Lance, we recently bought the hellium sniffer. I'm having mixed results as it seems to detect ANYTHING other than the ambient atmosphere. Is there a demenstration DVD or web site I can see to better utillize this tool. I've read through the manual included but some of the specs are way over my head... I'm a leak detector not an engineer lol. Thanks Lance

If its the Gow-Mac then keep it on low sensitivity.

Thanks Sde, will try

I use my helium sniffer on almost every job.. Matheson product, easy to use and you know when you hit it.. it screams.

Leakyg, have the Matheson, I agree the best around. Problem is the boss dosnt want to pay to fix... Thanks tho
