Review: Found a leak soap or UV dye wouldn’t. It’s made for HVAC, not tires! - 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.
Review: It works for me! - 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.desertcart.com/gp/product/B01EHSX28M/ref=ppx_yo_dt_b_asin_title_o06__o00_s01?ie=UTF8&psc=1 Headphones: https://smile.desertcart.com/gp/product/B00F54Y6GU/ref=ppx_yo_dt_b_asin_title_o06__o00_s00?ie=UTF8&psc=1 Short cable: https://smile.desertcart.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.

## Questions & Answers

**Q: how small of a leak will it measure?**
A: Very small

**Q: would I need the transmitter device to leak check air conditioning coils etc?**
A: This is a simple tool to hear the whistling of high pressure air going through a small opening.  The high frequency pitch is picked up by the microphone.  You won't need anything else to operate this.  I prefer to use my own headphones instead of the ones in the kit, but that is a personal preference.  It also has a sound bar so  you can see it, too.  You don't need to listen, although I find it helpful.

**Q: if I pressurize my underground pool skimmer line with air, would this be practical for locating a leak?**
A: I don't believe it will help in this application.  To detect the leak, you must be able to see the line and place the unit relatively close to the hose.  So for your application, you would need to expose your lines.  If your pool skimmer lines are visible, it is easier to inject a dye, such as a UV dye, and shine a UV lamp to find it.  If your lines are not visible then you would need to dig up the line to look for the leak.  When I had an underground leak, I hired a person to find it for me.  It was worth the money for the one time repair.

**Q: Is good for bearing friction detection?**
A: Hello and thank you for your question. Yes, with the optional metal contact probe (711-703-G1) Whisper can detect malfunctions in certain mechanical components, bearings included! The contact probe is included with the version that comes with the accessory kit (711-203-G1). Simply screw the metal contact probe to the tip of Whisper and touch it to the suspected mechanical component. For the best experience, use a pair of headphones to utilize Whisper's heterodyne feature. Properly functioning machinery sounds smooth and clear, whereas malfunctioning machinery may produce grinding, scratching, or other irregular noises.

### ⭐⭐⭐ Jury is still out
*by A***. on August 19, 2021*

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.
