    • ILD-200 works great on R410A. Wish I bought this sooner.
Color: Ild-200 With Infrared Sensor
This review is for ILD-200. It is a shame they mix all the reviews together for 3 different models. I had a leak on a R410A mini split that I couldn't find with leak spray. This thing arrived in one day fully charged. I've never used a leak detector before. I read about two sentences of the instructions and turned it on. I checked several different parts of the system. Even on high sensitivity I got zero false positives. When I got to the area of the leak the beeper went off 100%, even when I turned down the sensitivity. It is actually a pretty big leak although the bubble liquid barely indicated it even after the detector showed where it was. I may never need this again but I'm keeping it. This thing is a solid performer on R410A which I believe is one of the harder ones to detect. ... show more

Color: Heated Diode Sensor Ild-100h
Worked surprisingly well, used it to test a 1234yf extremely hard to find slow leak on a 2025 vehicle. I did manage to find the leak prior to purchasing this with a old CPS leak seeker that does 134A. Was skeptical using that one since many go off on anything, it's hard to trust them. But purchased this to update to the newest freon. And it worked, detected the leak soon as I placed it near the area. I'm, pleased, esp for the price, it's not a bad purchase. ... show more

    • Immediately Found Undetected Leak
Color: Heated Diode Sensor Ild-100h
After failing to find a refrigerant leak in a Goodman Heat Pump Unit condenser coil, this device found it it 5 minutes - not in the most likely place I suspected due to oil trail. I don't know that I would have ever found the slow leak...what I call "bunny tails" bubbles behind a frame piece. With such a wide range of prices on these devices I was not sure that this would work due to economical price. I do have an Elitech scale thats great. I did trust the reviews on this detector. I hope it lasts for the next leak I encounter. ... show more

Color: Heated Diode Sensor Ild-100h
I bought this after I seen the top 10 detectors or 2025. It was number 3. I own a snap on detector which is actually a inficon which was number 1 on list but this one is far better bang for the buck. The charger is a c type also which I like better than buying batteries for.

    • Great tool at a great value
Color: Infrared Sensor Ild-300
I purchased the idl300 and it arrived yesterday. Today, during a service call I was able to confidently confirm a leak in a r410 evaporator coil. The detector has already paid for itself. It’s a steal compared to some of the detectors on the market. I really hope it holds up.

Color: Ild-200 With Infrared Sensor
Haven't found a leak with it yet. I use the dye normally, the secret to my magic. When it's failed, this hasn't helped so far. I'll update my review if anything changes. Update on review. Probe gives false alarm every time it's gently pumped while trying to reach in to tight places. USELESS. 30 Day send back warranty. I'm a day too late so I'll eat $200 ... show more
