ALLOSUN EM2280 Pro Ultrasonic Leakage Detector Kit, Blue

defective cheap plastic! not sure if it's going to work((... updated: as expected it worked for 10mins and stopped!! cheap cheap cheap plastic

I recommend this to anyone.. I drive trucks and I found a lot of air leak that I didn't hear. I would not find with just my ears.

The product is easy to use and really straightforward. I like that it comes with a ultrasonic emitter to calibrate the instrument..Once you’ve done that you’re ready to go do your inspections. The only thing I wish it had is a decibel read out for noise level

I have not been able to find air leaks in the chassis of my motorhome. This is what I bought it for and there is a possibility that I do not have any leaks at this time. The rear suspension drops over a 24 hour period, so I am still looking for leaks. The generator part works great. Put the generator in my car and found lots of leaks around the doors that don't seal all that well. Still evaluating!

I have found several early stage bearing defects using this tool already.
