So far is working nicely
It finds the leaks, just make sure you install the sensor before checking for leaks

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.

Reliable
HVAC service tech since 2011. This is the best sniffer I've used. So far I'm 3 for 3 locating leaks. Only thing I don't like is there's no mute button and sometimes the warm up seems to take a really long time. Would definitely recommend.

Very Sensitive Leak Detector
I selected Inficon's TEK-Mate 705-202-G1 as my first refrigerant leak detector in preparation to enter the HVAC/R field. It's the only "real" leak detector I own (the other being an extremely inexpensive no-name halogen type). I haven't used it more than a handful of times, so take this review accordingly. I've used it in residential, commercial (walk-in cooler) and automotive applications so far. It's very sensitive -- maybe even too sensitive for its own good. Even on the low setting, I had a hard time pinpointing what was a very small leak in the evaporator coil of the walk-in box. I like the fact that it's made in the USA and came with name brand alkaline batteries, so you can get started right away. The built in alarm is very loud. You might like that if you're working in extremely (and I mean extremely) noisy machine rooms. I thought it was too loud for every other situation, and the constant wailing of the alarm during the sensor's start up period really got on my nerves. If I didn't think I'd invalidate the warranty by doing so, I'd pop it open and put something over the beeper to quiet it down a little.

No product support
After 2 years and used only 3 times it will not pass warm up cycle. Changed sensor, still never stops alarming after start up. Called Inficon and was told that I have to go through whoever I purchased from to be able to send in for repair. Not good support at all.

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 !
