Told my boss we needed one of those things for years, he always said it was a gimmick. Spent a whole afternoon last week chasing a ghost pressure drop with my regular tools. Finally borrowed a buddy's thermal camera and found the leak in two minutes. My pride still hasn't recovered from being shown up by a gadget from the tool aisle.

Oh man, I totally get that. That book is a serious downer. My own take on it almost made me give up on reading for a week.

And now that stuff's just permanently on his resume.
