Almost everyone here had the D-tek select but most are having trouble finding 410 leaks. Do fine on 22. Couple bought the Bacharach Informant 2 and are not happy. Lately a couple have gone with the TIF ZX and have been happier. Seems like 410 is a hard gas to find the leaks on.
That I would get a little more chatter on this subject but be that as it may, I told my troubles to the good folks at Inficon and they sent me a replacement cell and new battery free of charge. I will let you know if the results are better, the battery is a upgrade, not the same as what came with my leak detector.
