General Precision Gas Detector "Gas Dog"

The device is good. Bit is not thought off button. But if you carefully use and get used to, it is not a problem.

Gas Dog worked fine. This was my first such tool and it did take a little time to get familiar with its operating mode. Patience is the key to using this unit. It may take 10 seconds before it registers the leak. Again, the importance of patience in scanning joints for potential leaks cannot be ignored.It found two small gas leaks in the crawl space under the house. All is now well.

I bought this for my Mom. She kept smelling gas outside her house, near the meter. She could pin point the leak with this tool.It works for natural gas quite well. The Gas Dog really sniffs out the gas and lets you know exactly where the leak is. First we tested if on the gas stove. We turned on the gas to a burner but did not light it. We just had it on for a second. Then we tested with the Gas Dog and it alarmed and lighted up signifying high gas content air. It works as intended. We checked to see if a leak I tried fixing under the stove was indeed fixed. No leak shown. That was a relief. I'm not a gas plumber so I was not certain my repair took. The Gas Dog showed no leak.The price was right on this item. It has saved us countless $$$ in gas plumber costs. It just works.

Was renovating a house and there was always a faint background smell. Finally decided to check propane lines with gas line liquid solution. Nothing. Did it again and nothing. Bought NGD7201 on spec since smell remained. It found leak within 30 seconds of scanning pipes on a fitting that had not shown any bubbles on soap test. Easy to use. Sensitive. Did the job.

I picked this up after smelling gas after replacing a stove in my home and not being able to find the leak with bubble solution. This unit not only found the leak in no time (at the shut off valve), but I checked the rest of my gas lines in the house and found other leaks.My only issue with the unit was it didn't come up as "ready" when I turned it on. It does a start up test, etc.But the instructions clearly tell you to check the connection at the probe's end, and I found I had to tighten it just a little to get it working.Well worth the $115 I spent on it. Especially seeing how the $40 units fail in reviews to find small leaks.
