Many techs can find leaks with beepers. Some dye can be mixed in
with the lubricating oil. And then detected with eye sight, or
ultraviolet light. If the system is under pressure, some folks
use soapy bubbles.

I would tend to avoid technicians who use tarot cards, dead
chickens, or salt shakers.

In my case, I've not tried dyes. However, I've had considerable
luck with leak beeper, and soap bubbles.
