    Best leak finder I’ve used. Still not perfect but it’s pretty good. Found a lot of evaporators with it.

    I have used for about sixty days. When this unit works, leak detection is accurate. Unit will intermittently shut off. May or may not power back on. Will power on later and function for a few minutes and shut off or will function through the remainder of the job or even the day. Cannot operate a business with a tool that is not dependable.
