a few thoughts of mine.

i have a whisper ultrasonic tester as well. it has found many leaks. but...it is an skill to use i have found. and it is not the magic find every leak tool. it is part of the tool kit. i use over the ear headphones with mine.

i have made a number of test jigs. with several gauges, ball valves and various attachment hoses. all to be able to break air systems into smaller chunks and test which side leaks and the one that doesnt.

i use kids bubbles from the dollar store. like a dollar for a quart. and a sponge and spray bottle. (thanks richard)

i also have about a zillion dollars worth of various air fittings in a couple of carry on cases on hand.

like richard and steve and others, i have helped many find leaks. quite a few of you have been to my place and we have searched for and found leaks. and in some cases didnt
