I smelled gas in my house, but could not tell where it was coming from. Tried the old soap in a squirt bottle and still could not find the leak. I went on line to see if I could find something that would help and came across the General Company's "Gas Seeker". After reading mostly good reviews on the product, I thought I would give it a try.Simple and easy to use. Just push the button, let it warm up and simply pass it over your gas pipes and it will beep and show two different lights if it detects any gas. One light for a small slow leak and another for a larger leak. I found the first leak right away, so I kept checking more gas connections and found four more leaks!. It was money well spent and the price reasonable.
Pros: Easy to Use, All In One, Accurate, Light Weight
This detector is easy to use and detects large leaks. For example, if you turn on a kitchen gas burner and don't light it, you can hold the detector over the gas flow and it will detect the gas. Of course you can also easily smell the gas since the gas company adds an odor. I was trying to find a small leak due to a loose pipe fitting. I could get a whiff of the smell of the gas but couldn't be sure which joint was leaking. Unfortunately, my nose is more sensitive than this detector so it didn't help me. Ultimately, a more expensive detector was able to detect this small leak. So this product is useful only if you are seeking leaks of a certain magnitude. Since natural gas in my community has the odor added to it, I didn't find this detector helpful and I returned it.
I had a leak at my sons townhome in the gas line feeding the furnace. Even the highly paid house inspector with a high end gas "sniffer" said that the smell was due to the furnace belching upon startup and the furnace room should have better venting. I didn't believe him and purchased this unit and, behold, found the leak. After two hours of draining water heater and moving some plumbing to get to the leak, problem solved! The house inspector, if he had done his job, should have recommended this be fixed PROIR to us purchacing this townhome.
If you fall into the category of amateur home-repair person, or just want something that is better than soapy-water, this is the device to have. This no-frills gas detector will provide you an ease of mind, as it does exactly what it is supposed to do. After having the detector delivered, I immediately went to my shop and tested the sensitivity of the product. It has two different levels that are displayed through a yellow and red LED light, along with two- different sounds that correspond to the light color.
If you are looking for something that will provide the exact amount of explosive gas in the air – this is not the product. Save your $50 dollars and put it toward one of the $200 - $300 testers. However, if you want something to have in your toolbox that will give you peace of mind – this is for you. And besides – it is made in the good ol’ USA!
We just converted from propane to natural gas and were smelling a 'gas' odor so we ordered this pen style gas detector. It works great, we detected a small leak and were able to fix it without calling for help. It is good to have around for any future problems. We are very pleased with the quality.
We had a small leak in a natural gas fireplace. We had a repairman investigate and he was unable to find it. I tried to detect a leak with the detergent/bubble test method and was unable to find it. With this little natural gas detector, I found the problem in a matter of minutes. It is easy to use but sensitive enough to find a very small leak. Great product! It paid for itself it's first use!
I had a very small natural gas leak in my basement above the suspended ceiling. I could smell the gas, but the use of a liquid detector fluid was of no help. The chemical the gas company puts into natural gas can be detected very easily by your nose, way before any explosion can take place, so the leak must have been very small. I started looking for some type of electronic gas detector and was expecting to pay a hundred dollars or more. I then came across the General Tools Gas Detector.
I ordered it and used the detector to check each pipe joint, and soon discovered a very, very small leak coming from one side of a joint. Repaired the joint and now no leak. The only negative is that since this is a passive unit (no sucking of air into the unit), it is a little slow in detection, but for the cost it was well worth it since non-passive units cost hundreds of dollars. Will use on all my gas line repairs so there will be no surprises.
I smelled gas in our furnace room but could not locate the leak. I ordered this and it arrived quickly. I was able to find and fix the leak immediately. May not be what the "professional" needs, but for the homeowner it is perfect.
I rerouted a gas line to fit a new stove and was pretty sure I could smell a gas leak, so I purchased this gas leak detector. It alarmed on the connection that was leaking instantly. After I resealed the pipe, this gas leak detector verified the connection was no longer leaking. Easy to use and well worth $40.
The product performed as advertised. I tested it on a leak I already knew about and it confirmed the source. The only drawback is the fact it does not have a pump like the testers costing hundreds of dollars do. Because of this, you have to get very close to the leak for the sensor to pick it up. But for the price, I think it is better than traditional soapy water.
Pros: Easy to Use, Compact, Nice Design, Easy Installation
Installed the batteries & it warmed up & immediately went to fault mode (beeps at 1.5 sec intervals & yellow light on) I changed batteries, locations & indoor/ outdoors but still got the fault code. I returned it, will order another one. Hope this one will work. I like the concept.
Pros: Easy to Use, Good Size & Weight, Light Weight
Very simple to use to detect gas leaks. Audible and visual alarms. Noise is not obnoxious and changes with concentration as well

Review 14 for Pen Style Natural Gas Detector
Turned on but did not work at all
PostedAugust 10, 2013
No, I do not recommend this product.
I read the reviews and knew that some people had issues with this unit, but also saw that is actually worked for others. Well, I thought I would try my luck. I followed the directions completely and made sure it was zeroized in a clear-air area. I tested the unit at various locations including directly in the gas line. The unit didn't do a thing. No chirp, no light, nothing. I tried many times. I ended up taking it back....I got a dud. If you like to gamble, go ahead and try your luck with this one. I'm not headed to Vegas any time soon.
Keeping in mind the price point of this device, it has done well. For my purposes (i.e. home and a few rentals) this was a perfect non-professional solution. I tested it on a known leak both an obvious leak and then a smaller tough leak. It detected both. This gave me more confidence with unknowns. Use is easy and seems to be a solid built detector. The mesh screen in the tip seems a bit exposed but otherwise exactly what I needed.
We had a gas leak coming from the line to our fire pit and could not figure out where it was coming from. My husband replaced the valves and we were still smelling gas. We purchased this tool and it helped us discover the leak was actually at the base of the fire pit just under the concrete in an elbow joint that got corroded. It has lights on it that turn yellow for small leak detection and then turns red for a larger leak and it beeps accordingly, faster for red.
Pros: Easy to Use, Accurate, Good Size & Weight, Light Weight
I bought this product prior to installing a tankless water heater which required changing out some gas line. It worked very well, sounding an alarm when even a little residual gas was in the line. Although I did the traditional soapy water test on all the new gas unions I found I felt more confidence in this detector to reassure me there were no gas leaks. The Home Depot price was the best I found (dramatically so compared to some sources) and shipping was quick enough that I had it before I started my project. A+!
