An amazing device for locating and characterizing all kinds of sounds for such tasks as diagnosing faults, finding leaks, etc. Very sensitive and very accurate! I have seen similar devices from other manufacturers but the cheapest one costs more than ￡8K and the prices range upwards from there to well over ￡20K. Given the quality, advanced technology, and capabilities of the Fotric TD2e, it's an incredible value!

I usually don't leave reviews, but I have to on this product. Been looking for a good sound leak detector for HVAC industry and this tool work amazing. Finding the tiniest leak when it is a pressurized system or even when pulling a vacuum on a anything. Worth the $$$$ especially with the visual camera to pinpoint the leaks. Only thing I wish was the product came with a case so I can keep it from getting damage.

I bought this to track down hard to pinpoint noises and squeaks. For example, the other night we heard a cricket chirping someplace in the house. It was so hard to tell where the sound was coming from!

The next night when it started chirping again I thought I'd see if I could find the cricket with the TD2e. I found the frequency range of crickets online and used that to narrow the range on the TD2e. Within a few seconds we discovered why we couldn't find the cricket. The sound was clearly shown coming up through the floor from under the house!

Pretty amazing tool.

It’s a lightweight camera and easy to use. The photo quality is good. Overall, it fulfills the purpose of the camera. Obviously, it’s not the same as a €15,000 camera.

Been chasing an air leak in our plant for weeks. Old ultrasonic tool kept giving false positives — drove me nuts. Plugged this in, swept the room, and there it was — clear as day on the screen, from like 50 feet away. The frequency display on the right side made it obvious which sound was the leak vs background noise. Took maybe 10 minutes total. Honestly, I was skeptical at first because the price seemed too good for this kind of tech. But nope. It just works. Already ordered a second one for our other facility.

Pulled it out of the box and honestly thought they sent the wrong thing — looks and feels like a way more expensive piece of gear. The housing is sturdy, not that cheap plastic feel you get with some budget tools. Screen is crisp, controls are intuitive enough that I didn't even glance at the manual. Fired it up, pointed it around my shop, and started finding air leaks in under a minute. Lightweight too — walked around for a good hour without my arm getting tired. For what this costs vs what it does, the build quality alone is a win.
