I do transport refrigeration and had a hard time finding leaks I’ve used sniffers and bubbles this thing you can hear small leaks undetectable by a sniffer even boost leaks air brake leaks also has frequency transmitter you can check seals with like freezers or back of a refrigerator truck or fridge well worth the money although the light gage is not that sensitive but you’ll definitely hear leaks also has a stethoscope great value most useful tool I’ve bought for my trade ... show more

  • These are great. HVAC Pro.
I bought these for all of our service techs after the first one help us find a leak in 5 minutes.

  • Works - - kind of
Helps me diagnose steam traps. Kind of works, picks up a lot of electronic noise (old florescent lights). touching the contact probe "grounds" it and reduces the noise. Flexing the probe reduces the noise.. I make it work for now.

  • Noisy like a cheap 1970s transistor radio.
Poor quality at best. Too much static on headphones to hear what you are listening for.
