Has anyone had any consistent or mostly consistent luck with finding 410a leaks with a hand held leak detector other than the trusty big blue. 3 times in the past 2 weeks my infijunk has failed me and putting me in the crosshairs of my boss. went on a call and a system was 3 lbs low couldn't get a single beep out the thing. boss goes out the next week(this week) finds leaking evap in 5 minutes he added 4lbs so it was a good leak just not enough to hear I guess. 2 days ago had the same thing happen except it was liquid line solenoid leaking. He is using the yellow jacket accuprobe and I used it in the past when it was a shop tool and had no luck at all with 22 or 410. Ive heard good things about the h-10s I just don't really favor the bulkiness. I have a previous co-worker who had very good luck with a tif zx-1 however they only make the zx model now( the same?). I plan to keep my infijunk for r22 because it has never let me down with r22 however 410a is just inconsistent. Anyone having any luck with any available model replies are much appreciated!
