Good info too! *by A***A on November 20, 2020* **Warning: Short Review, Long Use Directions***How to use unit effectively*Overall, I am extremely happy with this unit. I feel this unit is fairly priced with the build quality in mind and the "bare-bones" of the unit itself. Bare bones being a good thing with this because its such a great value, and anything else would increase its price a lot and for what you bought this for (to find leaks) it will do that job super effectively. Looks like you can mount this to a pole or a tripod stand if either reach is an issue, or you know the leak is in a location but the leak is intermittent.I only got this unit in today, but immediately put this to use and put some tape over the speaker so I can have this unit close to me in close quarters work. Most likely not water proof, but if that is a concern and it's raining, put a tarp or umbrella up. Any other reason, there's more problems than just that gas leak your trying to find.Overview:Comes with a page to pretty much tell you this needs to warm up with the sensor powered on (the "click" from the sensitivity dial on side), what the unit does, and what you can expect from this unit. I thought the black part on the sides were at least somewhat rubberized, there not. This needs (qty. 3: AA battery) to be powered on, physical sensor housed at the red part of the goose neck. Count to around 20 seconds with the unit switched on with switch in front, and sensor powered on to "warm up sensor".How to set unit up:After warming sensor, just barely get the LED light on the "sense indicator" in front of unit to not light up any part of the indicator levels (in likeness to the unit being off). The speaker in front, in tandem with the LED indicators, will increase in level and intensity the more of a concentration is noticed in the air. You can test your unit set up with any gas source, like a butane source like a cigarette/barbeque lighter, a natural gas source like a stove top, or any propane source (I posted a picture of manual along with this review).How to use unit effectively:After setting the unit up and now able to use it for gas leak testing, you will soon find out when you put this unit into the area containing the leak, the unit will go crazy. This is the learning curve of the whole thing, and it's a small one: just adjust the sensitivity down to how you had it when you turned the unit on. This will effectively "desensitise" the unit so it wont go off when the sensor is in the presence of the traces of gas lingering in the air because of the leak. This works to your benefit because you already know the area of the leak, now you want to pinpoint the leak site. A lesser sensitivity will now only pick up when the sensor is in the stream of the leak.To practice this:Take your outdoor propane grill or a lighter turned down to just barely letting gas out, but don't ignite a flame. The unit will sound off to this. Decrease the sensitivity of the unit to where it's either not sounding off anymore or just barely going off (depending on your needs and/or situation). Now by letting more gas out, the unit will sound off more insensely. THATS HOW YOU PINPOINT A LEAK.That is the part where EVERYONE HAS FAILED TO DEMONSTRATE, from hours of googling and looking at videos on youtube, to reviews on here. There is a person who did a video in full spanish that either demonstrated this, or eluded to the fact that you can, on youtube. ### ⭐⭐⭐⭐⭐ every RVr should have one. *by M***Y on December 17, 2024* A great tool for checking lines and connections for propane leaks. It's a safety tool and all RV owners should have one ### ⭐⭐⭐⭐ Terrific sensor *by R***L on January 8, 2025* Third one I’ve purchased, one for me and two for friends. Works great at detecting the smallest hint of propane. It has helped stop dangerous situations with propane leaks on my rv and allowed me to pinpoint the leak. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/81692598-combustible-gas-detector-gas-detector-alarm-portable-natural-gas-tester](https://www.desertcart.vu/products/81692598-combustible-gas-detector-gas-detector-alarm-portable-natural-gas-tester) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
