Excellent leak detector

I was trying to chase down a very slow AC leak in my car was certain it was the compressor shaft seal or evaporator. Within 5 minutes I found the leak coming from my condenser which was replaced previously but was a defective part. Very happy with this tool !

Good detector

This unit does the job when needed. You have to ensure that the end is clean when using. The key is you have to trust the detector. It will find the leaks and batteries last a long time.
