I used this leak detector to find auto AC leaks and it worked great. I found several leaks. Here you can set the sensitivity. There are no replacement tips, so if it gets dirty, just wipe it down with rubbing alcohol. It will emit a pulsing beep and if a leak is found, it will rattle. It works great and comes in a hard case for good protection. It is rechargeable and comes with a charging cable. It has a plastic body with a rubber sleeve to protect it from bumps if dropped. This is a great leak detector that I definitely recommend. Compared to other brands' prices this is a great deal and the shipping was very fast.
