Review: Will detect a lighter a foot away! - Works great, way better than the soapy water trick. Does take a little bit to warm up and tricky to learn and use for the first couple times. I love it, tots worth the $10 I spent on it.
Review: Not very sensitive - This review is for both the General Tools and Instruments PNG1, and the Mastech MS6310. I was looking for a detector to find a leak in the propane system on my RV. Conclusion: In my testing, the Mastech was easier to use, quicker to respond, and much more sensitive. In my opinion, The Mastech MS6310 is worth the extra $13 when it comes to the safety issues and cost associated with gas leaks. Read on for details.... GT&I PNG1: This device came in a nice retail blister pack with 2 AA batteries and had readable directions. It seems to be made of decent quality plastic for standard handyman and home use, but is definitely not a tradesman's quality product. In testing, It was easy to use, but slow to respond, so the leak detection was a slow process. On the first day of testing there was no breeze outside, and it detected only one of 3 leaks. on the second day with a 4MPH breeze, it couldn't detect even the larger leak. I returned this product for refund. Mastech MS6310: This device came in a nice retail box, but obviously is targeting the Chinese market and was covered with Chinese characters. The box contained the unit, a carrying case, and instructions, but did not include batteries. The instructions were readable, but had the common spelling/word errors of a Chinese product. The quality of the unit itself was fine for handyman and home use. Performance wise, this gas detector was far superior to the PNG1. The Mastech almost instantaneously alarmed near leaks, and found 2 addition very small leaks that the PNG1 couldn't detect even when I knew where they were. It also detected all 3 leaks even in a 4MPH breeze. The unit has a sensitivity knob that you adjust until the tone stops, so if there is residual gas in the area you can reduce the sensitivity to find the leak location. I kept this product for future use. Note: Both units require a couple minute warm up time for maximum sensitivity.
