Fantastic item. Just shut off fluorescent lights first, they put off a ton of noise. Found a leak in less than 60 seconds. People who have issues with this don’t know how to use it properly or patiently. It’s really not complicated. I had a leak I couldn’t find with UV dye or soap. This saved my behind and made a happy customer with the first use.

Por mucho, mejor que los detectores que tiene que “oler” el refrigerante. Es súper rápido hacer verificaciones con este equipo y es muy sensible. Excelente herramienta de diagnóstico para los trabajamos en HVAC.

UPDATE: 12/24/19. Almost a year, and still working well. I use this fairly often with a fleet of buses to find pesky air leaks. If there is a big leak, no problem - that is audible. But those small ones... that's what this is for. Narrowing down where the that tiny leak is. Works great. Finding air leaks in air brake systems is a pain. This makes it a lot easier. And it is great for doing a quick walk-around check. Just have someone release the parking brake and apply the foot brake while walking around and pointing this tool all around the vehicle. If there are no leaks, it won't register a thing. Pretty slick. If there is a leak, you can quickly narrow down to at least the area, if not the exact spot. I didn't care for the included wired headphones. They work, but the cord is a pain, especially if you need to use a creeper under the vehicle. I kept running over the cord or getting restricted in movement by the cord. So I improvised a better solution. Ordered a bluetooth transmitter and a bluetooth headphone. No dangling cord! Yay! There are a lot of options to choose from. I chose these three items: Transmitter: https://smile.amazon.com/gp/product/B01EHSX28M/ref=ppx_yo_dt_b_asin_title_o06__o00_s01?ie=UTF8&psc=1 Headphones: https://smile.amazon.com/gp/product/B00F54Y6GU/ref=ppx_yo_dt_b_asin_title_o06__o00_s00?ie=UTF8&psc=1 Short cable: https://smile.amazon.com/gp/product/B072TYZ89H/ref=ppx_yo_dt_b_asin_title_o06__o00_s01?ie=UTF8&psc=1 Used a little patch of velcro tape to attach the transmitter on top of the unit, just above the display. The cord is just the right length to wrap around the unit from the plug to the transmitter. And the headphones fold enough to still fit in the case. (a little tight, but it all fits!) The transmitter and phones are rechargeable, so an occasional recharge will be needed. But they last for hours. They paired pretty easily, and it's not hard to turn on each one before use, and shut down afterwards. Just have to get used to a little button pressing. INFICON, if you're reading this, maybe consider making a model with bluetooth built-in? That would be great.

No sensaba correctamente y al ponerme los audífonos solo se escuchaba un ruido de interferencia que lastimaba mucho los oídos .

I got this for a few different reasons but one use is for an inflatable dinghy that is losing air over a weeks time. I wanted to find where the leak is but really can't find it anywhere. Now I have used a similar unit (might have even been this one) while plugging a mold up during resin transfer molding (RTM) and it really helped out. I can't return this at this point but I'm just hoping I can come across something to where this can really help.
