Hi, was wondering who of you use an ultrasonic leak finder.
Can you share your advice on its usefulness?
Brand/model?

Thanks!

Did you try digital absolute vacuum gauge? I find it really useful and over time it actually teaches you what kind of leak equates to different looses in vacuum. 

Now i get sub 10mbar every time (sub 20mbar inside few min on bigger parts).

Small bag punctures are really rare (once you start covering infusion spiral and ends of infusion mesh with some tape).

I think its a must have item.
