks that I didn't find but for the most part they got the job done. How about you guys? What worked for you? Is there really a leak detector that is excellent at finding all leaks with all refrigerants yet? Over the last few years I've tried almost all of them. I haven't tried the H10 Pro yet. Any feedback on that one?
